Robert J. Wood's RoboBee X-Wing flies solo

An untethered bee robot co-created by EE alumnus Robert J. Wood (PhD '04, advisor: Ron Fearing) graces the cover the of the June 2019 issue of Nature magazine and is the subject of a Wired article titled "What Could Possibly Be Cooler Than RoboBee? RoboBee X-Wing."  Wood, now a professor of engineering and applied sciences at Harvard, is one of the creators of the RoboBee X-Wing, an aerial vehicle the size of an insect that is capable of untethered flight.  It has four wings driven by two piezoelectric actuators and carries a 60-mg photovoltaic array and a 91-mg signal generator, giving it a thrust efficiency matching that of similarly sized insects.

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.

Raluca Ada Popa Named an MIT Technology Review 2019 Innovator Under 35

Today, the MIT Technology Review announced Raluca Ada Popa has been named to MIT Technology Review’s prestigious annual list of Innovators Under 35 as a Visionary. Every year, the world-renowned media company has recognized a list of exceptionally talented technologists whose work has great potential to transform the world.

Prof. Popa is a co-founder of the RISELab where she is developing a learning and analytics framework that can run on encrypted data.

Gideon Lichfield, editor-in-chief of MIT Technology Review, said: “MIT Technology Review’s annual Innovators Under 35 list is a chance for us to honor the outstanding people behind the breakthrough technologies of the year that have the potential to disrupt our lives. These profiles offer a glimpse into what the face of technology looks like today as well as in the future.”

Joseph Gonzalez: at the intersection of machine learning and data systems

EECS Assistant Prof. Joseph Gonzalez is the focus of a profile for the Association for Computing Machinery's "People of ACM" series.  Gonzalez, who works at the intersection of machine learning and data systems, desribes how and why his field has grown over time, where it might be heading, and what challenges might need to be addressed in the future.  "Today progress is largely limited by creativity and our budget for compute resources and data," he says. "Machine learning frameworks...provide the necessary abstractions to hide the complexity of differentiation, optimization, and parallel computation, freeing the modern data scientist to focus on the learning problem. These frameworks build on advances in data systems and scientific computing to unlock new parallel hardware."

Elizaveta Tremsina is 2019 ACM SRC Grand Finals Winner

A paper written by recent graduate Elizaveta Tremsina (B.S. '19 CS/Physics/Applied Math) has taken third place in the undergraduate category of the 2019 ACM Student Research Competition (SRC) Grand Finals.  The paper, titled "Your Story Recorded in a Magnet: Micromagnetic Simulations of Spin-Orbit Torque in Multi-layer Structures," was a continuation of the first place poster she presented at the 2018 Richard Tapia Celebration of Diversity in Computing.    "I am extremely thankful to the Berkeley EECS department for the amazing 4.5 years and for the unique chance to participate in cutting-edge research with Dr. Salahuddin's group and also attend the Tapia conference (my first one back in 2016 and last year)," she said. "I hope that more Berkeley undergrads participate in this competition in the future, be it at Tapia or other ACM conferences."  Tremsina was presented with her award at the ACM awards banquet last weekend.

Nadia Heninger wins Borg Early Career Award

EECS alumna Nadia Heninger (B.S. '04) has won the 2019 Borg Early Career Award (BECA).  The BECA  is given to a woman in computer science and/or engineering who has made significant research contributions and who has contributed to her profession, especially in the outreach to women.  After graduation, Heninger earned a Ph.D. from Princeton and is currently an associate professor in Computer Science and Engineering at UC San Diego.  She is known for her work on freezing powered-down security devices to slow their fading memories and allow their secrets to be recovered via a cold boot attack, for her discovery that weak keys for the RSA cryptosystem are in widespread use by internet routers and other embedded devices, and for her research on how failures of forward secrecy in bad implementations of the Diffie–Hellman key exchange may have allowed the NSA to decrypt large amounts of internet traffic via the Logjam vulnerability.

Berkeley paper wins 2018 IEEE EDS George E. Smith Award

"Improved Subthreshold Swing and Short Channel Effect in FDSOI n-Channel Negative Capacitance Field Effect Transistors," has won the 2018 IEEE Electron Devices Society (EDS) George E. Smith Award.  The paper was co-authored by current postdoc Korok Chatterjee, graduate student Ava J. Tan, former postdocs Daewoong Kwon,  Angada B. Sachid, Ajay K. Yadav and Hong Zhou, EE Profs. Chenming Hu and Sayeef Salahuddin, and LBNL's Roberto dos Reis. The award recognizes the best paper appearing in a fast turn around archival publication of the IEEE Electron Devices Society, targeted to IEEE Electron Device Letters.
