During three prolific decades in Berkeley's labs and classrooms, the professor of bioengineering and mechanical engineering stacked up nearly 40 patents and cofounded half a dozen startups in surgical techniques, bionic technology and imaging. Now Rubinsky is finding inspiration in his new role as health care advocate for the economically disadvantaged, building endorsement for his conviction that inexpensive but scientifically advanced technologies can improve health care for underserved populations.

In search of an earthquake-proof building

03/02/10 CNN.com — Earthquakes alone don't kill people; collapsed buildings do. But can people engineer buildings that wouldn't crumble when subjected to the rumblings of the Earth? High costs keep countries such as Haiti from adopting the latest building techniques and technologies, said Nicholas Sitar, professor of civil and environmental engineering at UC Berkeley. He said making buildings more basic might actually make them stronger and would cost less than high-tech upgrades

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.

Meet the Next Builder of Berkeley Bioengineering

10/08/09 — After 32 years at other universities, Matthew Tirrell joined Berkeley in July, and from his new Stanley Hall office, he ruminates on the job he's just taken, that of Department of Bioengineering chair. "A chair's creativity is needed when faculty members want help getting their ideas enacted -- that's enabling. And sometimes a chair gets a good idea of his or her own and has a chance to lead. Managing is fine, but I like enabling and leading best. I'd like to help this department define what it could be."

Strongwoman Finds Her Engineering Niche

10/08/09 — Transfer student Romy Fain came to Berkeley Engineering via a route that could have been plotted by Rube Goldberg. Originally a creative arts major at San Francisco State University, Fain ventured out as a touring musician, a bike mechanic, the owner of her own metal fabrication company and even a circus strongwoman before arriving in Berkeley two years ago to pursue her bachelor's degree in mechanical engineering. Now entering her senior year, Fain believes she's landed right where she belongs.

One of BART’s Biggest Fans

09/04/09 — Barney Smits (B.S.'92 ME) rides Bay Area Rapid Transit every weekday from his Oakland home to his office, two blocks from Oakland's 19th St. station. "I take it just about everywhere I can," he says. "To the opera in the city, to the airport when I'm traveling. Once you're used to it, it's the absolute best, easiest way of getting around." But then he might be biased. Smits, 53, is the transit system's principal mechanical engineer, a job he's held for several years. He's one of the guys who makes sure that the 20 miles of tunnel and 208 miles of track and all the stations and system facilities are safe for riders like him, and you.

Revving up the Internal Combustion Engine

03/02/09 — In the quest for smarter cars of the future, Hunter Mack (M.S.'04, Ph.D.'07 ME) is putting a new spin on the internal combustion engine. Mack's focus as a postdoctoral researcher at Berkeley Engineering is an innovative system called HCCI that behaves like a cross between a gas and a diesel engine. HCCI, shorthand for homogeneous charge compression ignition, delivers up to 30 percent better fuel economy than gas engines, emits far fewer emissions than a typical diesel and isn't fussy about what's pumped in its tank. And because HCCI is a modification of a conventional engine, the system as a whole or elements of it could be installed in new cars within 5 to 10 years.

Diabetes Management, Simplified

02/02/09 — Individuals with diabetes live by the numbers. Glucose levels. Insulin dosages. Carbohydrate consumption. Dates. Times. Amounts. By writing each number in a logbook, they help their doctors manage the disease so they can stay healthy. The recordkeeping is onerous; yet, without complete data sets, doctors may miss trends and recommend ineffective treatments. Without tightly controlled day-to-day management, diabetes can lead to serious complications. As a side project to his research in mechanical engineering, recent graduate Chris Hannemann (M.S.'08 ME) began developing a system to help automate the process. His proposal harnesses Web-based applications and popular mobile devices to make it easier to live with the disease.

A Thrill Ride
