My research interests are in the broader area of pricing and revenue management, supply chain management and at the interface of operations and marketing. One stream of my current research is in the area of on-line retailing and in particular the effect of return policies together with other operational decisions on retailer profits. Another stream is on the impact of gray markets and parallel imports on supply chain performance and other operational decisions. From methodological and industry standpoint, I have been working on problems from high-tech, retailing and pharmaceutical industries using game theory and stochastic optimization.
