研究领域

Theoretical and Computational Chemistry

Research in my group focuses on the innovation of theoretical and computational methods to understand complex chemical and biological systems with biomedical and material applications. Deciphering sugar codes. Besides nucleotides and amino acids, sugars are considered "the third alphabet of life". With multiscale models and simulations, we try to understand the physical and chemical basis of how lection proteins recognize sugar codes. Knowledge obtained from this research could be applied to accelerate the development of medical solutions to treat viral infections and cancers. Reactivity predictions of glycosidases. Essential for all organisms, glycosidases are powerful enzymes to hydrolyze sugar polymers. Glycosidase enzymes are not only important therapeutic targets in our fight against many diseases, but also crucial catalysts for the food, textile, and paper industries as well as the emerging field of biofuel production. Based on hybrid quantum mechanics/molecular mechanics and induced-fit docking, this novel approach towards explaining and predicting glycosidase reactivity has potential applica-tions to guide the search for anti diabetic drugs and to advance protein engineering for chemoenzymatic reactions and biofuel production. Adaptive resolution assembly. By aiming to construct a fundamentally new approach to predict large bio-assemblies with various modules, we try to explore different possibilities to combine coarse-graining approaches, protein modeling technology, and high-performance computing to predict bio-assembly structures, with potential applications in drug discovery and biomaterials design.
