Stephen A. Cooke

Professor of Chemistry

I am interested in the interaction between light and matter.  Photons with frequencies close to those received by an FM radio are useful for probing the structural landscapes of large molecules. I build and use spectrometers that utilize these frequencies. During the course of studying large molecules I often observe unique, microscopic features pertaining to a molecules structure which I then characterize. The information I obtain is useful in the fields of biochemistry, chemistry, and physics.
