New tech breakthough will allow drones to fly for days

Prof. Eli Yablonovitch is the co-author of a paper published in the Proceedings of the National Academy of Sciences (PNAS) that describes a groundbreaking discovery which has allowed researchers to raise the efficiency of thermophotovoltaics from 23% (where it has stayed for 15 years) to an unprecedented 29%. This ultralight alternative power source could allow drones and other unmanned aerial vehicles to operate continuously for days.  The paper, "Ultraefficient thermophotovoltaic power conversion by band-edge spectral filtering," co-authored by a 10-person research team that includes postdoc Luis Pazos-Outon, details how a highly reflective mirror installed on the back of a photovoltaic cell can reflect low energy infrared photons to reheat the thermal source, providing a second chance for a high-energy photon to be created and generate electricity.

IEEE EDS Celebrated Member

Leon Chua becomes Celebrated Member of EDS

Prof. Emeritus Leon O. Chua has been named a Celebrated Member of the IEEE Electron Devices Society (EDS), an honor which recognizes "Fundamental Contributions to the Field of Electron Devices for the Benefit of Humanity."  An IEEE Fellow since 1974, Chua is just the 9th person to join this elite group, which includes Nobel Laureates George Smith and Herb Kroemer. Chua is widely known for his invention of the Memristor and the Chua’s Circuit. The award will be presented at the 2019 IEEE International Electron Devices Meeting (IEDM) in December.

Alberto Sangiovanni-Vincentelli and Scott Shenker named Distinguished Fellows of the International Engineering and Technology Institute

Professors Alberto Sangiovanni-Vincentelli and Scott Shenker have been named Distinguished Fellows of the International Engineering and Technology Institute (IETI) for 2019.  They are among 15 professors elected this year, joining well-known experts from all over the world, including Nobel Prize and Turing Award Laureates. Founded in 2015, IETI is a non-profit organization that promotes the innovations of Science, Engineering and Technology across the world. 

2019 VLDB Early Career Award

Aditya Parameswaran wins VLDB Early Career Award

Prof. Aditya Parameswaran wins the Very Large Data Bases (VLDB) Early Career Award, which recognizes a researcher who has demonstrated research impact through a specific technical contribution of high significance since completing the Ph.D. The VLDB Endowment is a non-profit organization incorporated in the United States for the sole purpose of promoting and exchanging scholarly work in databases and related fields throughout the world. Prof. Parameswaran is cited "for developing tools for large-scale data exploration, targeting non-programmers.” 

2019 EECS PECASE Winners

Anca Dragan and Alvin Cheung win Presidential Early Career awards for Scientists and Engineers (PECASE)

Profs. Anca Dragan and Alvin Cheung have been awarded the Presidential Early Career Award for Scientists and Engineers (PECASE), which is the highest honor bestowed by the U.S. government to scientists and engineers in the early stages of their careers. Established in 1996, the PECASE acknowledges the contributions scientists and engineers have made to the advancement of science, technology, education, and mathematics (STEM) education and to community service as demonstrated through scientific leadership, public education, and community outreach. Prof. Dragan was nominated by the National Science Foundation and Prof. Cheung was nominated by the U.S. Department of Energy.

Michael Jordan on the goals and remedies for AI

CS Prof. Michael Jordan has written a commentary in the Harvard Data Science Review (HDSR) titled "Dr. AI or: How I Learned to Stop Worrying and Love Economics" (a play on the title of the film Dr. Strangelove).  In it, he  argues that instead of trying to put "‘thought’ into the computer, and expecting that ‘thinking computers’ will be able to solve our problems and make our lives better," he explores the prospect of bringing microeconomics "into the blend of computer science and statistics that is currently being called ‘AI.'"

New RIOS Lab to expand RISC open-source ecosystem

CS Prof. Emeritus David Patterson, his former graduate student Zhangxi Tan (PhD '13), and Lin Zhang of the Tsinghua-UC Berkeley Shenzhen Institute (TBSI), have been chosen to co-direct the new RISC-V International Open Source (RIOS) Laboratory, an non-profit research lab launched by the TBSI.  RIOS aims to expand and elevate the capabilities of Reduced Instruction Set Computer (RISC) microprocessors.  Patterson, who is currently a distinguished engineer at Google, coined the term RISC in the early 1980s to describe a computer architecture that allowed microprocessors to operate far more efficiently with simple, general instructions.  Nearly all of the 16 billion microprocessors produced annually are RISC processors.

Shruti Agarwal and Hany Farid use facial quirks to unmask ‘deepfakes’

CS graduate student Shruti Agarwal and her thesis advisor Prof. Hany Farid have created a new weapon in the war against "deepfakes," the hyper-realistic AI-generated videos of people appearing to say and do things they never actually said or did.  The new forensic technique, which uses the subtle characteristics of how a person speaks to recognize whether a new video of that individual is real, was presented this week at the Computer Vision and Pattern Recognition conference in Long Beach.  “The basic idea is we can build these soft biometric models of various world leaders, such as 2020 presidential candidates," said Farid, "and then as the videos start to break, for example, we can analyze them and try to determine if we think they are real or not.”

Alexei Efros helps build tool to detect facial manipulation in Adobe PhotoShop

CS Prof. Alexei "Alyosha" Efros has teamed up with student researcher Sheng-Yu Wang and postdoc Andrew Owens, as well as Adobe researchers Richard Zhang and Oliver Wang, to develop a method for detecting and reversing edits to images made using Adobe Photoshop’s Face Aware Liquify feature--a popular tool for adjusting facial features, including making adjustments to facial expressions.  While still in its early stages, this collaboration to train a convolutional neural network (CNN) is part of a broader effort across Adobe to better detect image, video, audio and document manipulations, as well as a step toward democratizing image forensics.

Michael Lieberman wins 2020 IEEE Marie Sklodowska-Curie Award

EE Prof. Michael Lieberman has won the 2020 IEEE Marie Sklodowska-Curie Award for outstanding contributions to the field of nuclear and plasma sciences and engineering.  This IEEE-level Technical Field Award is the highest honor administered by the Nuclear and Plasma Sciences Society.  Lieberman was cited “For groundbreaking research and sustained intellectual leadership in the physics of low-temperature plasmas and their application.”  Prof. Ned Birdsall (1925-2012) won the inaugural award in 2011, making Berkeley EECS the only institution to have won two of these awards.
