Dr. Steven Chu served as the Secretary of Energy from January 21, 2009, to April 22, 2013.

Dr. Chu was charged with helping implement President Obama's ambitious agenda to invest in clean energy, reduce our dependence on foreign oil, address the global climate crisis, and create millions of new jobs.

Dr. Chu is the co-recipient of the Nobel Prize for Physics (1997) and received numerous other awards. He has devoted his recent scientific career to the search for new solutions to our energy and climate challenges - a mission he continues with even greater urgency as Secretary of Energy.

Prior to his appointment, Dr. Chu was the Director of the Department of Energy's Lawrence Berkeley National Lab, where he led the lab in pursuit of alternative and renewable energy technologies. He also taught at the University of California as a Professor of Physics and Professor of Molecular and Cell Biology. Previously, he held positions at Stanford University and AT&T Bell Laboratories.

Dr. Chu's research in atomic physics, quantum electronics, polymer and biophysics includes tests of fundamental theories in physics, the development of methods to laser cool and trap atoms, atom interferometry, and the study of polymers and biological systems at the single molecule level. While at Stanford, he helped start Bio-X, a multi-disciplinary initiative that brings together the physical and biological sciences with engineering and medicine.

The holder of 10 patents, Dr. Chu has published ~250 scientific and technical papers. He remains active with his research group and has recently published work on general relativity, single molecule biology, biophysics and biomedicine, and on scientific challenges and opportunities in clean energy. Over 30 alumni of his research group have gone on to become distinguished professors and have been recognized by dozens of prizes and awards.

Dr. Chu is a member of numerous honorific societies including the National Academy of Sciences, the American Philosophical Society, the Royal Academy of Engineering, the Academia Sinica, the Korean Academy of Sciences and Technology, and is an honorary member of the Institute of Physics, the Chinese Academy of Sciences, and a Lifetime Member of the Optical Society of America. He received an A.B. degree in mathematics, a B.S. degree in physics from the University of Rochester, and a Ph.D. in physics from the University of California, Berkeley, as well as 23 honorary degrees.

Dr. Chu was born in Saint Louis, Missouri in 1948. He is married to Dr. Jean Chu, who holds a D.Phil. in Physics from Oxford and has served as chief of staff to two Stanford University presidents as well as Dean of Admissions. Secretary Chu has two grown sons, Geoffrey and Michael, by a previous marriage.
