One engineer’s effort to tame a dangerous world

09/08/10 — Robert Bea's got a problem. In fact, he's got several: The Deepwater Horizon. Hurricane Katrina. California's fragile 100-year-old levees. These are just three of more than 600 disasters or disasters-in-waiting Bea has investigated in his 57-year career as a flood protection engineer, oil and ocean engineer, risk management specialist, UC Berkeley professor of civil and environmental engineering and one of the nation's foremost authorities on disaster mitigation. Since the explosion of the Deepwater Horizon offshore oil rig, the 73-year-old Texan has been traveling from coast to coast, investigating the site, serving on advisory panels, writing reports, and giving abundant media interviews, hoping to make sure nothing like this accident ever happens again.

H.P. to work with Hynix on new computer memory chips

08/31/10 The New York Times — Hewlett-Packard said Tuesday that it would commercialize a new computer memory technology called memristors with Hynix, the South Korean chip maker. The agreement to build the memory chips validates the work of Leon O. Chua, a UC Berkeley electrical engineering professor. In 1971, he proposed a fourth basic circuit element (the other three are the resistor, capacitor and inductor) and called it a memristor, or memory resistor, as a simpler alternative to transistors that would allow more computer memory to be packed in even smaller devices.

UC Berkeley researchers study health effects of 3D

08/29/10 ABC News — More 3D movies than ever are in theaters now and manufacturers are selling 3D TVs. Yet surprisingly little is known about the effects of stereo vision on our brains. Researchers at Berkeley are applying cutting-edge technology to find out what happens when 3D is not produced correctly. UC Berkeley Visual Science Professor Martin Banks' lab is breaking new ground in studying the way we perceive depth. Enabling test subjects to see two screens at once using mirrors, his team has established some of the things that lead to bad 3D

New Orleans may still be vulnerable to major storm

08/27/10 National Public Radio — Many believe that one of the worst disasters in U.S. history - the flooding of New Orleans - wasn't caused by Hurricane Katrina but by the failure of the flood protection system. Five years later, billions of dollars have been spent to protect the city, but the new flood protection system still leaves New Orleans vulnerable to a major storm. Robert Bea, an engineering professor at UC Berkeley, has spent some 14,000 hours studying New Orleans flood protection since Katrina, and believes that even with the new upgrades, the levees and floodwalls are inadequate, more of a "patchwork quilt" than a true flood protection system.

Can New Orleans’ revamped levee system withstand next storm?

08/26/10 PBS NewsHour — The state of the levee system in New Orleans continues to be a major concern, especially during hurricane season. PBS NewsHour speaks with Bob Bea, civil engineering professor at UC Berkeley, about the current coastal protection system in the city.

$122 million grant to convert sunlight to fuel

07/23/10 San Francisco Chronicle — Scientists from UC Berkeley, Stanford University and the Caltech have been given $122 million to come up with ways to produce fuels directly from sunlight. The U.S. Department of Energy announced the grant Thursday, with the mission to develop practical methods of manufacturing "carbon neutral" fuels similar to the way plants create energy via photosynthesis. "We're not talking about solar panels," said Peidong Yang, a professor of materials science and engineering at UC Berkeley who heads the Bay Area branch of the project. "We are going to develop technology to convert solar energy directly into chemical fuels like methanol, ethanol or just gasoline, through CO2 reduction."

Gulf deep-water drilling should resume on case-by-case basis, expert says

07/22/10 Bloomberg.com — U.S. regulators could end a blanket ban on deep-water oil drilling by increasing oversight of troubled wells and improving safety industrywide, a UC Berkeley engineering professor who studies catastrophes said in an interim report on the sinking of the Deepwater Horizon rig in the Gulf of Mexico. Robert Bea said regulators should determine which drilling operations should be suspended "on a case-by-case basis" as the industry works to improve blowout prevention equipment, inspection procedures and worker training programs.

Energy Secretary emerges to take a commanding role in effort to corral well

07/16/10 The New York Times — Energy Secretary and former director of the Lawrence Berkeley National Laboratory Steven Chu may hold a Nobel Prize in physics, but he has no training in geology, seismology or oil well technology. Nevertheless, he has stepped in repeatedly to take command of the effort to contain BP's runaway well, often ordering company officials to take steps they might not have taken on their own.

07/14/10 National Public Radio — "How To Defeat Your Own Clone And Other Tips For Surviving The Biotech Revolution," by UC Berkeley bioengineering Ph.D. Kyle Kurpinski and bioengineering lecturer Terry D. Johnson, offers up a detailed contingency plan for a future of biotechnological marvel. They've engineered a whirlwind tour that leaves you amused, yet newly fluent in bioengineering and human genetics. Their premise may be fantasy, but the science is real, and the authors' comic book spunk delivers a serious message.

Explaining the equation behind the oil spill disaster

07/03/10 Science News — Catastrophes come in all shapes and sizes, but some basic causative principles underlie most of them. Robert Bea, an engineer at the University of California, Berkeley, has studied system failures from space shuttle explosions to levee breaks during Hurricane Katrina -- but as a former oil rig worker he is most familiar with drilling disasters. Bea has thus assumed a key role in analyzing the response to the Deepwater Horizon spill in the Gulf of Mexico. He spoke with Science News about why the spill could have been foreseen.

Gene therapy shows promise for blocking HIV, controlling AIDS

06/15/10 Bloomberg — Two cutting-edge medical technologies, stem cell transplantation and gene therapy, were combined in an attack on the AIDS virus that may lead to new strategies for treating people infected with HIV. "If you could develop a therapy to make HIV-proof blood cells, then you could create a true cure for HIV. This is a very promising clinical trial that takes us in that direction," said David Schaffer, a professor of bioengineering at UC Berkeley, who co-directs the school's stem cell center and wrote a commentary accompanying the study.

Engineer Robert Bea a student of disaster

06/06/10 San Francisco Chronicle — UC Berkeley engineering professor Robert Bea, 73, a former Shell Oil executive, is a student of disaster. He has spent decades investigating catastrophic engineering failures, from the New Orleans levee breaches in Hurricane Katrina to the space shuttle Columbia's fiery end. Now he has assembled a team of researchers to delve into the April 20 explosions that destroyed the Deepwater Horizon offshore drilling rig and caused the worst oil spill in U.S. history.

Toys, games, explosions! Engineers reach out to school kids

06/03/10 — BEAM, Berkeley Engineers and Mentors, got its start last year when a group of engineering students saw a need to organize science and engineering outreach to local schools. For years, engineering societies have sent members to K–12 schools to teach concepts and mentor younger students to meet their community service goals. But coordination overlapped or fell short, and lesson plans and best practices often disappeared or got lost in forgotten files. With Berkeley's characteristic can-do spirit, a group of society officers took the initiative to start a club that would remedy the problem.

Video: Deepwater Horizon rig: What went wrong?

05/21/10 MSNBC — Dr. Robert Bea of UC Berkeley came to the nation's capital this week with a message about what went wrong on the Deepwater Horizon rig. His preliminary findings, based on accounts from rig employees and others, suggest that the accident was the result of a series of mistakes and flawed decisions which had compromised safety.

Berkeley Engineering’s Robert Bea featured on 60 Minutes: Deepwater Horizon oil spill

05/16/10 60 Minutes — Scott Pelley reports on the Deepwater Horizon oil rig explosion that killed 11, causing the ongoing oil leak in the waters off of Louisiana. In his interview with UC Berkeley civil and environmental engineering professor and offshore drilling expert Robert Bea, Bea describes how his investigation has revealed disturbing technical, procedural and organizational failures leading up to the disaster.

Obama sends bomb inventor, Mars expert to fix BP oil spill

05/13/10 Bloomberg — U.S. Energy Secretary Steven Chu signaled his lack of confidence in the industry experts trying to control BP's leaking oil well by hand-picking a team of scientists with reputations for creative problem solving. BP has described conditions around its leaking offshore well as resembling those in outer space. Chu selected one scientist with experience operating on Mars, George Cooper, a civil engineering professor at UC Berkeley. Cooper once worked with the National Aeronautics and Space Administration to modify mining techniques on earth for use on Mars.

Oil rig blast caused by gas hydrates, Berkeley professor believes

05/12/10 Los Angeles Times — Robert Bea, a UC Berkeley engineering professor who is conducting an informal assessment of the Deepwater Horizon wellhead blast, said Tuesday that BP documents leaked to him indicate that contaminants in cement encasing the well were the initial cause of the explosion that led to the ongoing oil spill in the Gulf of Mexico.

New ways to drill, old methods for cleanup

05/10/10 The New York Times — As hopes dim for containing the oil spill in the Gulf of Mexico anytime soon, more people are asking why the industry was not better prepared to react. "They [oil industry engineers] have horribly underestimated the likelihood of a spill and therefore horribly underestimated the consequences of something going wrong," said Robert G. Bea, a professor at UC Berkeley who studies offshore drilling. "So what we have now is some equivalent of a fire drill with paper towels and buckets for cleanup."
