I am a researcher at the IBM T.J. Watson Research Center in Hawthorne, New York. For the past several years I have focused my work on a range of energy efficiency problems. I try to find ways to make computer data centers and, more generally, buildings more energy efficient.
Recently I have turned my attention to improving the reliabily of solar irradiance forecasts. If we can improve the reliability of solar forecasts, power companies can better utilize their investments in solar capacity and thus reduce their reliance on fossil fuels. This work is supported by the U.S. Department of Energy's SunShot initiative.
Over the last two and a half years I have been working on a mobile robot for autonomously mapping, monitoring and managing the energy and thermal properties of a data center. Most recently we have outfitted the robot with a mobile RFID reader to give it fine-grained asset tracking capabilities. If you are interested in arranging for a robotic scan and detailed energy efficiency analysis of your data center, please contact IBM Systems and Technology Group's Lab Services, or in South America, our business partner, Redsis. A paper about our robot won the Best Paper award at the 2011 International Conference on Autonomic Computing (ICAC).
In 2012 I was named to my second consecutive term as an IBM Master Inventor. I worked on the strategy component of the IBM Jeopardy-playing program known as Watson, culminating in our celebrated victory over best-ever human players, Ken Jennings and Brad Rutter.
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, 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. Recently I have been applying geometric ideas to help solve problems associated with energy efficiency and robotics. For copies of some of my latest papers look here.
