I have more than 20 years experience in computational chemistry method development and application to chemical and biological systems. In my position as CSO at VeraChem LLC I am responsible for design and oversight of the development of the company's VM2 software product for the calculation of protein-ligand binding free energies. I have recently guided the design and implementation of a new parallel processor version of VM2. My current focus is the integration of quantum mechanics energy potentials with the VM2 software package. In the past I have made significant contributions to the quantum chemistry package GAMESS, and have also implemented mixed quantum classical methods for simulation of proton transfer reactions in enzymes.
