Wissam A. Saidi
Wissam Saidi received his B.S. in Physics from the Lebanese University and his Ph.D. (Physics) from the Ohio University. Following his graduation in 2003, he joined University of Pittsburgh in 2014, where he is associate professor in Mechanical Engineering & Material Science department. He received several awards including E. F. Hayes Graduate Research Forum Science Award in 2002 and Professional Development Fund Research Award in 2003.
The overarching goals of our research is to develop and use multiscale simulation tools to understand, predict, and design novel materials for applications in energy conversion and storage, surfaces and interfaces, spectroscopy, and nanoparticles. Our group has extensive expertise in different levels of theories in computational materials design that span a wide range of accuracy levels and length scales, including force-field, density-functional theory, quantum Monte Carlo and quantum chemistry methods.
