Research Overview

Dr. Yumin Li's research interests focus on chemically and biochemically important systems.

Knowledge of the mechanism of protein-protein and protein-ligand interactions is significantly important, which serves as the basis of structure-based drug research. To investigate protein-protein interaction and protein-ligand interactions, the classical mechanics based molecular dynamics simulations are carried out on the interesting systems using highly efficient multiple nodes and multi-processors computer cluster.

Another research interest is understanding the photochemical reaction mechanism of atmospherically important species such as NxOy.  Such investigations will definitely help to understand the atmospheric O3 depletion process. Quantum mechanism based high level ab initio methods, mainly multi-reference configuration methods (CASSCF and MRCI), are used to study the excited state of atmospherically important species.
