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

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 Real-life Lesson in Design

10/02/08 — What started as a six-week project for freshmen engineering students may create culturally sensitive and energy-efficient housing for a small California Indian tribe. A roundhouse-style design conceived in last spring's E10 Engineering Design and Analysis course has been embraced by members of the Pinoleville Pomo Nation. The tribe plans to submit the UC Berkeley concept when it applies for federal funding to build up to 25 new homes in the Mendocino County community of Ukiah.

A Sky-High Career

09/02/08 — Rex Walheim (B.S'84 ME) has a view that's literally out of this world. He's gazed at Earth from 220 miles in space. A NASA astronaut who grew up in San Carlos, California, the 45-year-old Walheim is a veteran of two shuttle missions to the International Space Station and five spacewalks. His most recent voyage, aboard the shuttle Atlantis, carried him to the space station for 12 days in February. The mission's lead space walker, Walheim helped deliver and install a $2 billion European science laboratory known as Columbus.

King of Cool

08/02/08 — As a student, Chandrakant Patel (B.S.'83 ME) rode the bus every day from the low-income Graystone Hotel in San Francisco's Tenderloin, where he lived, to the verdant UC Berkeley campus, where he studied. Today, a lot has changed for Patel, now a fellow at HP Laboratories in Palo Alto, leading the charge to develop a new generation of energy-efficient data centers.

Hard-Hitting Research

02/02/08 — For 10 years, mechanical engineering professor Dennis Lieu moonlighted as an instructor in the martial art of taekwondo. Concerned about safety, he began testing commercial martial arts headgear that had become standard and required for competitions. His results were startling: many of the helmets failed his tests and would not prevent injuries. His continued research has produced the first technical standard for martial arts protective headgear.
