I am an assistant professor in Industrial Engineering at Georgia Tech. I am interested in the theory and applications of supply chain and logistics models primarily involving transportation and inventory decisions, and in related optimization topics. The methodologies I use to study these problems include linear, mixed-integer and dynamic programming.
