          I am a full professor in the Department of Biomedical, Industrial and Human Factors Engineering at Wright State University. I obtained my Ph.D. from Operations Research and Industrial Engineering Program at the University of Texas at Austin in 2003. My research focuses in the area of data mining, simulation, optimization, and business intelligence and the solution of practical problems in manufacturing, logistics, transportation, media and service management. These projects include a) crew scheduling and recovery for airlines, b) advertising allocation for media industry, c) equipment and personnel management for United States Postal Service, d) computational inventory simulation and optimization for Kroger (Pharmacy, Fresh Produce and General Mechadise), e) data mining and optimization in education (enrollment management), and f) business intelligence in customer relationship managment (Jewelry)

          More recently, our research in retail studies with Kroger Corp has drawn worldwide recognication. For example,  a) the Kroger Pharmacy Inventory Simulation and Optimization Project, "has reduced out-of-stocks by 1.5 million prescriptions, lowered inventory by more than $100M, and yielded additional revenue of more than $70M since Oct 2011. " and was selected as one of the six finalists worldwide, with BaoSteel, Chevron, Dell, Delta and McKesson, for the 2013 Franz Edelman Prize.  b) the project " Quevision Improve Front End Service Level Managment at Kroger Co. " was again selected as one of the twelve semi-finalists worldwide. These research are the testmonies of the high world-wide reputation of the research studies.  Besides these Kroger studies, our research was funded by the General Electric Company, Linear Power Corp.,  Peco II Corp.,Rittal Corp.,  David J. Joseph Corp., the United State Postal Service, and Continental Airlines, and the National Science Foundation.
