Harold Wickes Hatch

My research interests include the development of new molecular simulation methods, coarse-grained models of monoclonal antibodies, self-assembly of patchy particles, protein stability and hydrophobic hydration. My curriculum vitae may be found on my personal website ( Please contact us if interested about undergraduate or postdoctoral fellowships that are offered within our group.

The Free Energy and Advanced Sampling Simulation Toolkit (FEASST) is a free, open-source, modular program to conduct molecular and particle-based simulations with flat-histogram Monte Carlo and molecular dynamics methods.

The Standard Reference Simulation Website is an ongoing project whose aim is to provide well-documented simulation results for a variety of systems and from various simulation techniques.
