Collaborative project highlighted in premier neuroscience journal

The February issue of the journal Neuron features a cover story highlighting the joint work between Professors Arto Nurmikko and Barry Connors. Neuron is a premier journal in Neuroscience.

This is another illustration of the collaboration between Engineering and Biology and Medicine here at Brown. Arto Nurmikko's group has successfully led the initiative to bring the ‘optogenetics’ methodology to Brown.

Prof. Webster and Erik Taylor's implant research highlighted

PROVIDENCE, R.I. (Ivanhoe Newswire) -- Almost 1 million people go under the knife every year for a knee, hip or shoulder replacement. Surgeons say those metal implants can become playgrounds for bacteria, leading to potentially deadly infections like MRSA. It happens to nearly 20,000 people every year. One scientist has developed a tiny solution that could kill the infection without removing the implant.

Dr. Webster is creating a nano-sized solution to fight implant infections. He manufactured iron-oxide nanoparticles -- tiny warriors that zero in on the implant, penetrate the bacterial shield, and kill the bacteria. In lab tests, an injection of the specially-designed nanoparticles eliminated 74 percent of the bacteria on an implant in 48 hours. When repeated three times over six days, the nanoparticles killed 100  percent of the bacteria.

NSF Career Awards to Dworak and Reda

Two young faculty members in the Division join the ranks of our faculty that have been awarded the NSF CAREER Awards, Jennifer Dworak and Sherief Reda. The Faculty Early Career Development (CAREER) Program is a Foundation-wide activity that offers the National Science Foundation's most prestigious awards in support of the early career-development activities of those teacher-scholars who most effectively integrate research and education within the context of the mission of their organization.

Enhancing Quality through Probabilistic On-Chip Test
Jennifer Dworak

Future integrated circuits will contain tens, hundreds, or possibly even a thousand cores per chip. However, the scaling techniques that will make this possible also make the underlying circuit fabric less reliable—leading to increased wearout and defects that cannot be detected at manufacturing. In response, the PI proposes fundamental research for generating new test sets on-chip to identify failing cores. The tests will be created “on-the-fly” and dynamically targeted to the most critical areas of a core. Some key portions of the proposed research involve the creation and verification of hardware monitors for determining which faults are most important for the user’s applications, the diagnostic use of online error detection hardware to pinpoint locations that caused previous failures, and the analysis and development of protocols to efficiently create and transport tests in a network-on-chip environment.

The great performance advantages of future multi-core devices will remain unrealized if the reliability of those devices cannot be trusted. The proposed research investigates critical tools for promoting that reliability. The integrated education plan provides research opportunities for students at multiple levels—from high school to graduate school—including students from underrepresented groups. In addition to recruiting undergraduates from Brown, the PI plans to work with the CRA-W DREU (Distributed Research Experiences for Undergraduates) program to host visiting female undergraduates for summer research. The PI will also recruit high school students from the Providence Public Schools, many of whom are members of underrepresented groups, for summer research through the Brown GK-12 program.

Transcending the Thermal Management Challenges of Tera-Scale Computing

Sherief Reda

Elevated temperature is a major problem for the reliability, performance, power consumption, and packaging costs of integrated electronic devices.

Temperature is a main physical barrier limiting the performance benefits of future technologies that promise tera-scale integration. To meet the thermal management challenges of future many-core processors, this research program envisions a new class of intelligent dynamic thermal management systems that explore the vast search space of possible control parameter settings and decide the optimal temperature and performance targets. This research program also investigates new cooling system designs that enable the thermal management system to target directly hot spots at the micro scale. Directly targeting hot spots alleviates the thermal constraints on performance.

The proposed research program will lead to transformative solutions and tools that address the fundamental thermal management challenges of computing systems and ensure their scalability. The proposed program will lead to the training of a diverse workforce of undergraduate and graduate students to be well prepared to deal with tomorrow’s thermal management challenges. The educational component of this program includes (1) research experiences for undergraduates; (2) integrated approach to entrepreneurship education with research; (3) hands-on training through the development of educational laboratories based on a state-of-the-art infrared camera; and (4) continuous education through the development of high-quality educational materials and an interactive technical Web site.

The purpose of the work is to limit infection of endotracheal tubes.

Professor Franck studies cellular movement

Our cells are more like us than we may think. They’re sensitive to their environment, poking and prodding deliberately at their surroundings with hand-like feelers and chemical signals as they decide whether and where to move. Such caution serves us well but has vexed engineers who seek to create synthetic tissue, heart valves, implants and other devices that the human body will accept.

To overcome that obstacle, scientists have sought to learn more about how cells explore what’s around them. While numerous studies have looked at cellular movement in two dimensions and a few recent experiments involved cellular motion in three dimensions, scientists remained unsure just how much cells interacted with their surroundings. Now, a study involving Brown University and the California Institute of Technology has recorded for the first time how cells move in three dimensions by measuring the force exerted by cells on their environs. The research gives scientists their most complete assessment to date about how cells move.

Graduate Student Profiles

In an effort to highlight the remarkable graduate student research here at Brown Engineering, we are creating a series of profiles that will highlight their work. Below are previews, to see the full profile details, click here."The catchphrase of our lab is “Atoms to Autos,” which means that we work on incorporating basic scientific research that begins at the atomic scale into larger and larger scale models eventually making improvements to the design of new GM automobiles."

"My research interests concern the exploration of multiprocessing techniques for low-power embedded systems (like smartphones, game consoles, etc.), and the development of design methods to improve the yield of 3D integrated circuits."

"BrainGate2 is an investigational device that we hope will one day enable people with paralysis to control external devices, such as a computer cursor, simply by mentally attempting the motion, essentially turning thought into action."

"Lead is added to Sn solder in electronic devices to inhibit defects (called “whiskers”) which result in failures and a shorter product life. I’m trying to understand how lead prevents defects and to find an environmentally friendly replacement that works equally well."

"The end goal of the influenza project is to develop a small, low cost, sensitive microfluidic assay to detect the presence and type of influenza in patient samples. Ideally, this device would integrated several tasks normally done in a laboratory such that it could be used at the point of care."

Undergraduate Research Profiles

Sharon Makava started at Brown as an engineer with health-related interests. Her initial interests led her to biomedical engineering, but she is now pursuing Chemical and Biochemical Engineering degree. Her interactions with her former concentration advisor, Professor Tripathi, led her to her current work in his lab. She is working on K103N mutation in the HIV virus with graduate student Kenny Morabito. They are working to isolate and amplify the mutation at low sample concentrations. The end goal is to develop a test diagnostic which will allow doctors to look for a drug resistance amongst their patients. Her current research will give her a strong foundation to pursue industry or academic directions in the future, but for now she says “she can’t imagine being anywhere else.”
Eli Fine understands the importance of being aware of your intentions when you speak. He gained this appreciation through a linguistics class he took as part of Brown's open curriculum elective options. He has not only gained a greater appreciation for the scientific world, but also anthropology, philosophy, psychology, and linguistics. His collaborative spirit fits well with the interdisciplinary group of mathematicians, engineers and biologists he researches with in his multiple research projects at Brown.
Carmichael Ong is an intricate mix of biologist, biochemist, and bioengineer. He has the network to prove it. Carmichael has worked on two large interdisciplinary research projects at Brown in his undergraduate career. He believes that the intimate atmosphere within Brown Engineering and the approachable faculty are major benefits to his future. He plans to continue as a researcher in his future career either in industry or academia. Regardless of which direction he chooses, he will understand how to network with top rate researchers in an interdisciplinary setting because of his experience at Brown.
Ben Howard understands what it would take to be a Mythbuster on the Discovery Channel. He understands engineering and science principles and appreciates photography and video production. As a cinematographer for BTV (Brown’s Television Station) he produces his own tv show. Beyond just being inspired to record the world around him in unique ways, Ben is a design-oriented engineer. He found his way to Professor Breuer’s lab after having him for Thermodynamics class. His summer work extended into a larger research project to create a prototype that can create liquid droplets out of oil – a humidifier of sorts for oil. In Breuer’s lab, they have learned to use photography to study the aerodynamics of bat flight. They can record two flash photographs and record the velocity based on the distance the droplets have traveled around the bat’s wings. Most of the science is stumped on how bats accomplish their flight patterns. The Mythbusters wouldn’t even be able to figure it out, but Ben and other Brown engineers will eventually.
Juri Minxha works at the interface between engineering and neuroscience. He came to Brown uncertain of what he hoped to accomplish during his four years here. He found that the introductory engineering courses gave him a chance to test drive all of the related engineering fields. He also used the open curriculum to his advantage and took neuroscience courses. This background led him to Professor Palmore’s lab where he works at the interface of electrical engineering and neuroscience. He understands the importance of this research and hopes to continue his scholarship in a graduate program.

Many of our students are awarded annually with Halpin awards for their interdisciplinary research. To read more about the Halpin awards and the students profiled, click here.

Childhood asthma is at near epidemic proportions in parts of New York City, affecting as many as one quarter of all elementary aged children in certain under-served minority neighborhoods of the city. There is also an increasing body of evidence indicating that living near to traffic is associated with increased respiratory problems in children. Exposure to fine particles from diesel vehicles is suspected as a likely causal agent in these associations between traffic and asthma, but there is only limited information relating personal exposures to diesel particles and health for individual children. This seminar introduces both the asthma problem in New York City and the recent evidence regarding asthma and diesel air pollution, and then presents recent in-press results of a study conducted by NYU in the South Bronx that has directly tested the relationship between childhood asthma symptoms and personal exposures to diesel particles. Options available to control diesel emissions in New York City and elsewhere are also discussed.
