Summary

My lab develops new physical tools to study molecules and cells, and we apply these tools to make new measurements. We combine nanofabrication, optics, microfluidics, electronics, and biochemistry to generate data; and we apply statistics and physical modeling to understand the data. Current projects include: development of nanofabricated devices for trapping and studying single biomolecules in free solution; development of fluorescent voltage-indicating proteins; studies on optical spectroscopy in highly contorted electromagnetic fields; experiments on magnetically sensitive photochemical reactions; and studies of the mechanochemistry of biological hydrogels.
