Research Interests

My research interests mainly focus on using state-of-the-art computational methods and fundamental principles to investigate mechanistic insights into enzymatic reactions. The reaction mechanisms and the origins of reactivity and selectivity are elucidated, which can help to rationalize experimental findings and to guide the rational design of enzymes for desired activities. My current works are in close collaborations with experimental groups for better understandings of the questions of interests.

◆ Quantum Chemical Modelling of Mechanism and Selectivity of Enzymatic Reactions

◆ Theoretical Investigation of Enzymes Using QM/MM Methods

◆ Theoretical Calculations for Protein-ligand Binding Free Energy

◆ Computational Studies for Reactivity and Selectivity of Homogeneous Catalysis
