Theory and Computation
Our group explores the basic physics underlying a variety of biological processes ranging in scale from protein function at the molecular level to the collective motility of cells and organisms. We use theoretical methods from statistical mechanics, polymer physics and elasticity as well as simulation techniques including molecular dynamics, coarse grained Brownian dynamics, Monte Carlo simulations and agent based models . We also work in close collaboration with experimentalists. Our research spans three broad areas:
Biopolymer Structure and Dynamics
How do intrinsic disorder, chirality and surface interactions affect biopolymer structure and function?
How do teams of molecular motors accomplish transport on complex filamentous networks within the cell?
How do flocks/swarms/cell-clusters deal with individual variability and environmental disorder?
