John Yi is originally from South Korea. He graduated with a PhD in Physical chemistry from University of Pittsburgh in 2005. His research was concentrated on gas phase studies of biologically relevant molecules and their various complexes.  These studies gave detailed information of a molecule’s stable geometry(s) or the structure of solvated molecules. After completing the degree he did postdoctoral work at the Ohio State University in 2005-06, with Terry Miller in the Department of Physics.  He also spent a short time at Stanford University in Department of Mechanical Engineering as postdoctoral fellow. He joined the faculty at the Winston Salem State University (WSSU), Department of Chemistry in 2006.   At WSSU, Yi’s research program in molecular spectroscopy is interested in developing spectroscopy techniques for the study of biological molecules, chemical and explosive agents in the gas phase.
