EECS Assistant Prof. Sophia Shao, Associate Prof. Prabal Dutta, and alumnus Deepak Pathak have won 2022 Okawa Foundation Research Grants. The Okawa Foundation for Information and Telecommunications recognizes "studies and analyses in the fields of information and telecommunications." Shao, whose research interests are in computer architecture, was awarded for her work on building domain-specific systems at scale. Dutta, whose research interests include energy-efficient cyber-physical systems and applications of sensor networks and Internet-of-things technology, was awarded for his work on a new kind of radio architecture, called “backsplatter,” and combining it with conventional radios. Pathak, who is now an Assistant Professor of Computer Science at Carnegie Mellon University, was recognized for his work “Towards Continually Improving Robots in the Wild.” They comprise three of the seven U.S. recipients who were awarded $10,000 grants this year.

Girish Pahwa has won the 2022 IEEE Electron Device Society (EDS) Early Career Award. Dr. Pahwa is an assistant professional researcher at Berkeley EECS and is currently the executive director of the Berkeley Device Modeling Center (BDMC), whose leadership includes EE Profs. Chenming Hu and Sayeef Salahuddin. His research interests include device modeling, simulation, and benchmarking of emerging nanoscale technologies. Awarded annually, the EDS Early Career Award recognizes and supports technical development within the EDS field of interest. Recipients are given a plaque and a check for $1,000 at the EDS Awards Dinner, held in conjunction with the international Electron Devices Meeting (IEDM), which will be held in San Francisco, CA this year.

An interdisciplinary team of industry and academic researchers led by EECS Prof. Alexandre Bayen has completed its most ambitious real-time traffic experiment to date. The project was led by the CIRCLES Consortium, an effort led by UC Berkeley and Vanderbilt University, involving collaborators from five universities and multiple government agencies. The experiment tested 100 partially automated vehicles in real traffic with the aim of improving overall traffic flow. Operating out of a massive control center designed to monitor one section of I-14 in Nashville, TN, the researchers used AI to build on existing adaptive cruise control systems to smooth phantom jams collaboratively. Their results show a positive energy impact. “Driving is very intuitive. If there’s a gap in front of you, you accelerate. If someone brakes, you slow down. But it turns out that this very normal reaction can lead to stop-and-go traffic and energy inefficiency,” said Prof. Bayen. “That’s precisely what AI technology is able to fix—it can direct the vehicle to things that are not intuitive to humans, but are overall more efficient.” 

CS Profs. Dawn Song and David Wagner have won the Association for Computing Machinery (ACM) Special Interest Group on Security, Audit and Control (SIGSAC) Test-of-Time Award. The 2011 paper titled, “Android Permissions Demystified,” by Felt, Chin, Hanna, Song and Wagner, was the first paper to examine real-world security issues in Android applications' use of permissions. The paper has been cited 1985 times and is still taught in graduate courses today. The award was presented at the ACM Conference on Computer and Communications Security (CCS), the flagship conference of the ACM SIGSAC, which took place in Los Angeles this year.

Theory Ph.D. student Fred Zhang (advisor: Jelani Nelson) has won the Best Student Paper Award at ACM-SIAM Symposium on Discrete Algorithms (SODA) 2023. The paper titled, “Online Prediction in Sub-linear Space'' was co-authored by Binghui Peng of Columbia University. The ACM-SIAM Symposium on Discrete Algorithms, or “SODA,” conference showcases “research topics related to design and analysis of efficient algorithms and data structures for discrete problems.” 

EECS Associate Prof. Prabal Dutta has won the 2022 ACM SenSys Test of Time Award. The paper by Dutta, Dawson-Haggerty (Ph.D. ‘14), Chen, Liang, and Terzis titled, “Design and Evaluation of a Versatile and Efficient Receiver-Initiated Link Layer for Low-Power Wireless,”  was recognized “for pioneering the use of synchronous transmissions in low-power protocols by exploiting their benefits at the MAC layer and pushing the limits of radio operation.” Established in 2014, the “ToTA” recognizes papers that are at least 10 years old and have demonstrated long-lasting impact on network embedded sensing system science and engineering. “It's a real testament that so much of the field traces its roots to Berkeley,” said Dutta.

A research team led by EE Prof. Boubacar Kanté has created a new type of semiconductor laser, accomplishing an elusive goal in the field of optics: the ability to emit a single mode of light while maintaining the ability to scale up in size and power. The team showed that a structured semiconductor device implementing what they call an “open-Dirac potential” functions as a perfect, scalable laser cavity. They demonstrate that the laser emits a consistent, single wavelength, regardless of the size of the cavity. “Increasing both size and power of a single-mode laser has been a challenge in optics since the first laser was built in 1960,” said Kanté. “Six decades later, we show that it is possible to achieve both these qualities in a laser. I consider this the most important paper my group has published to date.”

EECS Assistant Prof. Sophia Shao is among the 15 recipients of the Intel Rising Star Award this year. Awarded annually, the Intel Rising Star Award (RSA) program supports early-career faculty whose research is groundbreaking and demonstrates the potential to disrupt industries. Recipients are chosen for “innovative teaching methods and for increasing the participation of women and underrepresented minorities in computer science and engineering.” Prof. Shao’s research focuses on improving the scalability, efficiency, and programmability of heterogeneous platforms from edge devices to data centers. In collaboration with senior technical leaders at Intel, Prof. Shao plans to explore the intersection of architectural prototyping, algorithm development, and programming support for heterogeneous accelerators: “As we enter the golden age of computer architecture, there are tremendous opportunities to innovate across the stack in the hardware community. I'm excited to work with our students, faculty members, and industry collaborators to build novel systems together!" said Shao. 

The Bakar Institute of Digital Materials for the Planet (BIDMaP), led by Chemistry Prof. Omar M. Yaghi, brings together CS Profs. Christian Borgs, Joseph Gonzalez, Jennifer Listgarten, Jennifer Chayes, and Kathy Yelick, along with faculty from the Department of Chemistry and Statistics, respectively, to affect climate change by combining machine learning and chemistry. The institute aims to develop a new field of machine learning for experimental science, creating algorithms and designing platforms to optimize the discovery, development, and deployment of technology. “This is what we need to accelerate discovery at a rate that will save us from the worst effects of climate change,” said Jennifer Chayes, EECS prof., associate provost for CDSS and dean of the School of Information. “BIDMaP will bring together the founder of an important new field in chemistry and the best artificial intelligence and machine learning group in the world to imagine and create a better future.”

CS Prof. Vern Paxson has won the USENIX Security Test of Time Award. Originally published in 1998, Prof. Paxson’s paper, “Bro: A System for Detecting Network Intruders in Real-Time,” was selected for its lasting impact on the research community and by traditional publication metrics; as of this writing, “Bro” has been cited 3852 times according to Google Scholar. “The paper belongs in the compendium of ‘must read’ classic papers for any graduate security course,” according to the award committee. The award will be presented at the 31st USENIX Security Symposium, which takes place in Boston, MA this year.
