150W: Bin Yu's "most successful failure"

EECS Prof. Bin Yu is the subject of a 150W profile by the Department of Statistics, where she holds a joint appointment. Yu found refuge from the tumult of Mao Tse Tung's Cultural Revolution in the orderly tables of a math textbook.  Although she placed first in the math section of the graduate school entrance exam, she failed to be accepted as a pupil by the professor she hoped to work with at Peking University because she was a woman.  As a result of this difficult rejection, she switched to studying probability and statistics, where a new world of new opportunities opened to her.  The profile covers Bin Yu's journey from her childhood in China to her days as a graduate student at UC Berkeley,  a career in both academia and industry on the east coast, her return to Berkeley as a professor, and her important contributions to the field of data science.  150W is the year-long celebration of 150 years of women at UC Berkeley.

Natacha Crooks wins 2020 ACM SIGOPS Dennis M. Ritchie dissertation award

CS Assistant Prof. Natacha Crooks has won the 2020 ACM Special Interest Group on Operating Systems (SIGOPS) Dennis M. Ritchie dissertation award for her thesis titled "A Client-Centric Approach to Transactional Datastores."  The award, which recognizes creative research in software systems, was bestowed upon a dissertation which a colleague described as "a landmark, with deep and beautiful results in transactions and distributed consistency, and systems that exploit them."  The award committee commented that "Natacha Crooks’ thesis achieves something rare: a new conceptual framework for client-centric consistency and two efficient systems built on those insights. The document for this attractive package is accessible (in part) to undergraduates and the advanced material is very clearly written. With the enduring popularity of consistency as a research topic in distributed systems for the past several decades it is surprising that a breakthrough as large as Natacha’s took as long as it did."  The work was done at the University of Texas, Austin, advised by Lorenzo Alvisi and Simon Peter.

Progress update: E3S 2019 Transfer-to Excellence program

The Center for Energy Efficient Electronics Science (E3S) Transfer-to-Excellence (TTE) research program is a competitive merit-based program that offers California community college students research opportunities at Berkeley in an effort to encourage them to transfer to a university to purse a Bachelor's degree in science and engineering.  A review of the current activities of the 2019 TTE cohort, whose members received ongoing mentorship over the past year through the TTE online mentoring program, shows that all of the interns are enrolled in science or engineering academic programs and working towards a Bachelor’s degree.  Among them:

Jared Brown (TTE project advisor: EECS Prof. Sayeef Salahuddin), who transferred from Los Angeles Pierce College to UCLA to study mechanical engineering, and is active in the UCLA Samueli Center for Excellence in Engineering and Diversity; Jose Camacho (advisor: EECS Prof. Ming Wu), who transferred from Los Angeles Trade Technical College to  UC San Diego to study Electrical Engineering; Saifuddin Mohammed (advisor: EECS Chair Jeff Bokor), who transferred from Foothill College to UC Berkeley to study EECS after having received the award for best engineering poster presentation at the 2019 SACNAS Diversity in STEM conference, and completing a research internship at LBNL;  current EECS undergrad Harutyun Rehanyan (advisor: ME Prof. Shawn Shadden), who transferred to Berkeley from Los Angeles Valley College after completing a research internship at Cal State Northridge, a software engineering internship with NASA JPL, and summer research at CMU’s Institute for Software Research; and current EECS undergrad Dao Dai (David) Tran (advisor: ME Prof. Shawn Shadden), who transferred from Orange Coast College to Berkeley after completing a software engineering internship at NASA JPL and a research internship at the University of Maryland in machine learning and artificial intelligence.

New "spin-orbit torque" switching technique breaks magnetic memory speed record

EECS Chair Jeffrey Bokor is among an international team of researchers who have published a paper in the journal Nature Electronics that describes a new technique for magnetization switching — the process used to “write” information into magnetic memory — that is nearly 100 times faster than state-of-the-art spintronic devices. The advance could lead to the development of ultrafast magnetic memory for computer chips that would retain data even when there is no power.  In "Spin–orbit torque switching of a ferromagnet with picosecond electrical pulses," researchers report using extremely short, 6-picosecond electrical pulses to switch the magnetization of a thin film in a magnetic device with great energy efficiency. A picosecond is one-trillionth of a second.  The project began at UC Berkeley when Jon Gorchon, now a researcher at the French National Centre for Scientific Research (CNRS) working at the University of Lorraine L’Institut Jean Lamour in France, and Richard Wilson, now assistant professor of both mechanical engineering and materials science & engineering at UC Riverside, were postdoctoral researchers in Bokor’s lab.

"Extreme MRI" chosen as ISMRM Reproducible Research pick

"Extreme MRI: Large‐scale volumetric dynamic imaging from continuous non‐gated acquisitions,” a paper by EECS alumnus Frank Ong (B.S. '13, Ph.D. '18) and his advisor, Prof. Miki Lustig, has been chosen as October's Reproducible Research pick by the International Society for Magnetic Resonance in Medicine (ISMRM).  The paper, in which the researchers attempt to reconstruct a large-scale dynamic image dataset while pushing reconstruction resolution to the limit, was chosen "because, in addition to sharing their code, the authors also shared a demo of their work in a Google Colab notebook."  Lustig and Ong, now a research engineer at Stanford, participated in a Q&A in which they discussed how they became interested in MRI, what makes Extreme MRI "extreme," the culture and value of open science, and why Lustig's grad school paper on compressed sensing became the most cited paper in MRM.  ISMRM is an international nonprofit association that promotes research development in the field of magnetic resonance in medicine to help facilitate continuing education in the field.

Mike Stonebraker wins 2020 C&C Prize

EECS Prof. Emeritus Michael Stonebraker has won the prestigious NEC Computers and Communications (C&C) Prize "For Pioneering Contributions to Relational Database Systems." The prize is awarded "to distinguished persons in recognition of outstanding contributions to research and development and/or pioneering work in the fields of semiconductors, computers, and/or telecommunications and in their integrated technologies."  In the early 1970's, Stonebraker and Prof. Eugene Wong began researching Relational Database Management Systems (RDBMS), which culminated in the creation of the Interactive Graphics and Retrieval System (INGRES), a practical and efficient implementation of the relational model running on Unix-based DEC machines.  It included a number of key ideas still widely used today, including B-trees, primary-copy replication, the query rewrite approach to views and integrity constraints, and the idea of rules/triggers for integrity checking in an RDBMS.  Stonebraker, Wong, and Prof. Larry Rowe, founded a startup called Relational Technology, Inc. (renamed Ingres Corporation), which they sold to Computer Associates in the early 1990's for $311M.  Stonebraker's student, Robert Epstein (Ph.D. '80), founded the startup Sybase, which created the code used as a basis for the Microsoft SQL Server.  Stonebraker also created Postgres in the late 1980's, which made it easier for programmers to modify or add to the optimizer, query language, runtime, and indexing frameworks.  It broadened the commercial database market by improving both database programmability and performance, making it possible to push large portions of a number of applications inside the database, including geographic information systems and time series processing.  Stonebraker retired from Berkeley in 2000 to found more companies and become an adjunct professor at MIT.  His achievements have been recognized with an IEEE John von Neumann Medal in 2005, ACM A.M. Turing Award in 2014, and ACM SIGMOD Systems Award in 2015.

Berkeley Turing laureates take stand to protest immigration policies

CS Prof. Emeritus David Patterson has organized 24 fellow winners of the prestigious ACM A.M. Turing Award, including EECS Prof. Shafi Goldwasser and Profs. Emeritus Manuel Blum, Richard Karp, and Michael Stonebraker, to collectively endorse a presidential candidate as a protest against current government policies that restrict Chinese nationals from studying at American universities. The time allotment on Chinese student visas was reduced from five years to one in 2018 in response to National Intelligence that the nature of collaborative academic environments made institutions vulnerable to espionage by giving foreign powers open access to sensitive research and vanguard technologies.  The laureates penned an open letter in which they asserted that these immigration policies threaten the future of computer research in the United States and could do long-term damage to the tech industry, a critical pillar of America’s economy.  A number of large tech companies, including Google and Facebook, have also spoken out against these immigration policies.  “The most brilliant people in the world want to come here and be grad students,” said Patterson during a group interview with the New York Times in which he stated that he was speaking as a private citizen.  “But now they are being discouraged from coming here, and many are going elsewhere.”
