A Nobel Prize recipient in Physics (1997), Dr. Chu was appointed by President Obama as the 12th Secretary of Energy and sworn into office on January 21, 2009.  Prior to his appointment, Dr. Chu was director of Department of Energy's Lawrence Berkeley National Lab, and professor of Physics and Molecular and Cell Biology at the University of California.  He successfully applied the techniques he developed in atomic physics to molecular biology, and since 2004, motivated by his deep interest in climate change, he has recently led the Lawrence Berkeley National Lab in pursuit of new alternative and renewable energies.  Previously, he held positions at Stanford University and AT&T Bell Laboratories.
