I manage the Agents and Emergent Phenomena group at IBM Thomas J. Watson Research Center. I also share responsibility for IBM's data center energy management research strategy and a joint research program with the IBM Tivoli software group. My current research interests include autonomic computing, machine learning, and reducing energy consumption in large-scale computing systems. Earlier in my career at IBM Research, my team and I explored the application of analogies from biology and economics to massively distributed computing systems, particularly in the domains of autonomic computing, electronic commerce, and anti-virus and anti-spam technology. My team's research efforts on digital immune systems and economic software agents have been publicized in The Wall Street Journal, The New York Times, Forbes, Wired, Harvard Business Review, IEEE Spectrum, and Scientific American. In 2003, I co-wrote with Dave Chess an article in IEEE Computer entitled the "Vision of Autonomic Computing" that became the most widely cited article in the field of autonomic computing, and one of the most widely cited computer science articles of 2003 (according to CiteSeer). In 2004, I co-founded the International Conference on Autonomic Computing with Manish Parashar of Rutgers University and Salim Hariri of the University of Arizona. I received a BS from Princeton University in Electrical Engineering, also completing the Engineering Physics program. I received a Ph.D. from Stanford University in electrical engineering, along with a Ph.D. minor in physics. My doctoral research was an experimental and theoretical study of channeling radiation, a novel form of quasi-monochromatic X-ray and gamma-ray radiation emitted by relativistic electrons and positrons passing through aligned crystals. Afterwards, I spent two years at the Xerox PARC research center studying the nonlinear dynamical behavior of massively distributed systems of the future. I am an avid recorder player (playing all instruments in the family from sopranino down to contrabass). Sometimes I perform solo or with my quartet (La Spiritata) at local churches and restaurants. I'd like to juggle, ride the unicycle, and play tennis more often than I do.
