Dr. Gray is a physicist with expertise in computational modeling, having applied his skills and experience in this area to a variety of topics ranging from the study of materials used in semiconductor manufacturing, to the stochastic evolution of cancer cells. At Exponent Dr. Gray uses his multidisciplinary skills in theoretical physics, experimental physics, and material science to assist clients with a variety of engineering challenges including intellectual property litigation, failure analysis of mechanical components, and the investigation of industrial accidents.

Performed Density Functional Theory investigations of the semiconductor Rhenium Disulfide under pressure. Analyzed phase transitions between direct and indirect bandgap phases of this material. Helped to develop quantum and thermodynamic theory to describe the stable phases of this material as they change with pressure and temperature.
Developed software for stochastic computational simulations of cancer cells and their interactions. Developed a mathematical model to determine the probability of a cancer mutation taking over a population of healthy cells as a function of interactions and spatial location.
