Steven Chu Career

After obtaining his doctorate he remained at Berkeley as a postdoctoral researcher for two years before joining Bell Labs, where he and his several co-workers carried out his Nobel Prize-winning laser cooling work. He left Bell Labs and became a professor of physics at Stanford University in 1987, serving as the chair of its Physics Department from 1990 to 1993 and from 1999 to 2001. At Stanford, Chu and three others initiated the Bio-X program, which focuses on interdisciplinary research in biology and medicine, and played a key role in securing the funding for the Kavli Institute for Particle Astrophysics and Cosmology. In August 2004, Chu was appointed as the director of the Lawrence Berkeley National Laboratory, a U.S. Department of Energy National Laboratory, and joined UC Berkeley's Department of Physics and Department of Molecular and Cell Biology. Under Chu's leadership, the Lawrence Berkeley National Laboratory was a center of research into biofuels and solar energy. He spearheaded the laboratory's Helios project, an initiative to develop methods of harnessing solar power as a source of renewable energy for transportation.

Chu's early research focused on atomic physics by developing laser cooling techniques and the magneto-optical trapping of atoms using lasers. He and his co-workers at Bell Labs developed a way to cool atoms by employing six laser beams opposed in pairs and arranged in three directions at right angles to each other. Trapping atoms with this method allows scientists to study individual atoms with great accuracy. Additionally, the technique can be used to construct an atomic clock with great precision.

At Stanford, Chu's research interests expanded into biological physics and polymer physics at the single-molecule level. He studied enzyme activity and protein and RNA folding using techniques like fluorescence resonance energy transfer, atomic force microscopy, and optical tweezers. His polymer physics research used individual DNA molecules to study polymer dynamics and their phase transitions. He continued researching atomic physics as well and developed new methods of laser cooling and trapping. As of 2022, he is the President of the Scientific Committee of ESPCI Paris.
