“Computable Performance Analysis of Sparsity Recovery”
Crime investigation TV shows, such as CSI, commonly feature a digital forensics laboratory capable of recognizing faces and vehicle license plates from extremely blurry shots. Photo and video evidence is displayed on a large projection screen while a recognition system attempts to identify the perpetrator’s identity.
This technology exists in research labs today thanks to advanced signal processing. Various developments in signal processing, particularly in sparsity-based image reconstruction, have recently emerged with the potential to dramatically improve system performance.
Prof. Arye Nehorai is a leader in this research area, and recently delivered a lecture on the “Computable Performance Analysis of Sparsity Recovery,” as part of the Department of Electrical and Computer Engineering Distinguished Lecture Series. Nehorai is the Eugene and Martha Lohman Professor and Chair of the Preston M. Green Department of Electrical and Systems Engineering at Washington University in St. Louis.
As part of his lecture, Prof. Nehorai discussed a movement within the signal processing community to update the classical framework based on the Nyquist-Shannon sampling theorem using a new approach known as compressive sensing. Compressive sensing makes it possible to acquire and represent signals using fewer samples than classical sampling methods, under the key assumption that the signal itself is sparse with respect to some basis. For instance, although a facial image is comprised of many, many pixels, it can still be accurately represented using just a few key features. Indeed, identification of a criminal based on a low-resolution, blurry image, while unthinkable a decade ago, is becoming increasingly viable in part due to modern image processing techniques based on compressed sensing. Other important applications include hyperspectral imaging and anomaly detection.
Prof. Nehorai’s recent work has focused on a challenging and important compressive sensing problem. In particular, while it is known that dramatic savings are possible via compressive sensing, it is often difficult to say exactly how many samples are required for a specific sampling scheme (or sensing matrix). Prof. Nehorai and his collaborators have developed a suite of efficient algorithms, based on convex programming that can rapidly ascertain the number of samples needed under a particular scheme. These algorithms can in turn be used to guide the development of better sensing schemes.
Nehorai’s talk was the first in the three-part Fall 2014 Distinguished Lecture Series. The next talk features Philippe Fauchet, Professor of Electrical Engineering, College of Engineering of Vanderbilt University. He will speak on the topic, “Nanoscale Silicon as an Optical Material.” His lecture will be held October 28, 2014 at 4 pm in PHO 210.

Joint Research Focused on Medical Imaging and Image-Guided Interventions
By Mark Dwortzan
Boston University College of Engineering Assistant Professor Darren Roblyer (BME) and Brigham & Women’s Hospital radiologist Srinivisan Mukundan are exploring a strategy that combines a new optical imaging device developed by Roblyer with emerging magnetic resonance imaging (MRI) techniques to probe malignant brain tumors during chemotherapy treatment. Their research could enable clinicians to monitor the effectiveness of chemotherapy over the course of treatment and implement changes to chemotherapy drugs and dose levels as needed.
The project is one of five now receiving funding through an ongoing partnership between Boston University and Brigham & Women’s Hospital. On September 12 at the BU Photonics Center, Dean Kenneth R. Lutchen and Dr. Steven Seltzer, Chair of the BWH Department of Radiology, announced the second year of the partnership, which has already provided one year of seed funding to projects ranging from image-guided cancer drug delivery to early detection of heart disease.
“The goal is to leverage synergies between Brigham & Women’s Hospital’s Radiology Department in imaging and image-guided interventions with the College of Engineering’s strengths in developing new materials and technologies as well as novel techniques for processing images and large data sets,” said Associate Professor Tyrone Porter (ME, BME, MSE), who is coordinating the partnership. “The hope is to stimulate research collaborations between the two campuses and develop a National Institutes of Health training program in clinical imaging and image-guided interventions.”
The brainchild of Lutchen and Seltzer, the BU-BWH partnership brings together world-class expertise and equipment from Boston University entities such as the BU Photonics Center and the BU Center for Nanoscience & Nanobiotechnology, and from the BWH Department of Radiology, home to the National Institutes of Health’s National Center for Image-Guided Therapy and the Advanced Multimodality Image Guided Operating Suite (AMIGO). Joint research between the two campuses could result in less invasive, more accurate medical imaging and image-guided interventions.
“There’s no question that in so many dimensions, imaging is at the foundation of a tremendous amount of potential breakthroughs in medical discoveries and practice, but there are huge challenges from a scientific and technical point of view,” said Lutchen. “We’ve got tons of interested students and faculty here that need and want to use imaging technologies to address interesting and important questions.”
First-round projects include the engineering of a new “molecular imaging” MRI contrast agent for detecting early calcification of the aortic valve; the combination of ultrasound and MR data to evaluate the elastic properties of tissues, which are associated with pathological indicators of disease; a clinical decision support system for patient-specific cancer diagnosis and management; and ultrasound-guided delivery of chemotherapy drug-laden nanoparticles to metastasized lung cancer cells in the brain. Applications for second-round projects are now underway.
All projects involve at least one principal investigator from each of the partnering institutions, who jointly advise a doctoral student on a project that could positively impact clinical practice. Participating ENG faculty include Professors Joyce Wong (BME, MSE), Paul Barbone (ME, MSE), Venkatesh Saligrama (ECE, SE) and Yannis Paschalidis (ECE, SE); Associate Professor Porter; and Assistant Professor Roblyer.
“The fields of biomedical imaging and bioengineering have been converging and collaborating for decades, and that collaboration continues to get closer and closer,” said Seltzer, noting a burgeoning clinical need for advanced technologies in functional and molecular imaging; information technologies ranging from data mining to image processing; and minimally-invasive diagnostic and therapeutic procedures guided by high-technology imaging techniques.
As a Senior Member, Klamkin has the ability to hold executive IEEE positions and serve as a reference for other applicants for senior membership. In order to eligible to be nominated or apply one must have shown significant performance in at least five years in professional practice.
Klamkin’s research is focused on integrated photonic technologies for optical communications, microwave photonics, and sensing. “The photonic devices and integrated circuits that we develop in the Integrated Photonics Group increase the capacity of fiber-optic networks, enable more efficient communication between and inside data centers, and could revolutionize space communications.”
He felt honored to be recognized as Senior Member of the IEEE. “The IEEE is one of the most recognized professional associations and produces publications and technology standards that strongly influence the field in which I am active.”
Since March 2013, Klamkin has been an Assistant Professor at Boston University. He then received Boston University College of Engineering Dean’s Catalyst Award. Some of his research interests include: integrated photonics, compound semiconductors, and microwave photonics.

Cultivating Excellence, Transforming Society
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.
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.”

Recognized for Wearable Fitness Tracking Device
By Chelsea Hermond (SMG’15), ECE, and Mark Dwortzan
Energized by New Year’s resolutions of spending more time in the gym, more and more of us are using apps and equipment to help track our progress. Jawbone and Nike Fuel Band are among the wearable products on the market designed to do just that, but there’s a growing demand for more customizable fitness tracking devices.
That’s the idea behind Atlas, an Austin, Texas-based company founded by Mike Kasparian (ECE ’12, MS’13) and his preschool friend, Peter Li. The Atlas Wristband tracks and identifies exercises, counts reps and sets, detects heartrate, calculates burned calories and evaluates form. It also displays workouts live and is compatible with many popular fitness apps such as MapMyFitness and Fitocracy.
Now the idea has won accolades from the editors of a major business magazine: Forbes has named the company’s 25-year-old cofounders in its 2015 “30 Under 30: Consumer Tech” listing. Their entry reads: “Atlas cofounders Peter Li and Michael Kasparian both wanted to find a better way to keep track of their workouts so they teamed up to create a wearable with 3D body tracking and advanced data analytics. Atlas launched on Indigogo at the beginning of 2014, and has raised $1.2 million in investment capital.”
“I’m very honored and excited to be a part of such an elite group of young professionals,” said Kasparian, who learned of his inclusion in theForbes list while in China overseeing assembly and production of the company’s first production prototypes. “I couldn’t have gotten to where I am today without the experiences and mentors I had at BU, and the team chemistry between myself and Peter.”
To identify a user’s exercises ranging from bicep curls to pushups, Atlas combines motion sensors and advanced machine learning algorithms with an exercise motion database, enabling comparisons between the user’s form and a library of perfect form reference exercises. For each exercise it identifies, the device counts the numbers of reps completed per workout and tracks the user’s progress over time through a mobile and web app.
Li, the company’s CEO, initially came up with the idea while developing a program for people at Johns Hopkins University to lose weight and gain muscle mass. He contacted Kasparian, then designing circuits for defibrillators at Philips Healthcare, to help with the hardware and start exploring a business strategy. Techstars, a startup accelerator in Austin, provided them with office space, funding and mentorship. Kasparian now serves as Atlas’s chief technology officer.
“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,” said Adjunct Professor Bakak Kia (ECE), who advised Kasparian during his senior design project, which garnered the top team prize, the P. T. Hsu Memorial Award for Outstanding Senior Design Project, and an individual honor for Kasparian, the Michael F. Ruane Award for Excellence in Senior Capstone Design. For his Master of Science research project, Kasparian designed the hardware platform that would ultimately be used in the Atlas Wristband.
The company’s first batch of production-quality Atlas Wristbands will be delivered to early backers in April 2015, and orders are now being taken for its third batch, which will be shipped this summer.
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.”

Recognizing senior and junior faculty for major contributions to their fields and to society at large, the College of Engineering has bestowed its annual Distinguished Scholar Award on Professor Christos Cassandras (ECE, SE), and its annual Early Career Excellence Award on Assistant Professor Xue Han (BME).
The Distinguished Scholar Award honors senior faculty members who have helped move their field and society forward through outstanding, high-impact research, and provides the recipient with a public forum to discuss his or her work before the Boston University academic community. The Early Career Research Excellence Award celebrates the significant, recent, high-impact research achievements of exemplary tenure-track faculty who are within 10 years of receiving their PhD.
In conjunction with his award, Cassandras will deliver a public lecture, “Complexity Made Simple (at a Small Price),” on March 19 at 4 p.m. in the Photonics Center Auditorium (room 206). Cassandras plans to highlight methods he’s developed to solve difficult problems by exploiting their specific structure, asking the “right” questions and challenging some conventional engineering approaches — and show how these methods have resulted in energy savings, enhanced security and other benefits.
Distinguished Scholar Award
The Distinguished Scholar Award recognizes Cassandras as “one of the pioneers of an emerging field, discrete event dynamical systems, that is used extensively in the modeling, analysis and design of dynamical systems in diverse applications such as manufacturing systems, communications, transportation networks and cyber-physical systems,” said Electrical and Computer Engineering Chair and Professor David Castañón.
“I am honored to be selected as the 2014 College of Engineering Distinguished Lecturer,” said Cassandras, who also specializes in hybrid systems, stochastic optimization and computer simulation. “I have always enjoyed research which involves new, relatively unexplored areas and unusual ways to tackle ‘real world’ problems, from contributing to the establishment of the field of discrete event dynamic systems to envisioning new ways to design and manage complex systems such as ‘smart cities.’”
A member of the BU faculty since 1996, head of the College’s Division of Systems Engineering and cofounder of BU’s Center for Information and Systems Engineering (CISE), Cassandras has published five books and more than 300 refereed papers. He was editor-in-chief of the IEEE Transactions on Automatic Control from 1998 through 2009, and the 2012 president of the IEEE Control Systems Society (CSS). He has chaired several technical conferences and served as plenary speaker at various international conferences, including the American Control Conference in 2001 and the IEEE Conference on Decision and Control in 2002, and Distinguished Lecturer for the CSS.
Cassandras’s numerous awards include a 2012 Kern Fellowship, a 2011 prize for the IBM/IEEE Smarter Planet Challenge competition, the 2011 IEEE Control Systems Technology Award, the Distinguished Member Award of the IEEE Control Systems Society (2006), the 1999 Harold Chestnut Prize (International Federation of Automatic Control (IFAC) Best Control Engineering Textbook) for Discrete Event Systems: Modeling and Performance Analysis, and a 1991 Lilly Fellowship. He is also a Fellow of the IEEE and IFAC.
Early Career Research Excellence Award
A member of the BU faculty since 2010, Han develops and applies high-precision genetic, molecular, optical and electrical tools and other nanotechnologies to study neural circuits in the brain. By using these novel neurotechnologies to control and monitor a selected population of brain cells, she and her research team seek to identify connections between neural circuit dynamics and behavioral pathologies. Establishing such connections could improve our understanding of neurological and psychiatric diseases, and lead to new treatments.
In recognition of her innovative research on developing novel neurotechnologies using light sensitive nanoparticles to sense neurons’ cellular environment and to deliver drugs directly to the brain, Han was named by President Obama in January as one of 102 recipients of the Presidential Early Career Award for Scientists and Engineers, the highest honor bestowed by the US government on science and engineering researchers in the early stages of their careers. Han has also received a National Institutes of Health (NIH) Director’s New Innovator Award and recognition as a Pew Scholar in the Biomedical Sciences, Sloan Research Fellow and Peter Paul Fellow.
“We are delighted that the College of Engineering has chosen to celebrate Xue’s remarkable achievements with this award, and I can think of no one more deserving,” said Professor Sol Eisenberg, who heads the BME Department.
