Kelly Knutsen - Postdoc
Kelly Knutsen received his B.A. in Chemistry with a concentration in Science, Technology, and Public Policy, from Carleton College in Northfield, Minnesota, in 1999. During the summer of 1998 in Prof. W. Ron Gentry’s group at the University of Minnesota, Twin Cities, he studied the structure of amorphous ice and its implications on the atmospheric chemistry of polar stratospheric clouds. In 2005 he received his Ph.D. in Physical Chemistry from the University of California, Berkeley, working with Prof. Richard J. Saykally. There he developed a high spatial and spectral resolution microscope employing chirped femtosecond pulses and nonlinear optical techniques to study a range of systems from interplanetary dust particles to materials to biological samples.
Dr. Knutsen joined NREL in August 2005 as a postdoc researcher. He works jointly with the Heben and Nozik groups to perform time-resolved studies of carrier dynamics in carbon nanotube, inorganic nanocrystal, and organic polymer systems.
