Dan Klein and Angjoo Kanazawa win 2022 Bakar Fellows Spark Awards

EECS Prof. Dan Klein and Assistant Prof. Angjoo Kanazawa have won 2022 Bakar Fellows Spark Awards.  These awards are designed to accelerate Berkeley faculty-led research "to tangible, positive societal impact through commercialization."  Bakar Fellows become part of a campus ecosystem that provides support and programs to assist them in introducing discoveries to the market.  Klein is developing a device that will allow users to communicate through computers by "silent speech"--that is, mouthing words without vocalizations. This technology, which may take the form of a headset that can track a user's facial muscles and translate it into sound, would benefit people with special needs as well as make it easier for everyone to hold private phone conversations in public.  Kanazawa plans to build 360 consumer cameras that can capture 4K video at 90 frames per second using an artificial intelligence framework and the latest volumetric neural rendering techniques.

Ruzena Bajcsy and Klara Nahrstedt first mother-daughter pair elected to NAE

EECS Prof. Emerita Ruzena Bajcsy and her daughter, Klara Nahrstedt, are the first mother-daughter pair to be elected to the National Academy of Engineering (NAE).  Bajcsy has been a member of the NAE since 1997 and Nahrstedt, the Chair of the Grainger College of Engineering at the University of Illinois, Urbana-Champaign, was elected in February.  The two sat down for a Fireside Chat at the National Center for Supercomputing Applications last month to discuss the accomplishment.  “I’m a proud mother,” Bajcsy said. “And I’m thrilled to have been in this profession we have both shared.”  Bajcsy is known for her work in human-centered computer control, cognitive science, robotics, image processing, and artificial vision, as well as her cross-disciplinary leadership.  Nahrstedt researches security across shared systems, including multimedia distributed systems, wired and wireless networks, mobile systems, power grids, and edge-cloud systems.  Both women faced daunting challenges during  their careers. “We were ridiculed, and we were doubted. But you have to be strong,” Bajcsy said.  They emphasized that building a strong support network was critical to success.  “I learned that because of my mother,” said Nahrsted, "and through it I quickly believed I could do whatever I put my mind to.”  Following in their footsteps, Bajcsy's granddaughter and Nahrstedt's niece, Andrea Bajcsy, is currently a doctoral candidate at Berkeley EECS, in her final term.  She is slated to start as an Assistant Professor at Carnegie Mellon in Fall 2023.

Kam Lau named 2022 Caltech Distinguished Alumni

EECS Prof. Emeritus Kam Lau has received the 2022 California Institute of Technology (Caltech) Distinguished Alumni Award (DAA).  Caltech's highest honor, the DAA is presented each year "to a small number of alumni in recognition of personal and professional accomplishments that have made a noteworthy impact in a field, on the community, or in society more broadly."  Lau was cited for "his innovations in and commercialization of laser diode and radio-over-fiber technologies that broadly enable today's wireline and wireless high-speed internet access as well as enabling progress in interplanetary exploration, radio astronomy, and particle physics research, and for his remarkable artistic contributions to the Chinese ink painting movement." While still in high school, Lau joined the first wave of the New Ink Painting Movement in Hong Kong, blending traditional Chinese ink and wash painting with a modern sensibility.   He earned three degrees from Caltech: a B.S. and M.S. in 1978,  and a Ph.D. in 1981.  He joined Ortel Corporation as a founding staff member and taught at Columbia University for two years before coming to Berkeley. His development of the ultra-stable radio frequency (RF) over fiber system made ultra-precise, long-distance synchronization of antennas possible, and enabled both ground-based communication networks and spaceborne planetary radar imaging systems.

He was the youngest-ever recipient of a B.A. and Master's in computer science from the University of Illinois Urbana-Champaign, and is the founder of Multifactor.com.  Their fellowships will fund up to five years of graduate research with "the freedom to pursue innovative ideas wherever they may lead."  Hertz Fellows also receive lifelong professional support, including mentoring and networking with a powerful community of more than 1,200 researchers.

BAIR Climate Initiative creates partnerships to fight climate change

Berkeley Artificial Intelligence researchers are joining forces with climate experts, government agencies, and industry, as part of the new Berkeley AI Research (BAIR) Climate Initiative, a multi-disciplinary student-led hub dedicated to fighting climate change.  The effort is being led by co-founding director CS Prof. Trevor Darrel and organized by three of his graduate students, Colorado Reed (co-advised by Kurt Keutzer), who will help lead the initiative, Medhini Narasimhan, and Ritwik Gupta (co-advised by Shankar Sastry).  Their objective is to develop AI techniques that address problems with data processing, particularly involving massive data sets. To maximize the benefit to other researchers studying the same problems around the world, all work done by the initiative will be openly published and available without exclusive or proprietary licensing.  One of their first projects, “The Fate of Snow,” will be a collaboration between BAIR Climate Initiative researchers and other scientists and policy experts on the Berkeley campus, Berkeley Lab (LBNL), Meta AI (which belongs to Meta Platforms, Inc.) and the Center for Western Weather and Water Extremes. The researchers plan to apply AI methods to a multitude of openly available weather and satellite data sources to estimate how much water is in the Sierra Nevada snowpack and forecast what that will mean for streadmflow in the region.
