Research Topics

The primary goal of our work is to develop the theoretical framework needed to understand the behavior of molecules at the single-molecule level.  The idea is to extract quantitative information from raw experimental data (a photon trajectory or a force extension curve).  This requires a complete understanding of all complex microscopic processes involved and the ability to describe them mathematically.

Our second goal is to work with leading experimental groups and show them how to correctly analyze and interpret their experiments.  Our work helps them to obtain a detailed microscopic description of the specific biological processes under investigation.  Our work is significant because it opens the way for single-molecule experiments that provide both qualitative and quantitative answers to questions that scientists cannot address using conventional ensemble experiments.

Current Research

Our research aims to bridge the gap between theory and experiment.  We are developing the theories required to analyze and interpret both single-molecule optical (where the output is a sequence of photons with different colors) and mechanical (where the output is a force-extension curve) experiments.  The goal of our work is to extract both kinetic and thermodynamic information.  In addition, one of our long-term interests is to understand the role of diffusion in determining the rates of chemical reactions, including ligand binding and protein-protein association.
