About Me
Application of data driven optimization and analytical models to a wide variety of practical operational problems. Current research is primarily focused on supply chains and healthcare systems. In the supply chain area my research interests are on warehousing and distribution operations for online retail supply chains. In the healthcare systems area my research interest is specifically on modelling the relative productivity of U.S. hospitals. My research has been published extensively in leading journals and the was research sponsored by many agencies including the National Science Foundation, US Department of Energy and US Army Research Office.
