John E. Crowell is a Professor of Chemistry and Biochemistry at the University of California, San Diego. He received his B.S. in chemistry from the University of Illinois, Urbana, in 1979 and his Ph.D. in physical chemistry under the direction of G. A. Somorjai from the University of California at Berkeley in 1984. He joined the faculty at the University of California, San Diego, in 1986 after postdoctoral research with J. T. Yates, Jr., and D. M. Hercules at the University of Pittsburgh. His research program is primarily focused on surface processes that govern thin film formation, including the kinetics of chemical reactions at semiconductor surfaces, the mechanism of dielectric and semiconductor thin film growth, photo-assisted deposition and desorption processes, and biomolecule analysis using nanoporous Group IV materials. He has taught often in the areas of General Chemistry, Physical Chemistry, Surface Processes, and Spectroscopy.
