Multiscale simulations of biomolecular systems, Membrane permeation, Lipid droplets, ATP hydrolysis, AAA+ ATPases, Charge transport, Channels and Antiporters

Research

We study biological systems with computer simulations and a variety of multiscale computational methods. Although our interests are broad, we are currently focused characterizing biomolecular charge transport, membrane permeation, lipid droplets, pH-coupled processes, ATP hydrolysis and ATP-driven motion. In each of these projects we seek mechanistic insight by bridging time and length scales with electronic structure calculations, ab initio and classical molecular dynamics simulations, enhanced free energy sampling and kinetic modeling. We also work closely with experimental collaborators each step of the way, integrating experimental data, testing simulation results, predicting outcomes and ultimately synergistically characterizing each biomolecular process.
