Dr. Howie Huang (ECE) and his PhD student Isaiah King are developing a unique visual search engine called Graggle, envisioned as the “Google Scholar for COVID-19 Research.” Graggle uses powerful graph representation and machine learning techniques to capture complex contextual relationships between different documents. It is purposely built for an open research dataset, prepared by the White House, NIH, and a consortium of medical research organizations, which consists of over 130,000 scholarly articles that were written about COVID-19 and the related coronavirus. Graggle provides researchers worldwide with faster, more informative access to knowledge that they can explore visually.

The National Science Foundation has produced a video highlighting the plasma brush research that Dr. Michael Keidar (MAE) is conducting to sterilize medical and personal protective equipment. As previously reported, Dr. Keidar received an NSF RAPID grant for this project.
DARPA Habitus Program has awarded Dr. Aylin Caliskan (CS) a 42-month, $330,000 grant to generate self-sustaining artificial intelligence models in low-resource languages that can automatically convert implicit collective associations and information to explicit knowledge. This grant was awarded as part of a large project with her collaborators from Raytheon BBN and Tufts University.
Dr. Mahdi Imani (ECE) has received a two-year, $175,000 CRII grant from the National Science Foundation’s Directorate for Computer and Information Science and Engineering (CISE) for his project “Informative Bayesian Learning and Data Gathering Through Expert-Acquired Data.” The project aims to advance the state-of-the-art in learning and data gathering processes, and contribute to the science base of machine learning, control/learning theory, and Bayesian statistics. The overarching goal of the project is development of tools to enable optimal incorporation of user information during the learning process, as well as learning from multiple data sources acquired by non-similar users/experts.
Drs. Saniya LeBlanc (MAE), Payman Dehghanian (ECE), and Ekundayo Shittu (EMSE) have received a two-year, $499,967 grant from the U.S. Department of Energy's Office of Energy Efficiency & Renewable Energy, Advanced Manufacturing Office. Dr. LeBlanc is the lead PI. For the project titled “Urban Combined Heat and Power with Integrated Renewables and Energy Storage,” the research team will partner with the GW Office of Sustainability to analyze GW's urban district energy system. The team will investigate the impact that combined heat and power, renewable electricity generation, and electricity and thermal storage have on the cost, reliability, and resilience of community energy systems that span multiple buildings. The project results will allow urban facilities and organizations to measure the value of resiliency benefits from new energy technologies and integrate that value into their investment decision-making activities.
Dr. Yongsheng Leng (MAE) has received a three-year, $326,429 National Science Foundation grant for the project “Computational Simulation and Cyber Software Development for Nanoscale Friction.” Dr. Leng will use this award to develop a new computational modeling and simulation tool to enable a deeper understanding of nanoscale friction dynamics to enable more efficient advanced manufacturing processes and high-performance nanoscale machines and systems.

Louri. “Agile: A Learning-enabled Power and Performance-Efficient Network-on-Chip Design,” IEEE Transactions on Emerging Topics in Computing, DOI: 10.1109/TETC.2020.3003496, June 2020. The work exploits the use of reinforcement learning and presents an application-aware, low-power, and high-performance Network-on-Chip design for future parallel computing chips. The research published in both papers is funded by a grant from the National Science Foundation.

The 2020 issue of Synergy magazine is now available both in web format and as a PDF. The magazine was written prior to the outbreak of the COVID-19 pandemic and was prepared for hard copy distribution. However, the decision was made later to publish the magazine digitally instead, after the end of the spring semester, so some information in this issue of Synergy reflects the status of activities at SEAS just prior to the outbreak of the COVID-19 pandemic in the spring.
EMSE PhD candidate Deniz Marti successfully defended her dissertation virtually on June 25. Her dissertation, titled “Investigating Expertise Transfer and the Experts’ Cognitive Decision-making Processes in Socio-technical Systems,” was supervised by Dr. David Broniatowski (EMSE) and Dr. Thomas Mazzuchi (EMSE).
