I am a computational physical chemist. My research is in the areas of force field building and applications. Special attention is given to creating polarizable force fields for organic and biophysical systems, including proteins and protein-ligand complexes. I teach classes in physical, computational and general chemistry. Simulations of proteins is very important in biomedical research because proteins play crucial role in a large number of biological phenomena, both benign and harmful. But the results of these simulations are only as good as the quality of the "nuts and bolts" used in modeling the molecules, and these "nuts and bolts" are what is usually termed "the force field". My research is focused on understanding the underlying mechanics of the molecular interactions, creating tools for simulating big systems and on testing and applying such tools. I believe that formal undergraduate teaching is a way of forming rigorous understanding and skills in the area of basic scientific knowledge. The classes taught at the graduate level can also be used to introduce a broader perspective about actual and possible applications of this basic knowledge, and research in the lab, both graduate and undergraduate, leads to creative application of the acquired understanding and skills.
