about
Our lab is doing research in the fields of theoretical/computational chemistry and biophysical chemistry. We are developing efficient computational methods and statistical mechanics tools to study the conformations of biological molecules in aqueous solutions, mechanisms of enzymatic reactions, and the solvation effects in chemical reactions. We are also interested in understanding the chromosome folding principle and gene expression regulatory mechansim. The lab is working on the simulation/theoretical studies of the following systems: (1) thermodynamics, dynamics and kinetics of electrolytes solutions (2) dynamics and spectra calculations for aqueous solutions (3) chemical/enzymatic reactions in solutions/at interfaces (4) the modeling of chromatin spatial structures and studying the relations between structures and important genome features (5) multiscale gene regulation mechansim in cell.
