Gary Hart, PhD, is an instructor of mathematics at Pitt-Greensburg. His specific areas of interest are optimization and numerical analysis. Dr. Hart's most recent research projects and thesis have involved using optimization for the simulation of nonsmooth rigid multibody dynamics with contact and friction. This allows him to blend optimization and numerical analysis with his general areas of interest, namely, functional analysis, linear algebra, and differential equations. Dr. Hart is faculty advisor for Math Club and the Diversity Student Coalition. He also serves on the President's Advisory Committee on Diversity, Faculty Welfare Committee, Math Placement, and the Technology Committee.
