Accomplishing this goal, as Meng’s thesis argues, requires detailed, full-system simulation tools that can simultaneously evaluate power, performance, and temperature. Her award-winning thesis includes the design of such simulation methods and leveraging these methods for the development of dynamic optimization policies for computing systems.

This prestigious award is just one of a number of awards that the ambitious engineer has received throughout her Ph.D. career. In 2012, Dr. Meng won the Best Paper Award at the High Performance Extreme Computing Conference; in 2011 she won the A. Richard Newton Graduate Scholarship Award with her advisor, Assistant Professor Ayse Coskun (ECE), at the Design Automation Conference; and in 2010 she received the Google Scholarship at the Google GRAD CS Forum. Furthermore, Dr. Meng has won a number of awards from Boston University, including the Outstanding Graduate Teaching Fellow in the School of Engineering and the 2009 ECE Graduate Teaching Fellow of the Year Award.

Dr. Meng started her academic career at the University of Science and Technology of China (USTC), where she earned a Bachelor of Engineering Degree in Electrical Engineering in 2004. She went on to earn a Master of Applied Science in Electrical and Computer Engineering at McMaster University before coming to Boston University in 2008 to pursue her Ph.D.

Dr. Meng simultaneously pursued career advancement while maintaining her academic workload. She landed an internship at the Intel Corporation, and another at Sandia National Laboratories.

Currently, Dr. Meng works as a software engineer at CGG, a French-based geophysical services company. “To be specific, I am working on developing software modules for modeling and imaging geological structures in the exploration [of] seismic field,” Meng clarified in an email correspondence.

When Dr. Meng reflects back on her time at BU, she remembers, “I was very lucky and grateful to have Professor Ayse Coskun as my advisor. [She was] a role model for me.” Professor Coskun felt similarly, noting, “Jie is a very hard-working researcher and she has the necessary perseverance to succeed. Seeing Jie graduate successfully as my first Ph.D. student and continue to her career has been among the most satisfying accomplishments of my time at BU.”

In 1963, the College of Industrial Technology (CIT) offered only three degree programs — in technology, aeronautics and management — and occupied a single, four-story building, but the former aviation school’s new dean, Arthur T. Thompson, was bullish about CIT’s future. He aspired to do no less than transform this dot on the Boston University map into an accredited engineering program, and to develop engineers with “the capacity for responsible and effective action as members of our society.”

Thompson began to work this transformation on February 27, 1964 — 50 years ago today — when CIT was officially renamed as the Boston University College of Engineering. Since then the College has grown to become one of the world’s finest training grounds for future engineers and platforms for innovation in synthetic biology, nanotechnology, photonics and other engineering fields, attracting record levels of student applications, research funding and philanthropic support.

Between 1964 and 2013, the number of degrees conferred annually has increased from zero to 281 bachelors, 184 masters and 53 PhDs; enrollment from around 100 to 1416 undergraduate, zero to 394 masters and zero to 349 PhDs; faculty from 10 to more than 120; advanced degree programs offered from zero to nine masters and six PhDs; and annual sponsored research dollars from zero to $52 million. Meanwhile, the College’s position in the annual US News & World Report’s annual survey of US engineering graduate programs has surged from unranked to the top 20 percent nationally.

At the same time, the College’s faculty, students and alumni have significantly advanced their fields and spearheaded major innovations in healthcare, energy, information and communication, transportation, security and other domains.

Building a World Class Institution

The infrastructure for the world class research and education taking place at today’s College of Engineering was built in stages.

During Thompson’s deanship from 1964 to 1974, the new Aerospace, Manufacturing and Systems Engineering departments received accreditation, with the Manufacturing Engineering program the first of its kind to be accredited in the US. The College also instituted the nation’s first BS degree program in bioengineering and expanded to five BS and three MS programs in five fields. Between 1975 and 1985, when Louis Padulo was dean, the College’s student body grew from 250 to 2481; minority and female enrollments skyrocketed; degree offerings rose to 24 BS, MS and PhD programs in eight fields; full-time faculty increased to 67; and sponsored research exceeded $3 million.

When Professor Charles DeLisi (BME) became the new dean in 1990, he recruited many leading researchers in biomedical, manufacturing, aerospace, mechanical, photonics and other engineering fields, establishing a research infrastructure that ultimately propelled the College to its ranking in US News & World Report’s top 50 engineering graduate schools (realized in 2003). A case in point is the BME Department, which DeLisi turned into the world’s foremost biomolecular engineering research hub, paving the way for his successor, Professor David K. Campbell (Physics, ECE), to oversee the department’s receipt in 2001 of a $14 million Whitaker Foundation Leadership Award and discussions leading to additional support from the Wallace H. Coulter Foundation. Between 1990 and 2005, as the number of full-time faculty rose to 120, research centers to eight, and PhD programs to seven, the College’s external research funding surpassed $26 million.

When Professor Kenneth R. Lutchen (BME) took over as dean in 2006, he aligned the curriculum with undergraduates’ growing interest in impacting society, redefining the educational mission of the College to create Societal Engineers, who “use the grounded and creative skills of an engineer to improve the quality of life.”

Lutchen rolled out several programs to advance this agenda, ranging from the Technology Innovation Scholars Program, which sends ENG students to K-12 schools to show how engineering impacts society, to the new Engineering Product Innovation Center (EPIC), a unique, hands-on facility, that will educate all ENG students on product design-to-deployment-to-sustainability. He also ushered in a new era of multidisciplinary education and research collaboration by establishing the Systems Engineering and Materials Science & Engineering divisions along with several new minors and concentrations. Meanwhile, professional education opportunities surged on campus with the introduction of eight new Master of Engineering programs and four new certificate programs.

Moving On to the Next 50 Years

That said, what do the next 50 years hold for the College of Engineering? For starters, upcoming educational initiatives include increased integration of digital technologies in courses; new programs with the schools of Management, Education and Public Health; continued efforts to build the engineering pipeline through outreach to K-12 students; and the Summer Institute for Innovation and Technology Leadership, which recruits companies to host teams of ENG and SMG students to tackle targeted problems.

BU also plans to construct the Center for Integrated Life Sciences and Engineering Building — a seven-story, 150,000-square-foot facility that will include interdisciplinary research space for faculty and students in systems and synthetic biology (expanding the College’s recently launched Center of Synthetic Biology (CoSBi)) — within the next 10 years, as well as a 165,000-square-foot science and engineering research building. By 2016, ENG expects to add about 61,500 square feet of new lab and classroom space.

In its first half-century, the College of Engineering — through its students, faculty and alumni — has made its mark on several fields while improving the quality of life around the globe. If its rich history of high-impact education and innovation is any guide, the College can expect many more life-enhancing achievements in the coming 50 years.

Engineering in the Alps

February 25th, 2014 in Alumni, Courses, Faculty, Graduate Programs, Graduate Students, News-CE, News-EP, News-ISS, Research, Research-EP, Research-ISS, Senior Design, Students, Undergraduate Programs, Undergraduate Students

Kevin Mader (ECE '08, MS '08, who is teaching at ETH Zürich, bikes in one of the side valleys of Engadin in the Swiss Alps.

Kevin Mader (ECE ’08, MS ’08), who is teaching at ETH Zürich, bikes in one of the side valleys of Engadin in the Swiss Alps.

As a master’s candidate studying Photonics at Boston University, Kevin Mader (ECE ’08, MS ’08) decided to become an Undergraduate Teaching Fellow, a position that allowed him to work with students and help them master difficult concepts.

“I felt like I could help students because I had just struggled with learning the concepts a year before and could relate well to what they were going through,” he said.

The experience made Mader realize he wanted to become a teacher and today, he is a lecturer at ETH Zürich in Switzerland, where he is hoping to inspire the next generation to get excited about engineering.

“I think that a lot of students lose interest in science and engineering early on because it becomes too technical before it gets interesting,” he said. “I hope to try and make it exciting without watering it down too much.”

Prior to living in Switzerland, Mader’s roots were in the United States, where he lived in California, Ohio, Oregon, and Massachusetts. Still, moving abroad wasn’t quite the challenge you might expect.

“For some things it is no adjustment at all – there are Starbucks and McDonald’s restaurants on nearly every street corner – but for other aspects getting used to a new language and a different culture can take some time,” he explained. “Luckily, students seem to be pretty similar all around the world and Zürich is a very international city so it’s never a problem finding interesting people and somewhere to fit in.”

As an undergraduate studying Electrical Engineering at BU, Mader worked closely with Senior Lecturer, Babak Kia, on his senior design project. Like in Switzerland, Mader never had any problems finding other researchers he could collaborate with effortlessly.

“He was a very effective team player, espousing a humble leadership style and patiently sharing his thoughts and ideas with his team,” said Kia, who served as Mader’s customer during senior design.

Mader’s team, Esplanade Runner, was tasked with enabling a robot to navigate a Google Maps route while avoiding obstacles in its path. Known as autonomous navigation, the project was assigned a few years before Google Street View cars were popularized.

Calling the research one of his “most valuable experiences at BU,” Mader said, “Our project was particularly cool since it was tangible: make a little car follow a route and avoid obstacles. It was also deceptively simple, and I learned how difficult it is to make timelines and get everything running on time. We spent a few nights in the lab banging our heads against the wall trying to synchronize our vehicle, compass, sensors, and GPS.”

The hard work ultimately paid off and their team won the ECE Day Best Presentation Award that year.

“Kevin could hardly contain his drive and enthusiasm throughout the project,” said Kia. “He has such a natural ability and curious mind for exploring the unknown that is just a joy to witness.”

After earning his bachelor’s degree, Mader decided to continue his studies by pursuing a master’s in Photonics at BU.

“Initially I was intrigued by Photonics because I had no idea what it really was and had studied in the building by that name for years,” said Mader. “After taking the introductory class I was surprised by how complicated imaging really is – iPhones make it so easy – and how much potential there was in the field.”

Mader had completed a summer internship at the Center for Biophotonics at the University of California, Davis, where he looked at how cellular spectroscopy and imaging could be used to detect cancer. Upon returning to BU, he decided to build upon what he learned by taking a course on imaging and microscopy with Professor Jerome Mertz (BME).

“What struck me about Professor Mertz from my first interaction with him was how much interest and passion he had for the science he was working on,” explained Mader. “He seemed like one of those people who would continue to do the exact same thing even after winning the lottery because he enjoyed it so much.”

Mader went on to work on his master’s thesis in Mertz’s laboratory, where he worked on improving bioluminescence imaging so that a small group of cells, like a tumor, could be detected without using lasers or X-rays.

“Kevin was great to work with – really creative,” said Mertz. “He could always look at things from different and unexpected perspectives that were really intriguing. I think he’ll make a great professor someday.”

Since completing his master’s, Mader has taken more steps toward eventually becoming a professor, including earning a Ph.D. in Electrical Engineering and Biomechanics from ETH Zürich.

He has also earned a Pioneer Fellowship from the university, which will allow him to work toward pairing microscopes, MRIs and CT-scanners with tools that will turn pictures into meaningful statistics.

“There seems to be sufficient industrial interest. The real challenge will be connecting with the right people at the right times,” he said.

As Mader balances research with teaching, he continues to give his all in both.

“I think one of the best ways to really understand a topic is to have to disseminate it to other people,” he said. “In particular, I enjoy trying to connect abstract concepts like parallel computing to everyday ones like card games with friends.”

Truly committed to being the best teacher he can be, Mader can often be found tweaking his lecture slides minutes before a talk, even though he’d finished preparing weeks before.

Said Kia: “I have no doubt, not even for a second, that he will become a highly effective professor and that his deep passion for research and discovery will be surpassed only by his immense passion for his students.”

Atlas Changing the Workout Experience

February 18th, 2014 in Alumni, Graduate Students, News-CE, News-EP, News-ISS, Recognition, Research, Research-CE, Senior Design, Students, Undergraduate Students

Mike Kasparian (ECE ’12, MS ’13)

As many of us try to stick to our New Year’s resolution of going to the gym more, we often find ourselves looking toward apps and equipment that can help us keep track of our progress.

Jawbone and Nike Fuel Band are just some of the wearable products on the market that allow you to keep track of this data, but what if these devices could be more customizable?

2013-8-9_Michael

Mike Kasparian (ECE ’12, MS ’13)

That’s the idea behind Atlas, the company founded by Mike Kasparian (ECE ’12, MS ’13) and his preschool friend, Peter Li.

Atlas tracks and identifies exercises, counts reps, calculates burned calories, and evaluates form. It also displays workouts live and is compatible with many popular fitness apps such as MapMyFitness.

Said Kasparian: “It’s one thing to come up with a great idea that will disrupt a technology, but it’s another thing to formulate the idea into a business and develop it into something that will one day not only generate revenue but also be in the hands of consumers.”

Li initially came up with the idea and contacted Kasparian to help with the hardware. Techstars, a startup accelerator in Austin, provided them office space, funding, and mentorship.

It was not an easy decision for Kasparian, who had a stable position at Philips Healthcare, to leave his day job. However, he took the risk and now holds the position of Chief Technology Officer (CTO) of the growing company.

The company gained funding through a campaign on indiegogo, a web platform that helps people raise money for new ideas and products. Atlas has surpassed its $125,000 fundraising goal, collecting over $450K.

Even though there is a lot of uncertainty associated with this venture, Kasparian feels that providing people with a personalized workout experience outweighs the risk.

Kasparian, who studied Electrical Engineering at Boston University, attributes the Department of Electrical & Computer Engineering’s senior design course as having a significant impact on his career. He said, “It was really the first time I was able to fully apply all of the technical skills from my coursework toward a legitimate project.”

As his advisor, Professor Bakak Kia gave Kasparian invaluable help and guidance during senior design. Kia is very proud of Mike, saying, “To reach this level, where he is competing with some of the most innovative companies in this field, speaks volumes about Mike’s vision, ability, and the value of the education he has received at BU.”

While working on the project, MINSensory, for senior design, Kasparian said he learned the importance of both collaboration and taking feedback. He did both well, too, winning the top team prize, the P. T. Hsu Memorial Award for Outstanding Senior Design Project, and an individual honor, the Michael F. Ruane Award for Excellence in Senior Capstone Design.

Later, his M.S. research project involved designing the hardware platform that would be used in the Atlas wristband. Professor Ajay Joshi (ECE) was Kasparian’s academic and research advisor, and he advised him during the platform design process. Joshi believes “the fitness band market is just picking up” and said he hopes “the Atlas wristband becomes the preferred choice of most fitness enthusiasts.”

Kasparian continues to remain close to the department, serving as one of the judges for senior design last year and graduating with his M.S. in December.

Looking Beyond the Lab

Postdoctoral associate, George Daaboul; research associate, David Freedman; and lecturer and entrepreneur, Rana Gupta (SMG) were among the Boston University participants of the NSF I-Corps program.

Postdoctoral associate, George Daaboul; research associate, David Freedman; and lecturer and entrepreneur, Rana Gupta (SMG) were among those participating from Boston University in the NSF I-Corps program.

Many engineers have great ideas for products, but unfortunately, they don’t often have a background in business that will allow them to bring their designs to market.

To help with this problem, two Boston University research teams recently participated in the National Science Foundation (NSF) Innovation Corps (I-Corps), a program that encourages scientists and engineers to broaden their focus beyond lab work through entrepreneurship training.

“We had been trying to bring some of our ideas to a commercial state when we heard about the program,” said David Freedman, a BU research associate in the Department of Electrical & Computer Engineering. “It seemed like a great fit for us.”

Freedman and postdoctoral associate, George Daaboul, had been working closely with Professor Selim Ünlü’s (ECE, BME, MSE) research group trying to determine how their technology, IRIS, used to detect viruses and pathogens, might be applied in doctors’ offices, hospitals, and emergency care centers. They soon decided that forming an I-Corps team would allow them to evaluate the commercial potential.

Teams receive $50K in grant money and consist of an Entrepreneurial Lead (Daaboul), a Principal Investigator (Freedman), and a business mentor. The researchers asked BU lecturer and entrepreneur, Rana Gupta (SMG), to take on the latter role.

Also participating from BU were Assistant Professor Douglas Densmore (ECE) and Research Assistant Professor Swapnil Bhatia (ECE). They pitched Lattice Automation, technology that will allow technology by the Cross-disciplinary Integration of Design Automation Research (CIDAR) group to transition into commercial products. Ultimately, they hope to create software that will help synthetic biologists work more efficiently.

“Our technology is building upon state-of-the-art techniques in computer science, electrical engineering, and bioengineering,” explained Densmore.

Over eight weeks in the fall, participants attended workshops in Atlanta, Ga., met with researchers from the 21 teams, followed an online curriculum, and spoke with up to 100 different potential consumers of their technology – a process known as “customer discovery.”

Through this experience, Freedman and Daaboul quickly learned that introducing a new technology to customers might not be the right approach for their research.

“We decided instead to focus on the pains customers had with existing technologies and hone in on how we could alleviate those,” said Freedman.

Added Daaboul: “Finding out what people really needed before developing a technology really allowed for a much different perspective than what I’m used to.”

Much of the knowledge gained through I-Corps will be used to advance science and engineering research. Some products tested during the workshops even show immediate market potential by the conclusion of the curriculum.

“I would recommend this program to anyone working in science or industry,” said Freedman. “Not only did this change how we think about our research, we also learned how to better tell our narrative.”

Associate Professor Kotiuga talks with a student discussing his research project at the Department of Electrical and Computer Engineering's annual fair.

Associate Professor Robert Kotiuga (ECE) discusses his research project at the Department of Electrical and Computer Engineering’s annual fair.

It’s been a bitter winter in Boston, but that didn’t keep students and faculty from making their way toward the Photonics Building Colloquium Room on January 22. Anxious undergraduate students looking for research opportunities mingled among the 28 tables of Boston University researchers at the recent ECE Undergraduate Research and Lab Job Fair hoping to find opportunities to gain hands-on engineering experience.

The story of the research fair goes back four years ago when Dean Kenneth R. Lutchen spoke to matriculating freshman about the importance of research. While listening to the talk, Professor Mark Horenstein (ECE) realized that while entering students were being encouraged to engage in research, no one was telling them how.

In response, Horenstein started the annual ECE Undergraduate Research and Lab Job Fair as a way for undergraduates and faculty to explore mutual interests related to research and for students to ask about available research positions. The event also provides a public forum in which faculty can showcase what is happening in their laboratories. “This is a get-to-know-you meet-and-greet event,” says Horenstein.

View photos of the event on Facebook.

Watching presentations and submitting resumes to BU faculty and graduate students, about 75 students attended this year. Two sophomores, Dean De Carli (EE ’16) and Matthew Owney (EE ’16), were scouting for summer and fall positions.

“Even though I didn’t get any research jobs, I was able to connect with the faculty,” said second-time attendee, De Carli. Owney added that he is looking for any opportunity since it’s his first time attending the fair.

Horenstein tells younger attendees, such as Alexandra Miller-Browne (CE ’17), that it’s important to “build up your skills as time goes on; don’t get discouraged.”

People on the other side of the table have a similar thought process. Dr. Traci Haddock, Executive Director of the Center for Synthetic Biology at BU, says, “Most students have no experience, but we will take anyone who is interested.” For example, she is looking for students to help develop the iGEM team’s website and build genetic devices this summer.

Third-time veteran, Associate Professor Robert Kotiuga, changes his presentation every year but remains steadfast in his belief that though people will always possess different areas of expertise, “it is important to be passionate about the project.”

Every year since the program’s initiation, the event has turned out eager attendees, and 2014 was no exception. Students continue to return each year, hoping to gain experience and take advantage of the department’s available opportunities.

The Search for Satisfying Solutions

February 6th, 2014 in Events, Faculty, Graduate Programs, Graduate Students, Lectures, News-CE, Research, Research-CE, Students, Undergraduate Programs, Undergraduate Students

Professor Sharad Malik, Chair of the Department of Electrical Engineering at Princeton University, spoke as part of the ECE Distinguished Lecture Series on January 29.

Professor Sharad Malik, Chair of the Department of Electrical Engineering at Princeton University, spoke as part of the ECE Distinguished Lecture Series on January 29.

When a bug in Pentium processors was discovered that gave rise to incorrect solutions of scientific and mathematical calculations, the company was forced to take action. The result? Public outcry and the loss of $475 million worth of earnings.

It’s been almost two decades since the Pentium FDIV bug made headlines, but its discovery led to a new research thrust in computer science and engineering – one that Professor Sharad Malik, Chair of the Department of Electrical Engineering at Princeton University, knows quite well.

“It’s an instance of how real practical concerns have driven solutions to real, fundamental problems,” said Malik.

The incident brought the examination of Boolean Satisfiability or SAT, the challenge of determining if a logic formula will ever evaluate to true, to the forefront. In proving the correctness, this problem has a direct application to hardware and software and more specifically, avoiding costly bugs. SAT was already well known in computer science, but theoretical analysis deemed it to be too difficult to be applied in practice.

Malik is one of the nation’s experts on the topic, and his group has made several critical contributions to the field of SAT solvers that are now widely used in practice. On January 29, he visited Boston University to share his findings during the Department of Electrical & Computer Engineering Distinguished Lecture Series, which brings groundbreaking engineers to campus.

The latest ECE Distinguished Lecture was attended by BU faculty, students, researchers and staff who were hoping to learn more about Boolean Satisfiability, or SAT.

The latest ECE Distinguished Lecture was attended by BU faculty, students, researchers and staff who were hoping to learn more about Boolean Satisfiability, or SAT.

Currently, there is a strong motivation to discover useful SAT solvers thanks to all of the potential practical uses, such as in applications in artificial intelligence, circuit synthesis, and malware analysis.

“It’s already very widely used in hardware verification and we’re seeing an increasing use of the theory in software verification,” added Malik.

Though the SAT problem may be relatively unknown outside computer science and engineering, a very active community of researchers exists and can be found sharing their research and questions on the website, SAT Live!

Malik notes that the biggest change he’s noticed with SAT studies over the years is a revolution in how the topic is approached.

“There has been a significant shift from theoretical interest in SAT to how it can have a practical impact,” he said. What was once considered practically impossible due to its theoretical hardness is now within reach thanks to challenge-driven algorithmic and experimental research.

Malik’s talk was the first in the three-part Spring 2014 Distinguished Lecture Series. The next talk features Professor C. V. Hollot of University of Massachusetts, Amherst, who will speak on the topic, “Regulation of Cell Populations in Individuals Using Feedback-Based Drug-Dosing Protocols.” Hear him on March 5, 2014, at 4 p.m. in Room 211 of the Photonics Center, located at 8 Saint Mary’s St.

A Google for Surveillance Videos

January 22nd, 2014 in Awards, Faculty, Graduate Programs, Graduate Student Opportunities, Graduate Students, Grants, News-ISS, Recognition, Research, Research-ISS, Students

Professor Venkatesh Saligrama (ECE, SE) and his research team address the problem of retrieving video segments which contain user-defined events of interest, with a focus on detecting objects moving in routes.

Professor Venkatesh Saligrama (ECE, SE) and his research team address the problem of retrieving video segments, which contain user-defined events of interest, by focusing on detecting objects moving in routes.

After the Boston Marathon bombings last year, it took authorities just three days to sift through an abundance of footage and find their suspects – light speed compared to the weeks it took to find those responsible for the London bombings in 2005.

Still, can this happen faster? Professor Venkatesh Saligrama (ECE, SE) thinks so, and he’s working to making that vision a reality.

The Office of Naval Research awarded him $900K for his project, Video Search and Retrieval, which will focus on developing a visual search system. Think Google but for security videos.

“Our initial idea was to develop a system that could annotate web videos,” said Saligrama, who collaborated with Pierre-Marc Jodoin at the University of Sherbrooke on early stages of this research. “That project turned out to be extremely challenging so we started to focus on surveillance videos, where the footage is obtained in a controlled environment.”

Manually searching large archives of footage can be both time-consuming and monotonous. Saligrama and Ph.D. students, Greg Castanon (ECE) and Yuting Chen (SE), are now working closely with the U.S. Naval Research Laboratory to help change this.

Professor Venkatesh Saligrama (ECE, SE)

Chen said she is looking forward to working on this project with Saligrama, who she first encountered while conducting her own research.

“I spent almost a year and a half working on an idea that employs correlating motion clues to calibrating camera networks,” she said. “When I came to BU Systems Engineering and browsed the research papers, I found the exact idea implemented by Venkatesh’s group. I was surprised and just a little bit bitter.”

From there, she knew that she wanted to study with Saligrama.

“He is an experienced researcher and just as passionate and curious as a young freshman,” she said. “I find that one sentence from him can help me through a problem that’s been troubling me for weeks.”

Chen, Castanon and Saligrama hope that together, they can make the process of searching through security footage more automated and responsive to user query video searches.

“Currently, for many YouTube videos, there are textual meta-tags that are used in the search process,” Saligrama explained. “For surveillance videos, we do not often have this so our searches need to be based purely on visual features and patterns.”

One of the challenges in video search is that activity patterns can be highly inconsistent and can occur for unpredictable amounts of time.

“Unlike image search though, videos have some temporal patterns we can exploit,” said Saligrama.

In the future, Saligrama hopes that the research will not only improve security but improve medical database searches as well.

The Engineering Product Innovation Center (EPIC) hadn’t yet opened for its inaugural semester, and it already had a wait list of students eager to register for classes in the sleek, glass-fronted Commonwealth Avenue building that not too long ago was the Guitar Center. That bodes well for the College of Engineering and the University officials and corporate sponsors who made the new facility possible.

ENG will host EPIC’s ribbon-cutting ceremony this Thursday, January 23. Among those present will be President Robert A. Brown, ENG Dean Kenneth Lutchen, local dignitaries, and key corporate partners, including representatives from principal industry sponsors GE AviationProcter & GamblePTC, and Schlumberger.

Lutchen, who is also an ENG professor of biomedical engineering, says that EPIC’s opening “now begins the opportunity for us to transform our engineering education at the undergraduate level to really create a much more powerfully enabled graduate who understands the process of designing products from conception to deployment.”

Those skills are particularly important, and valuable, now that manufacturing is making a comeback in the United States. US manufacturers have added at least 500,000 new workers since the end of 2009, energy costs have dropped, and labor costs in competing countries such as China and India have been inching upward.

Companies like Apple and GE are bringing high-tech facilities back home from overseas. While a positive development, “the problem is now there aren’t enough engineers trained in highly technological methods,” says Bruce Jordan, ENG assistant dean of development and alumni relations.

EPIC could help fill that void. “We’re hoping to set a standard for the training of engineers for the future manufacturing economy in this country,” says EPIC director Gerry Fine, an ENG professor of the practice.

Funded through the University, ENG alumni and friends, and regional industry, EPIC’s 20,000-square-foot space houses a computer-aided design (CAD) studio, demonstration areas, fabrication facilities, materials testing, and project management software available to engineering students in all specialties — from computer and electrical engineering to biomedical engineering and nanotechnology. The facility has a flexible design and offers students supply chain management software, 3-D printers, robotics, laser processing, and around-the-clock digital access to the studio’s online resources.

A representative from each principal industry sponsor, GE Aviation, Procter & Gamble, PTC, and Schlumberger, will sit on EPIC’s Industrial Advisory Board, whose primary function will be to offer suggestions on how the ENG undergraduate curriculum might be redesigned to better prepare students for employment in the years ahead.

“We want to create as many options for our graduating students as possible,” Fine says. “By teaching them some of the things that regional industry wants, we think we’re giving our students more options. And we’re making our students more desirable to potential employers.”

Representatives from the principal sponsors will also participate in guest lectures and provide case studies and projects, and the companies will offer internship and employment opportunities to qualified students. 

While other universities have manufacturing-oriented centers, most focus on basic research, but EPIC allows engineering students to put theory into practice by converting their ideas into products that could one day benefit society.

Fine has given tours of the facility to at least five teams from other universities since June. “We’re not aware of anyone who’s invested in this scale and made this commitment to undergraduate education,” he says.

“When I first heard from Dean Lutchen about the idea of EPIC, I was thrilled,” says Michael Campbell (ENG ’94), executive vice president of PTC’s CAD segment, who will serve on EPIC’s advisory board. “I always felt that my engineering education lacked that real-world perspective, that real-world exposure to the challenges, processes, and complexities of collaboration and the sophistication of tools. Now we have a chance to share all of that with students.”

J. David Rowatt, research director and technical advisor at Schlumberger, echoes that sentiment. “There were so many things I didn’t learn in school that I picked up on the job,” he says. “Some of these are clearly being addressed by what EPIC is trying to do,” which is exposing students to the entire engineering process — from conception and manufacturing to working on deadlines and understanding resource constraints.

Greg Morris, strategy and business development leader for additive manufacturing with GE Aviation, says this generation of students grew up in a world where computers and software were second nature, but tinkering under the hood of a car was not. EPIC will provide engineering students with the hands-on experience that gives them an advantage in the marketplace. “I can’t tell you how much that resonates with an employer,” he says.

Both BU and its partners see EPIC as a win-win. ENG faculty and students will benefit from a revamped curriculum and access to global leaders in innovation and manufacturing, while industry partners will interact with the University’s deep bench of cutting-edge researchers and get exposure to a new crop of engineers.

“If we tap into EPIC,” says Bruno De Weer, the vice president of global engineering at Procter & Gamble, “we can find ourselves connected with another hub of innovation that brings the very best.”

The EPIC ribbon-cutting ceremony will be held at 4:30 p.m. on Thursday, January 23, at 750 Commonwealth Ave., followed by a reception and tours for those invited. The event is not open to the public.
