Diamond dust enables low-cost, high-efficiency magnetic field detection

Researchers including EE Prof. Sayeef Salahuddin and postdoc Dominic Labanowski (Ph.D. '17) have created a device that dramatically reduces the energy needed to power magnetic field detectors, which could revolutionize how we measure the magnetic fields that flow through our electronics, our bodies, and our planet.   The researchers found a new way to excite the tiny nitrogen-infused diamond nonocrystals in their magnetic sensor with microwaves, using 1,000 times less power than is required by traditional sensors.  “Our sensors could replace those more-difficult-to-use sensors in a lot of applications from navigation to medical imaging to natural resource exploration,” said Labanowski.

Leslie Field joins panel for Global Climate Action Summit

EE alumna Leslie Field (M.S./Ph.D. '1991), the first woman to earn a Ph.D. from the Berkeley Sensor and Actuator Center (BSAC), will be participating in a panel on "Restoring the Climate: Achievable Solutions" at the 2018 Global Climate Action Summit.  Field is the founder and CEO of Ice911, an organization devoted to mitigating climate change by using reflective sand as a natural heat shield to restore ice in the Arctic.  The panel will "explore the mission of climate restoration and some of the solutions that can get us there, creating jobs and economic benefit in the process."  The Global Climate Action Summit will run from September 12-14 in San Francisco.

Constance Chang-Hasnain wins prestigious Okawa Prize

Alumna and EE Prof. Constance Chang-Hasnain (M.S. '84/Ph.D. '87) has won the 2018 Okawa Prize "for pioneering and outstanding research of VCSEL photonics through the development of their novel functions for optical communications and optical sensing."  The Okawa Prize recognizes "persons who have made outstanding contributions to research, technological development and business in the information and telecommunications fields, internationally."  Chang-Hasnain is Associate Dean for Strategic Alliances in the College of Engineering, Co-director of theTsinghua-UC Berkeley Shenzhen Institute, and the Chair of the Nanoscale Science and Engineering Graduate Group.  Her research interests range from semiconductor optoelectronic devices to materials and physics, with current foci on nano-photonic materials and devices for chip-scale integrated optics.

Key role of micron-scale strain distributions in magnetoelectric multiferroic devices revealed

A research study led by EE Prof. and Associate Chair Jeffrey Bokor and post-doctoral research associate Roberto Lo Conte, among others, on the influence of nonuniform micron-scale strain distributions on electrical reorientation of magnetic microstructures has been highlighted on the news site Advances in Engineering.  The work, which was conducted in the Center for Translational Applications of Nanoscale Multiferroic Systems (TANMS), is the first to thoroughly characterize the micron-scale strain and magnetic response, as a function of an applied electric field, in a composite multiferroic system. Their goal was to come up with a comprehensive behavior and understanding of these materials using direct imaging of both the electrically induced magnetic behavior and the piezo-strain.  These materials systems are of broad technological interest, since they offer a path toward the development of ultralow power magnetoelectric devices which can be useful for manipulation of micro and nano-scale objects such as biological cells. Their work is published in the research journal, Nano Letters.

Gary May claims another rare engineering distinction

EECS alumnus Gary May (M.S. '88/Ph.D. '91, advisor: Costas Spanos), currently serving as the Chancellor of UC Davis, is one of the subjects of a Philadelphia Tribune article titled "ACROSS AMERICA: Three African-Americans Claim Rare Engineering Accomplishment."   May, along with two other African-Americans, was inducted into the National Academy of Engineering (NAE) class of 2018.  NAE membership counts among the highest professional distinctions in engineering.  May was inducted "for contributions to semiconductor manufacturing research and for innovations in educational programs for underrepresented groups in engineering." “We need more diversity in engineering so that we solve problems that take into account all experiences and perspectives," he said. "I encourage young people who are interested in engineering to seek mentors who can help them get on a path that works for them."

Alisha Menon will study ways to help the brain talk to computers

Incoming graduate student Alisha Menon is featured in a community post on the Beaverton Patch titled "Brilliant Teen Seeks PhD At UC Berkeley With STEM Award."  Menon graduated from Oregon Connections Academy (ORCA), a statewide online public high school, at age 16 and took only 3 years to complete her B.S. in Electrical Engineering from Arizona State University.  She will attend Berkeley in the fall on an NSF Graduate Research Fellowship, studying Control, Intelligent Systems, and Robotics (CIR).  "I see the potential for infinite applications - from prosthetics controlled directly by neural signals to brain-computer interfaces that will eliminate the need for secondary interaction tools like keyboards," Menon said. "There are so many directions (that) technology that interacts with the brain can go. Some of these ideas are currently being developed such as virtual reality/artificial reality interfaces, rehabilitation systems, and deep brain stimulation for Parkinson's. Other ideas are more futuristic such as 'typing' using neural signals. I can't wait to be a part of this field as it grows and develops!"

Some EECS contributions to the history of Berkeley's scientific endeavors

Some of the achievements of members of the EECS department are highlighted in a Daily Cal article titled "From cyclotrons to wetsuits: A brief history of UC Berkeley’s scientific endeavors. The article covers  Unix, which was developed by EE alumnus Kenneth Thompson (B.S.‘65/M.S.‘66) in 1969, and RISC, a project directed by CS Prof. Emeritus David Patterson in 1981.  Prof. Randy Katz, who is currently Berkeley's Vice Chancellor for Research, says “The magic of Berkeley is that we are (a) public institution. Our research agenda is about how the work we do impacts society.”

Hanzhong (Ayden) Ye builds VR sharing platform

CS alumnus Hanzhong (Ayden) Ye (M.S. '12, advisor: Björn Hartmann) is profiled in an ejinsight article titled "Former Silicon Valley executives build VR version of YouTube."  In 2016, Ye gave up his lucrative job with Sierra Ventures in Silicon Valley to establish VeeR VR, a Virtual Reality content sharing platform in China.  The platform allows the growing number of content-creating VR enthusiasts to share their work with viewers via the web and mobile devices. In less than two years, the company has grown to 70 employees, while the number of its registered users around the globe has reached more than 20 million.  Customers include corporate users such as travel companies, news agencies, restaurants, and hotels.

Stuart Russell shares his favorite algorithms

CS Prof. Stuart Russell is one of four top experts asked by The Next Web (TNW) "which algorithms they think made the biggest contribution to artificial intelligence and science in general?"  Russell chose Lookahead and Backchaining, which he described as "fundamental modes of decision making.”  Other experts chose Gradient Descent, Convolutional Networks, and Forward-backward.

Blockchain’s Energy Web Foundation names Hervé Touati as first CEO

CS alumnus Hervé Touati (Ph.D. '90, advisor: Robert Brayton) has been named the first CEO of the Energy Web Foundation (EWF), a global nonprofit focused on "unleashing blockchain’s potential to accelerate the transition to a decentralized, democratized, decarbonized, and resilient energy system."  EWF, the world's largest energy blockchain consortium (with a  network of more than 70 affiliates), is building the shared, digital infrastructure—an open-source, scalable blockchain platform—specifically designed for the energy sector’s regulatory, operational, and market needs.  Touati, who comes to the EWF from Shell, is an energy industry veteran with more than two decades of executive-level experience.
