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?
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.

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.
Imagine two hiring managers sizing up an applicant. The first gathers all the information she can before forming a first impression. The second collects the bare minimum but does so strategically, arriving at virtually the same impression with far less effort and in far less time.
It turns out that the latter approach can be taken to produce reasonably accurate photos of objects under low lighting conditions using a remote sensing technology such as LIDAR, which bounces pulsed laser light off of a targeted object to form an image. Rather than waiting to collect and compare hundreds of reflected photons to generate each pixel of the image, as is typically done, you can instead count the number of laser pulses it takes to detect the first photon at each pixel. The lower the number, the greater the intensity of the light reflected off the object’s surface — and thus, the brighter the pixel.
Assistant Professor Vivek Goyal (ECE), who joined the College of Engineering faculty in January, and who, along with former colleagues at MIT’s Research Laboratory of Electronics, demonstrated the concept in a recent issue of the journal Science, calls his method “first-photon imaging.”
“The project started out as a thought experiment,” said Goyal, whose research was funded by the Defense Advanced Research Projects Agency’s (DARPA) Information in a Photon Program, and the National Science Foundation. “We wondered what we could infer about a scene from detecting only one photon from each pixel location, and eventually realized that when the intensity of light is very low, the amount of time until you detect the photon gives you information about the intensity of the light at each pixel.”
First-photon imaging may ultimately improve night vision and low-light remote sensing technologies by extending the distance at which images may be taken. The new method may also dramatically increase the speed of biological imaging and the variety of samples — many of which degrade when subjected to higher-intensity lighting — that can be photographed.
To produce a high-quality image from the raw, single-photon-per-pixel data, Goyal’s method applies a computer model of surfaces and edges typically encountered in three-dimensional, real-world objects, correcting the intensity and depth of neighboring pixels as needed to fit the model; and filters out noise coming from ambient light sources.
While many researchers are pursuing new techniques to boost remote sensing and microscopy capabilities, most focus on building more effective detectors. Goyal is working to significantly enhance existing detectors by incorporating accurate physical models in signal processing, and to further explore the potential impact of first-photon imaging on remote sensing and microscopy.
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.
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.

Boston University students have big ideas – whether they’re aiming to prevent cyber attacks or using GPS data to improve cattle herding. As good as their work is though, they don’t always know the best way to present their research.
Ph.D. students, Yasaman Khazaeni, Greg Castanon, and Jing Wang, initially came up with the idea for the event last semester and hoped it would give their classmates a chance to practice speaking in front of a large audience.
“One of the main issues we have as students becomes clear at conferences,” said Khazaeni. “We’ve done great research but don’t present it well.”
Often times, she added, engineering students come from international backgrounds and don’t have enough confidence to present in English.
“By speaking in front of a friendly audience, as opposed to a conference where you’d know few people in the audience, your classmates and professors can offer feedback and really help you smooth out your final presentation,” said Khazaeni.
Khazaeni, who helped choose 14 students to present out of a pool of 23 applicants, said that the event also allowed CISE students to learn from classmates and discover more about the projects they’ve been working on.
Among those she learned from were Ph.D. students, Morteza Hashemi and Delaram Motamedvaziri, who took home the Best CISE Presenter awards.
Hashemi, who is advised by Professor Ari Trachtenberg (ECE, SE), spoke about his project, Coded Data Sharing in Intra-Car Wireless Sensor Networks. He has been working with Trachtenberg, Professor David Starobinski (ECE, SE), Ph.D. student, Wei Si, and General Motors Research to determine if using wireless sensor networks (WSN) might allow for a greener way to construct tomorrow’s vehicles. The work previously won the Center for Reliable Information Systems and Cybersecurity Award as well as the Provost’s Award at Scholars Day last year.
Advised by Professor Venkatesh Saligrama (ECE, SE), Motamedvaziri spoke about her work, “Poisson Statistics and the Future of Internet Marketing.”
“The effectiveness of search engine marketing is dropping while the power of social media marketing is rising,” she explained. “Mathematics would suggest that social media is now the better advertising strategy.”
She said that though her research focused on total hits advertisements received, she’d like to expand her work in the future by looking at data concerning how long a person stayed on a website.
“Ultimately, we’re more interested in seeing transactions occur as opposed to clicks,” said Motamedvaziri.
Also honored at a reception at the BU Castle following the presentations were Setareh Ariafar, the Most Attentive CISE Student, and Professor David Castañón (ECE, SE), awarded for his contributions to CISE. Because 20 students attended all fourteen presentations, the most attentive of them was chosen by raffle.
In case any students left the workshop having doubts about their speaking skills, Professor Christos Cassandras (ECE, SE) closed the day by offering some advice, including “never overestimate the intelligence of your audience” and “the maximum pieces of information that should appear on a slide is two.”
“Giving a good talk is a difficult thing,” he said. “It’s as much of an art as a science.”

When Connor McEwen (ECE ’14) learned about Refresh, an energy-efficient vending machine designed by recent alums from the Massachusetts Institute of Technology and Rhode Island School of Design, he knew this was an idea that showed potential and wanted to invest in it.
Not too many undergraduates have the ability to make a difference in getting a startup off the ground financially, but McEwen isn’t just any student. He’s one of the investment decision makers for the Dorm Room Fund.
The Dorm Room Fund, a student-run venture fund supported solely by Philadelphia-based First Round Capital, allows entrepreneurial students to have $500,000 to use toward investing in student startups over a two-year period. The program has roots in New York, Philadelphia, and Silicon Valley and came to Boston last fall, where members hope to invest in about 25 companies by 2015.
McEwen, who has been passionate about technology all of his life, was one of 11 students chosen to work with the Dorm Room Fund’s inaugural Boston group, who meet weekly at the Cambridge Innovation Center.
When it comes to investment strategy, McEwen said: “I personally am most interested in student-led tech startups that have the potential to really solve a problem and impact how we live our lives. Since our goal is to help students build their companies, I also like companies where I can understand and use the product and therefore help the most.”
McEwen, who is also a member of the BU Entrepreneurship club and runs a BU Startups newsletter, first became interested in entrepreneurship during his freshman year, thanks to his roommate, Nam Chu Hoai (CS ’14), who had previously worked at a startup.
“We started reading about them on a few websites, discussing companies, and working on an idea ourselves,” McEwen said.
He even took a year off to work on that project, Credport. Though he and Chu Hoai eventually realized that the market didn’t need their product, they learned a lot and McEwen called the time “a great experience.”
Today, when McEwen’s not working on the Dorm Room Fund, he’s back at Boston University working on his senior design project. He teamed up with biomedical engineering students in Assistant Professor Ahmad Khalil’s lab to design an LED device that will help improve synthetic biology experiments.
“Our device basically shines an LED light on a well plate, an enclosure holding a bunch of different cell samples, for a programmable duration, which will enable researchers in optogenetics and synthetic biology to run better experiments more efficiently and accurately,” said McEwen.
As a senior design mentor, Khalil has noticed that McEwen has shown great passion when applying his strong technological background toward his research.
“He brings infectious enthusiasm and wonderful ideas to the lab and is never reluctant to seek advice from my graduate students and me,” said Khalil.
Though McEwen initially thought about working on a startup-related project for senior design, he decided instead to focus his research on something he could only do at BU. Through this project, he’s able to utilize his own background in computer engineering and also work with students majoring in electrical, mechanical, and biomedical engineering.
That being said, his long-term focus remains the same. He doesn’t know exactly where he’ll be when he graduates this spring but he’s confident he’ll be working with a startup.

Karl, Moustakas and Paschalidis Recognized for Outstanding Achievements
Professors W. Clem Karl (ECE, BME, SE), Theodore Moustakas (ECE, MSE) and Yannis Paschalidis (ECE, SE) have been named as 2014 IEEE Fellows, the highest grade of membership in the world’s leading professional association for advancing technology for the benefit of society.
The IEEE confers the grade of Fellow upon individuals with outstanding records of accomplishment in any of the organization’s fields of interest, which range from aerospace systems, computers and telecommunications to biomedical engineering, electric power and consumer electronics. Less than 0.1 percent of voting members — the IEEE currently has 400,000 members in 160 countries — are selected annually for this member grade elevation, considered a major career achievement and prestigious honor across the technical community.
W. Clem Karl
Karl was recognized for his contributions to “statistical signal processing and image reconstruction.” He has developed several statistical models for the extraction of information from diverse data sources in the presence of uncertainty, and applied them in projects that include automatic target detection and recognition for synthetic aperture radar; locating oil deposits and analyzing the earth’s atmosphere; and monitoring medical conditions using tomography and MRI.
“This is a great honor, and I’m humbled that my peers would confer it on me,” said Karl.
A member of the BU faculty since 1995, Karl has assumed many leadership roles for the IEEE. Currently editor-in-chief of IEEE Transactions on Image Processing, he is a member of the Board of Governors and Conference Board of the Signal Processing Society; the Transactions on Medical Imaging Steering Committee; the Biomedical Image and Signal Processing Technical Committee; and the Technical Committee Review Board. He has co-organized IEEE workshops on statistical signal processing and bioinformatics, and was general chair of the 2009 IEEE International Symposium on Biomedical Imaging.
Among other things, Karl is developing methods to improve the detection of explosives in luggage. The technology could increase passenger safety while reducing delays and other inconveniences for air travelers, such as having to remove laptops and other electronic devices from bags.
Moustakas was recognized for his contributions to “the epitaxial growth of nitride semiconductors.” He is a trailblazer in molecular beam epitaxy, a versatile and advanced thin-film growth technique used to make high-precision, nitride (nitrogen compound-based) semiconductor materials used in fiber-optic, cellular, satellite and other applications.
His most notable achievements include pioneering the nucleation steps for the growth of gallium nitride on sapphire and other substrates, an essential process for the manufacture of blue LEDs, which are widely used in solid state lighting applications; and developing highly-efficient, deep ultraviolet (UV) LEDs, which are expected to provide environmentally friendly water and air purification.
“I am delighted to receive this prestigious award and I am very grateful to many of my collaborators at BU and other institutions, as well the outstanding past and current students that I have had the fortune of mentoring,” said Moustakas.
A member of the ENG faculty for more than 30 years and ENG Distinguished Scholar who helped shape the Materials Science & Engineering Division, Moustakas has had a broad impact on his field, through 25 patents, hundreds of invited talks and journal papers and 10,000 citations in research literature. Recently selected as the recipient of the Molecular Beam Epitaxy (MBE) Innovator Award, he is also a Fellow of the American Physical Society and Electrochemical Society, and Charter Fellow of the National Academy of Inventors. In 2013 he was named the Boston University Innovator of the Year.
Moustakas is currently working to create visible and UV LEDs and lasers for solid-state white lighting, water and air sterilization, and identification of biological and chemical agents; investigating indium gallium nitride “quantum dots” that boost solar cell efficiency; and, in collaboration with Associate Professor Roberto Paiella (ECE, MSE), studying the use of nitride semiconductor structures for green LED applications and for emitters and detectors operating in the far infrared.
Paschalidis was recognized for his contributions to “the control and optimization of communication and sensor networks, manufacturing systems and biological systems.” Since joining the College of Engineering faculty in 1996, he has developed sophisticated algorithms for everything from a homeland security early warning sensor network to a next-generation electronic healthcare management system.
“I am elated to have been named an IEEE Fellow,” said Paschalidis. “Much credit is due to all my students and postdoctoral associates, past and present, who have contributed to the work being recognized, and all my collaborators, many of them here at Boston University.”
Co-director of the College’s Center for Information and Systems Engineering (CISE), an ENG Distinguished Faculty Fellow and affiliate of the BioMolecular Engineering Research Center, Paschalidis has a diverse research portfolio that spans the fields of systems and control, networking, applied probability, optimization, operations research, computational biology and bioinformatics. His work has resulted in new applications in communication and sensor networks, protein docking, logistics, cyber-security, robotics, the smart grid and finance.
Paschalidis has received several honors, including a CAREER award from the National Science Foundation, an invitation to participate in the National Academy of Engineering Frontiers of Engineering Symposium, two best paper awards, and best performance at a computational biology competition. He is the editor-in-chief of the IEEE Transactions on Control of Network Systems and a member of the Board of Governors of the IEEE Control Systems Society.
Visiting Professor Vivek Goyal (ECE), who will be an assistant professor in the ECE Department starting in January, was also named an IEEE Fellow.
Dedicated to the advancement of technology, the IEEE publishes 30 percent of the world’s literature in the electrical and electronics engineering and computer science fields, and has developed more than 900 active industry standards. The association also sponsors or co-sponsors nearly 400 international technical conferences each year.
In a ceremony held October 25 at the Boston University Photonics Center, the College of Engineering celebrated its alumni and announced the 2013 Distinguished Alumni Awards. Presented by Dean Kenneth R. Lutchen following a buffet dinner and champagne toast, the awards recognize individuals who have made significant contributions to their alma mater, community and profession. Lutchen commended the recipients for bringing honor to the College through their careers, commitment to the highest standards of excellence, and devotion to the College.
Anton Papp (EE ’90), vice president for Corporate Development at Teradata, received the Service to Alma Mater award, which honors alumni who have enhanced the College of Engineering’s stature through voluntary service to BU.
At Teradata Papp oversees, evaluates and executes investments, mergers and acquisitions, and strategy. Prior to joining Teradata, he served as vice president of Corporate Development & Global Alliances at Aprimo and held numerous investment banking positions. A graduate of the prestigious US Navy Fighter Weapons School (TOPGUN), Papp attended BU on a Naval ROTC scholarship and served as a Naval Officer and F-14 Tomcat Flight Instructor. He also earned an MBA in Finance from Columbia Business School.
Papp serves on the College of Engineering Dean’s Advisory Board, the ENG West Coast Alumni Leadership Council, and the BU West Coast Regional Campaign Committee. He has been the leading supporter for the ENG/SMG Summer Leadership Institute program, and part of the College’s efforts to recruit top undergraduates.
Dan Ryan and Aaron Ganick (both ECE ’10), cofounders of the telecommunications company ByteLight, received the Distinguished Young Alumni award, which honors outstanding alumni within 10 years of graduation for outstanding service to their profession or community.
A startup that emerged out of the Smart Lighting Engineering Research Center at BU, ByteLight has produced a system that’s similar to an indoor GPS. Special LED lights provided by Bytelight enable your smartphone to determine your location and to bring up location-based information ranging from store coupons to museum exhibit descriptions.
George Savage (BME ’81), Chief Medical Officer and cofounder of Proteus Digital Health, and a member of the BU College of Engineering West Coast Advisory Council, received the Service to the Profession award, which honors alumni whose work has significantly contributed to the advancement of their profession and brought them recognition within their field.
Savage has started 10 companies since 1989 as entrepreneur or founding investor, including FemRx (acquired by Johnson and Johnson), CardioRhythm (acquired by Medtronic) and QRx Pharmaceuticals. He holds an M.D. from Tufts University School of Medicine and an M.B.A. from Stanford University Graduate School of Business, and serves on the boards of Menlo Healthcare Ministry, the Pacific Research Institute and Silent Cal Productions.
At Proteus, Savage has advanced a system of small, ingestible event markers that are implanted in a patient’s medications. A monitor worn as a patch on the patient identifies each pill upon swallowing and tracks vital signs, which are uploaded to the patient’s mobile phone and transmitted to caregivers and healthcare professionals. The system allows for instantaneous and personalized treatment and promises to transform the way doctors monitor patients’ medicine.
Over the last few weeks, nearly 20 million Americans tried accessing a broken United States health care site that couldn’t handle the traffic, among other problems. And even if you weren’t one of the many applying for health coverage, you’ve probably experienced network congestion at some point.
Typically, network congestion occurs if a link or node is carrying too much data; as a result, the quality of service drops. The most severe form of communication disruption is deadlocks. A deadlock happens when several messages mutually block each other so that their delivery is not just delayed but stopped permanently.
“This is a long-standing problem, which is practically important and theoretically challenging,” said Distinguished Professor Lev Levitin (ECE, SE). “It has been attracting the efforts of many researchers for decades.”
Professors Levitin and Mark Karpovsky (ECE) have been working with their students on this problem for several years, developing new algorithms, specifically turn prohibition algorithms, to help direct data and essentially prevent information from being stuck in a deadlock as it travels through communication networks. This work covered a lot of ground by establishing lower and upper bounds for an optimal solution, outlining their discovery of a new class of algorithms, and developing a few algorithms that could actually solve the initial optimization problem.
The last advance on this project was achieved this year by Levitin and his team – ECE alum, Ye Wu (MEng ’13), and Visiting Scholar, Mehmet Mustafa. They have been working on developing new algorithms, specifically turn prohibition algorithms, to help direct data and essentially prevent information from being stuck in a deadlock as it travels through communication networks.
“Without changing the topology of existing networks, we managed to improve saturation points so that congestion is less likely to happen and latency is reduced which means lower waiting time for users,” said Wu.
The team recently presented their work at OPNETWORK 2013, a conference that focused on advancing the state of application and network performance management. Impressed by their research, “A Study of Modified Turn Prohibition Algorithms for Deadlock Prevention in Networks,” the judges awarded them Best Technical Paper.
“Computer experiments, executed earlier and in the latest work by Ye Wu and other students under the guidance of Dr. Mustafa, clearly showed the superior performance of our algorithms versus different algorithms suggested by other research groups,” said Levitin. He went on to add that the majority of publications in the field are on ad hoc algorithms as opposed to the “tree-free” algorithms he and his team explored.
The work gave Wu a chance to travel to Washington, D.C., and deliver the presentation at the Ronald Reagan Building and International Trade Center.
“I met some really nice students and professors from different countries who were happy to talk about their research,” said Wu. “The audience, I think, was also smart enough to understand the key points of our project and asked really good questions.”
Now a Boston University graduate, Wu looks back at his professor fondly, describing Levitin as open-minded, even when his student was questioning his own theories.
“Professor Levitin is the best professor I’ve ever known,” said Wu. “Even when we had no idea how to begin a project, he’d point us in the right direction.”
