I am a researcher at the IBM T.J. Watson Research Center in Hawthorne, New York. I am working on sensor and agent-based methods for intelligent power management in data centers. To get a sense of the significance of IBM's work in this area, you may be interested in the April, 2008 study by McKinsey & Co. which projected that the world's data centers will surpass the airline industry in total greenhouse gas emissions by the year 2020. I am also working with IBM Tivoli to add energy management capability to our various systems management products.

I began working at IBM in 1994 and have been in Research since April, 2000. I have previously worked in the areas of Just-in-time Supply Chain Management, Help Center Diagnostics, Internet Search, Internet Security, eCommerce, Human-Computer Interaction research for eCommerce, Unstructured Information Management, and knowledge management applied to large scale systems management environments.

My academic interests are in the areas of discrete, combinatorial, and computational geometry. I am particularly attracted to simple to state problems in discrete geometry. For copies of some of my recent papers look here.
