Secretary, US Department of Energy
Steven Chu is US secretary of energy. Chu has devoted his recent scientific career to the search for new solutions to our energy challenges and stopping global climate change. Since his appointment in 2009, Chu has been charged with helping implement President Obama’s ambitious agenda to invest in alternative and renewable energy, end our dependence on foreign oil, address the global climate crisis, and create millions of new jobs. Before serving as secretary, Chu was director of the 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 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. He is a distinguished scientist and co-winner of the 1997 Nobel Prize for Physics.
