Innovation as an engine for peace

03/03/10 — Be it the economy, climate change or health care reform, what are we not worried about these days? There are so many weighty priorities on our minds and, in fact, the College of Engineering is working to address many of these. But I hope this issue of Innovations helps you step back to see an even bigger picture.

Science in the Amazon

03/03/10 — The boys from the Amazonian orphanage decided to name themselves Los Científicos. The Scientists. It was a small but monumental achievement for Rick Henrikson and Richard Novak, two Berkeley bioengineering graduate students. The pair cofounded Future Scientist, a tiny but highly motivated aid organization whose mission is to teach science and practical technical skills to young people in rural, developing regions. Last August, Novak, Henrikson and nine other Future Scientists traveled to Peru for their first pilot project: teaching a two-week crash course on pathogenic microorganisms, disease transmission, optics and solar-powered electricity to schoolchildren living along the Amazon River. This slideshow tells their story.

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.

Oh! The Beauty and Joy of Computing

12/15/09 — "Fun. Easy to learn. Can relate to it." That's what students were saying about a new introductory computing course at Berkeley, established by Dan Garcia, Brian Harvey, Colleen Lewis (B.S.'05 EECS) and George Wang, that will alter the way young people perceive the field. Called "The Beauty and Joy of Computing," the two-unit freshman/sophomore seminar teaches non-majors basic programming skills while exploring big picture topics such as abstraction, world-changing applications and the social implications of computing.

Boy Meets Twirl, a Bollywood Romance

11/13/09 — Bollywood is in the building! Bioengineering undergraduates Nickesh Viswanathan and Anwesh Thakur are two of the male dancers in red who shook up NBC-TV's America's Got Talent this summer with their showstopping routine to “Jai Ho” from Slumdog Millionaire. Their group, Ishaara, was the first Bollywood dance group to advance in the show's history, making it all the way to the quarterfinals before they were eliminated.

Think Globally, Act Locally

10/08/09 — Today's college campuses are seeing a level of student activism not seen since the 1960s. What form does this activism take among engineering students? Here at Berkeley Engineering, you will find hosts of students committed to delivering new solutions to real-world problems.

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.

Heavyweight Champs

09/04/09 — In the world of quirky contests, the U.S. National Concrete Canoe Competition isn't as far-out as, say, the Extreme Ironing World Championships or as appalling as the World Bog Snorkeling Championships, but it has its own ability to astound the public and lure fanatical participants. As devoted undertakings go, it is a little silly and a lot serious, especially here at Berkeley Engineering, where a team of 25 civil engineers won the national championship this summer, their first since 1992.

The Many Faces of Engineering

08/03/09 — What do you see when you think engineer? Our non-engineering colleagues might envision a middle-aged man at a construction site, sporting a hardhat and poring over a set of plans. But we know that engineering has exploded in recent years due to globalization, the IT and biotech booms, clean energy and a host of other factors. As Lawrence Fisher reports in our spring Forefront ("Engineering evolved"), the field today is so broadly multidisciplinary that new applications require the talents of everyone from "software savants and materials mavens" to "aerospace adepts."

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.

A Thrill Ride

01/01/09 — Tim Jacobi adores hurtling through the air, whipping around hairpin turns and feeling his stomach do loops. The Berkeley Engineering master's candidate in mechanical engineering is a roller coaster junkie. "It's such a rush, basically," explains Jacobi, who traces his passion to his early teens. These days, Jacobi is experiencing a new thrill: He designs amusement park rides. His latest assignment involves devising the launch system for what is expected to be the world's fastest pneumatically launched roller coaster.

A Better Energy Grid for the Developing World

11/02/08 — According to the UN, lack of access to electricity and fuel in rural areas contributes to 1.6 million deaths per year and perpetuates poverty. For engineers and energy suppliers working in this environment, bringing power to these populations requires a multi-pronged effort, not just to build the grids themselves, but also to plug into the human factors of operating within a particular culture and under what is usually a cash-strapped government. Christian Casillas, a Ph.D. student advised by Professor Daniel Kammen in the Energy and Resources Group, is balancing these two sides of the problem, working out the details of a roadmap to bring reliable electricity to the fishing villages along Nicaragua's eastern coast.

A (Golden) Bear of a Bridge

08/02/08 — It's the size of a theater catwalk and weighs just 142 pounds. But the gently arched bridge -- designed, built and ambitiously named "Calatrava" by Cal engineering students -- is the new heavyweight champ of collegiate bridge building. The 21-foot-long span swept a field of 42 finalists on May 23-24 to capture top honors at the 2008 National Student Steel Bridge

New Beginnings

06/02/08 — On May 24, I participated in my first commencement as dean of Berkeley Engineering. It filled me with pride to watch 1,045 excited and rain-soaked graduates walk, dance or otherwise cross the Greek Theatre stage to celebrate their success in completing some of the most difficult majors UC Berkeley has to offer.

Building a Better Mouse

05/02/08 — Computer mice are a weighty matter for BingYune Chen. Chen, a senior who graduates this month in bioengineering, is studying how weight affects the speed, accuracy and ease of use of a computer mouse. “It's a new issue,” says the 22-year-old Chen, who helped conduct a pilot project as an undergraduate researcher at the UCSF–UCB Ergonomics Laboratory, where he is now an employee. While extensive research has been done on the design of computer mice, Chen says, little is known about mouse weight and its impact on performance.

A Doctor in the (Jazz) House

04/02/08 — George Ban-Weiss will soon have a new title to accompany his growing fame in Bay Area jazz circles. The professional bass player is about to become a Ph.D. Having performed at such venues as Yoshi's in Oakland, the Jazz Bakery in Los Angeles, and Smalls in New York City, Ban-Weiss expects to receive his doctorate in mechanical engineering from UC Berkeley in May. The 27-year-old is wrapping up research exploring emissions from gas and diesel vehicles and their respective impact on air quality.

Play It Again, IRENE

01/02/08 — EECS undergraduate Henry Wang had never heard of Enrico Caruso until last year. That's a surprising admission given that the 21-year-old senior now spends hours weekly scrutinizing the famed tenor's rendition of La Donna è Mobile. Wang is part of an ambitious project that seeks to preserve historic collections of music, speeches and other audio recordings dating back to the earliest days of recorded sound.
