Student Research/Collaboration

The overall research interest of Dr. Xu is to understand protein function and structure relation. Dr. Xu’s lab is focused on developing a new computational algorithm, Triangular Spatial Relationship (TSR)-based, for protein 3D structure comparison, motif discovery, and protein – protein and drug – protein interactions. Dr. Xu is also interested in understanding the mechanisms underlying early fast processes of solar energy conversion into chemical energy.

Opportunities for Student Research/Collaboration:

Dr. Xu is  looking for Ph.D. students who are interested in bioinformatics or biochemistry.
