A thriller in the midst of EECS

05/05/10 — Picture this: The security of computers worldwide hangs in the balance. Cult-like followers of the Greek philosopher Pythagoras are suspected of a nefarious plot to crack the cryptographic code protecting virtually everyone's digital data. Who ya gonna call? In his debut thriller, Tetraktys, Ari Juels (Ph.D'96 EECS) crafted a stereotype-shattering sleuth to take on the bad guys. His fictional hero: an intrepid young doctoral candidate schooled in the classics and studying computer science at-you guessed it-UC Berkeley's College of Engineering.

Engineering health reform

04/07/10 — The health care reform bill enacted last month is the most far-reaching domestic policy the nation has seen in decades. Only time will tell us all the ramifications of this historic legislation. As the acting dean of the College of Engineering I ask, how can engineers help patients, physicians and providers make the best use of the changes ahead?

Blue and gold make green in Silicon Valley

Want a job? Get a computer science degree

02/22/10 Computerworld — If you want to have a high-paying job on graduation day, study computer science. That's the advice coming out of the top U.S. computer science programs. "We feel that the bust is over, and the number of computer science students is going to keep increasing," says Kate Riley, director of operations for the Electrical Engineering and Computer Sciences Department at UC Berkeley. Undergraduate enrollment in UC Berkeley's EECS degree program is up 8% from last year.

Mechanized marvels

02/03/10 — Their ingenious designs integrate mechanical and electrical systems into working prototypes that may zoom, zing, fly, agitate, pull, dispense or write their way into engineering glory. At the end of every semester, students in ME 102 "Mechatronics" demonstrate their final mechanical engineering design projects for the public during an open house in Etcheverry Hall. "It was almost overwhelming to see what the students could not only dream up but also fabricate and test in such a short amount of time," says graduate student instructor Sarah Wodin-Schwartz.

Could robot cockroaches help Haiti earthquake victims?

01/19/10 FOXNews.com — Tech wizards at UC Berkeley's Department of Electrical Engineering are developing mini-robots to help locate earthquake survivors easily, cheaply, and quickly, without jeopardizing the lives of rescuers. They're made of cardboard, plastic, and parts of computers and bits of old toys, and operated by remote control. The goal of the project: to develop swarms of the cheap, diminutive robots that can hunt down the survivors of disasters and relay the location of survivors back to the surface.

Robots could assist in quake search and rescue

01/18/10 ABC News — Earthquake rescues could be made safer and faster with a new robot being developed at UC Berkeley by engineering grad students Paul Birkmeyer and Kevin Peterson with Professor Ron Fearing.

Dr. Song’s Cure for Sick Computers

12/15/09 — Malware is tough to defeat. Once a piece of malicious software such as a virus or worm attacks, it might take days or weeks before computer security professionals release a fix or other countermeasure, says EECS associate professor Dawn Song (Ph.D.'02 EECS). But Song -- named one of Technology Review's 2009 Young Innovators Under 35 -- has created what she calls a "game-changing" technology in the security landscape, significantly cutting the amount of time it takes security analysts to address a malware problem.

Sustainable Energy Solutions

11/13/09 — Next month, representatives from around the world will convene at the United Nations Climate Change Conference in Copenhagen in hopes of providing the broad outline for a new agreement that will reduce greenhouse gas emissions to sustainable levels. It is critical that, unlike Kyoto, the new agreement simultaneously provide for sustainable growth and energy utilization.

Brain–Machine Interface Holds Promise for Prosthetics

09/04/09 — "Practice makes perfect" is the maxim drummed into anyone struggling to learn a new motor skill, be it riding a bike or developing a killer backhand in tennis. New research by UC Berkeley assistant professor of electrical engineering and computer sciences Jose Carmena and colleagues now reveals that the brain can also achieve this motor memory with a disembodied device. The study provides hope that physically disabled people could one day master control of artificial limbs with greater ease.

Nanoneedles Point the Way to Sharper Sensors

06/04/09 — Last year, Connie Chang-Hasnain and graduate student researcher Linus Chuang were searching for a better lab recipe for growing nanowires, conductive threads so thin that every atom they contain has a significant effect on their overall electrical properties. Following the vapor-liquid-solid (VLS) technique for creating semiconductor crystal nanowires, they deposited successive layers of gallium arsenide onto a silicon wafer substrate. But in one low-temperature batch, an area of the silicon lacked the usual gold nanoparticles from which each crystal grows. Under careful examination of the region, they didn't find what they were expecting. Instead of uniform-diameter threads sticking up, they saw tall, needle-like pyramids with hexagonal bases and sharp points. They had discovered a new nanostructure.

Nano Song Goes Viral

06/04/09 — A music video that playfully celebrates all things nano has become a megahit for three Berkeley Engineering graduate students and their Cal team.

Big Network is Watching You

02/02/09 — With Enhanced GPS, cell phones will soon be able to pinpoint a user's location down to a specific street address. For users, this new capability will improve directions, mapping and other location-based phone services. Meanwhile, marketers plan to use the data to track consumer preferences and personalize recommendations shown onscreen. While improved recommendations are nice, so is personal privacy, and having some company tracking your every move poses risks, no matter what the information is used for. Engineering professor John Canny is developing a privacy-protection scheme called Ant Club Trails that will let companies personalize your recommendations while preventing them from determining your identity.

Mobile Phone Metamorphosis

11/02/08 — Paul Jacobs (B.S. '84, M.S. '86, Ph.D. '89 EECS) sees no limits to what next-generation cell phones will do. As a development engineer, an executive and now CEO of Qualcomm, the San Diego-based wireless technology company, Jacobs has played a major role in the transformation of the mobile phone. Along with their original function in voice communications, the devices have evolved into wireless computers, music players, digital cameras, navigational tools, and medical diagnostic and monitoring equipment. And, says Jacobs, still more advances are on the way. "Innovation comes from being open to diverse ideas," says Jacobs, who holds more than 35 patents for his inventions. "The world changes and you change."

Sensors Could Give Elderly an Assist

10/02/08 — Most people hope to live healthy, independent lives through their elderly years. But that's not always the case because, as people age, they and their loved ones have to worry about not only illnesses, but also injuries, especially from falls. For seniors, falling is the leading cause of injury deaths, nonfatal injuries and hospital admissions. But one team of researchers is working to enable the elderly to live independently through a network of body sensors. The project could allow computers to remotely monitor and analyze the activity of seniors so that, if they fall or stop moving, help can arrive quickly.

Securing Our Cyberspace

09/02/08 — Information technology is pervasive in making our lives so much easier, that is, until we're paralyzed by a virus invading our home computer or crippled by an enterprise-wide system crash. The larger implications are something we don't even want to think about: What would happen to your life as you know it if your personal identity were stolen or, worse, some malicious entity hacked into just one component of our critical infrastructure, like the power grid or the air traffic–control infrastructure?
