Lensless Cameras May Offer Detailed Imaging of Neural Circuitry

EECS graduate students Nick Antipa and Grace Kuo, along their advisor Associate Prof. Laura Waller, have penned an article for Photonics Media titled "Lensless Cameras May Offer Detailed Imaging of Neural Circuitry" about a new architecture which could enable simultaneous monitoring of millions of neurons in 3D space at frame rates limited only by image sensor read times.  Instead of using a large, lens-based light-field microscope to image individual brain neurons, the DiffuserCam lensless imaging architecture consists of a diffuser placed in front of a 2D image sensor. When an object is placed in front of the diffuser, its volumetric information is encoded into a single 2D measurement.   Borrowing tools from the field of compressed sensing, a 3D image is reconstructed by solving a sparsity-constrained optimization problem.

RAFAR wins Best Student Paper Award at MARSS 2018

"Bidirectional thin-film repulsive-/attractive-force electrostatic actuators for a crawling milli-robot," written by recent EE alumnus Ethan Schaler (Ph.D. '18), his advisor Prof. Ron Fearing, and two undergraduates from other departments (Loren Jiang in BioE and Caitlyn  Lee in E3S), received the Best Student Paper Award  from the International Conference on Manipulation, Automation, and  Robotics at Small Scales (MARSS) 2018 in Nagoya, Japan in July. The authors demonstrated a new thin-film electrostatic actuator (RAFA)  capable of generating bidirectional repulsive- and attractive-forces:  156 Pa in repulsion and 352 Pa in attraction, when operating at up to  1.2 kV. They used this actuator to power RAFAR, a 132 mg milli-robot  that crawls at 0.32 mm/s with anisotropic friction feet.   Schaler will be joining NASA Jet Propulsion Laboratory (JPL) this summer.

Katherine Yelick to testify before House Committee on Science, Space and Technology

Prof. Katherine Yelick is one of four witnesses set to testify before the U.S. House of Representatives’ Committee on Science, Space and Technology.  The committee is conducting a hearing on “Big Data Challenges and Advanced Computing Solutions.”  Yelick, who is the Associate Laboratory Director for Computing Sciences at Berkeley Lab, will discuss the emerging role of machine-learning methods that have revolutionized the field of artificial intelligence and may similarly impact scientific discovery.  The hearing will be livestreamed on Thursday, July 12, 2018.

Oasis Labs raises $45M for ‘privacy-first’ cloud

Oasis Labs Inc., a startup co-founded and led by Prof. Dawn Song to build a high-performance cloud computing platform on blockchain, announced that it has raised $45 million in funding. Oasis is building a cloud-based blockchain platform intended to outdo existing distributed-ledger implementations in two key areas: performance and privacy. Song elaborated in a statement that “the Oasis platform aims to give users control over their data, without the underperformance and lack of privacy of existing blockchain platforms.”  The funding round saw the participation of more than 70 investors including Accel and a16z crypto, an Andreesson Horowitz fund.

Stuart Russell dissects the hype around AI in Paris

CS Prof. Stuart Russell's speech at an event at the American Library in Paris titled "AI And The Future Of Humanity" has been described as a "potential game-changer."  The lecture is explored in an article for Forbes by  Lauren deLisa Coleman titled "Here's The Real Reason You're Terrified Of The $1.2-Trillion AI Industry But Don't Yet Truly Know Why."  Russell is credited with dissecting the hype around AI, including affirming the value of the technology to humanity while asking questions about the ways it might evolve, and exploring some of the shared strategies that are needed during the foundation of this evolution.  The event was produced by Ivy Plus European Leaders, a think tank of alumni from leading US and European Universities, in partnership with UC Berkeley and UC Davis.

Alessandro Chiesa named one of MIT TR's 35 Innovators Under 35

CS Assistant Prof. Alessandro Chiesa has been named to the 2018 roster of MIT Technology Review's "35 Innovators Under 35."  The list acknowledges "exceptionally talented young innovators whose work we believe has the greatest potential to transform the world."  Chiesa, who co-founded Zcash, was cited in the Pioneers category for "a cryptocurrency that’s as private as cash."  Zcash employs a cryptographic protocol called a succinct zero-knowledge proof--an efficient way to convince both parties to a transaction that something is true without divulging any other information. It allows people to do transactions online without risking their privacy or exposing themselves to identity theft.  Launched 4 years ago, Zcash now has a market cap of over a billion dollars.

Joseph Hellerstein uses machine learning to search science data

Prof. Joseph Hellerstein is one of the principal investigators of a research team who are developing innovative machine learning tools to pull contextual information from scientific datasets and automatically generate metadata tags for each file. Scientists can then search these files via a web-based search engine for scientific data, called Science Search, that the Berkeley team is building.  The work is being done in conjunction with the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) including principal investigators Katie Antypas, Lavanya Ramakrishnan and Gunther Weber.  “Our ultimate vision is to build the foundation that will eventually support a ‘Google’ for scientific data, where researchers can even search distributed datasets," said Ramakrishnan. "Our current work provides the foundation needed to get to that ambitious vision.”

Tsu-Jae King Liu named Dean of Berkeley Engineering

Prof. Tsu-Jae King Liu has been selected as the new Dean of the College of Engineering.  King Liu served as Associate Dean for Research in the College from 2008-12, Chair of the EECS department from 2014-16, and Vice Provost for Academic and Space Planning on the Berkeley campus from 2016-18. She is a member of both the National Academy of Engineering and the National Academy of Inventors, and is internationally recognized for her research innovations in semiconductor devices and technology, garnering numerous awards and honors for her work.  King Liu is replacing Prof. Shankar Sastry, who held the post for more than 10 years.

Bin Yu wins COPSS 2018 Elizabeth L. Scott Award

EE/CS Prof. and alumna Bin Yu (M.S. '87/Ph.D. '90) has won the Committee of Presidents of Statistical Societies (COPSS) 2018 Elizabeth L. Scott Award.  This award is granted to an individual who has helped foster opportunities in statistics for women, exemplifying the spirit of mathematician and statistician Elizabeth L. Scott. Scott, who like Yu was a Cal alumna and professor, was a founding member of Berkeley's statistics department and fought hard for women's equal treatment on campus and beyond.  COPSS is comprised of the presidents, past presidents and presidents-elect of five Northern American statistical societies, and their awards are considered among the most prestigious in the field of statistics. Yu, who has a split appointment in EECS and Statistics, is interested in statistical inference, machine learning, and information theory. Her collaborations are highly interdisciplinary and include scientists from genomics, neuroscience, precision medicine, and political science.

Joseph Gonzalez wins 2018 Okawa Research Grant

CS Assistant Prof. Joey Gonzalez has won a 2018 Okawa Research Foundation Grant.  Okawa Research Grants are bestowed for "studies and analyses in the fields of information and telecommunications."  Gonzalez's research interests are at the intersection of machine learning and data systems. The award will be presented in San Francisco in the fall.
