I teach quantum mechanics and spectroscopy, integrated experimental chemistry, general chemistry, and an advanced seminar in biophysical chemistry. I also mentor students engaged in research for credit.
The research in my lab focuses on the use of magnetic resonance spectroscopy to investigate the structural and dynamic properties of membrane-bound molecules. Membrane proteins (which comprise 25-30% of all proteins) carry out many important biological functions including transport of material across membrane and acting as receptors. We are interested in developing and applying electron paramagnetic resonance (EPR) and nuclear magnetic resonance (NMR) spectroscopic techniques to the study of membrane associated proteins.
