The laboratory employs techniques from biochemistry, chemical physics, and optics. We use femtosecond laser spectroscopy to quantify the spectra of motions by probing either the electronic transitions of a bound cofactor or ligand. Experiments on site-directed mutants or chemically modified proteins are used to determine the structural origins of the motions. We are also developing and employing microfluidics-based selection strategies on combinatorial libraries of red-fluorescent proteins to improve their photophysical properties and to generate new FRET-based sensors of metals and other analytes n vivo. Finally, we are extending the integration of spectroscopy with microfluidic flow-cytometry for development of new biophotonic functionality such as photoswitchable fluorophores.
