Dr. Mahin Hemmati received a Ph.D. degree in computational chemistry at Arizona State University in 1996. She also has B.S. and M.S. degrees in chemical engineering from University of Nevada, Reno. Dr. Hemmati's research focuses on applying computer simulation methods to study the physical properties of liquid, glass, and crystal phases. In her current project, Dr. Hermmati uses molecular dynamics simulations to study liquid-liquid transitions and the existence of a critical point in rigid-ion silica (models). In this study, the phase equilibria, structure and dynamical behavior of silica models are compared with those of water, another tetrahedron-forming liquid that possesses interesting and rich phase diagrams not unlike some silica models.
