Computational biophysics and structural biology, Molecular simulation and modeling
My long-term goal is to investigate biomolecular functions through the multi-scale modeling of biomolecular dynamics at a wide range of length scales from whole molecules down to individual atoms. I will employ various structural models of biomolecules from coarse-grained to atomistic models. These complementary models will be welded coherently to achieve both efficiency and accuracy. I am interested in integrating computer modeling with experiments via collaborations so that my models are correctly parameterized by fitting experimental data, and then make informative predictions to guide future experiments. My ultimate goal is to computationally elucidate the molecular functions of various biomolecular "nanomachines" such as motor proteins (myosins, kinesins, polymerases and helicases).
