The research in my laboratory is focussed on the biophysical properties of a diverse family of photoactive membrane retinal-binding proteins, rhodopsins. Rhodopsins are found both in bacteria and higher organisms, and serve either as light-driven ion pumps (important in bioenergetics) or photosensors (important in microbial motility, animal vision, and circadian clocks). We combine modern biophysical methods (including time-resolved spectroscopy in the visible, FTIR spectroscopy, SPR, NMR, and Raman spectroscopy) with molecular biology and biochemistry.
