Research Activities

Understanding the basic physical principles that govern the fold and function of proteins is paramount to predict and rationalize the biological activity of newly discovered proteins. To this end, we use computer simulations to study biological systems at the molecular level.

Currently the laboratory is engaged in three main directions of research.

  • We are studying the dynamic events involved in the folding and proper function of soluble proteins.
  • We are developing novel computational methods for the prediction of protein-ligand binding affinities to help in the discovery of new therapeutic agents (rational drug design).
  • We are studying the molecular mechanism of proton transport across biological membranes, a process which is essential to life itself (respiration, metabolism).
