Dr. Krishna K. Niyogi is a professor in the plant and microbial biology department at the University of California, Berkeley, and a faculty scientist in the molecular biophysics and integrated bioimaging division of Lawrence Berkeley National Laboratory. Dr. Niyogi studies photosynthetic energy conversion and its regulation in algae and plants. He is best known for pioneering genetic analysis of nonphotochemical quenching (NPQ) mechanisms that regulate light photosynthetic harvesting. Niyogi grew up in Oak Ridge, Tennessee, where his parents worked as biochemists at Oak Ridge National Laboratory. He received a BA in biology with honors from The Johns Hopkins University, an M.Phil. in biochemistry from the University of Cambridge, and a PhD in biology from MIT. He did postdoctoral research at the Carnegie Institution’s Department of Plant Biology at Stanford before joining the faculty at the University of California, Berkeley in 1997. He has received a Presidential Early Career Award for Scientists and Engineers, a Searle Scholar Award, the Melvin Calvin Award from the International Society of Photosynthesis Research, and the Charles Albert Shull Award and Fellow of ASPB Award from the American Society of Plant Biologists. He is a Howard Hughes Medical Institute-Gordon and Betty Moore Foundation investigator and a faculty scientist at Lawrence Berkeley National Laboratory.
