Andrew C. Crowther joined the Barnard College Department of Chemistry in 2012. Professor Crowther is a physical chemist interested in the fundamental molecular processes and properties of nanomaterials.
Prior to joining Barnard, Crowther received his Ph.D. at the University of Wisconsin-Madison where he used ultrafast spectroscopy to study the role of molecular complexes in CN radical reactions in solution. During his postdoctoral research at Columbia University, Crowther used various spectroscopic techniques to study charge-transfer dynamics between graphene and absorbed molecular species.
At Barnard, undergraduate research students in the Crowther Laboratory use micro-Raman spectroscopy to study the vibrational structure of nanocrystals and the chemistry of carbon-based nanostructures. A major current focus is understanding how the vibrational properties of atomically precise nanostructures varies with nanostructure size and dimensionality.
