Research Interests

Computational structural biology

We study the catalytic molecular mechanism, structure-function relationship and regulations of protein macromolecules and their complexes, mainly using Molecular Simulations.

Computer-aided drug design

Combining to We predict the interactions between drugs molecules and targe proteins by computational biology, bioinformatics, and biostatistical analysis, so as to design or improve drug molecules.

Biophysics

Combining molecular simulations and mathematical analyses, we explore the features and their mechanisms of microscopic motions of water molecules, charged ions and phospholipids on the surface of proteins and in biomembrane.
