Research Focus

Biophysical Chemistry

We develop and apply single-molecule spectroscopic methods to visualize dynamic rearrangements of biological machines. One project is aimed at understanding how the multiple enyzymatic activities of DNA polymerases are physically coordinated to ensure accurate and efficient replication of DNA. Another project is focused on the role of protein conformational dynamics during the signaling activity of G protein-coupled receptors. Single-molecule methods are also being used to dissect the assembly pathway of multi protein-RNA complexes formed during the life cycle of HIV-1.
