Research interests

Our group uses computer modeling and simulation to study and to engineer structure-function relationships in biomolecules. We use state-of-the-art simulation techniques, including computational protein design, molecular dynamics, continuum electrostatics, and free energy perturbation techniques, and a significant portion of our effort is directed at the development of new techniques as new needs arise. We are especially interested in protein engineering, protein-ligand recognition, and the inverse protein folding problem. We have taken part for many years in the development of free energy perturbation techniques for proteins, and these techniques are now maturing into a reliable and remarkable tool. Recent applications to aminoacyl-tRNA synthetases have provided insights into the translation of the genetic code. Protein design using directed evolution is an important research direction in the group. We have developed the Proteus software package for physics-based computational protein design. BOINC logo
