Research: Computational Chemistry

Our research work focusses on the development of ab initio molecular dynamics techniques and their applications in studying chemical reactions in solution, enzymes, and various solid catalysts. We work on the development of new methods for free energy calculations, novel hybrid quantum mechanics/molecular mechanics methods, and developing accurate transferable all-atom force fields. Our interest is also on the understanding of the mechanism of antibiotic resistance due to β-Lactamase, predicting mechanism and kinetics of catalytic reactions involving zeolites, and design of new polyimides.
