  • Ph.D., Psychology, Stanford University, 1992
  • MA, Psychology, UC San Diego, 1987
  • MPhil, Computer Speech and Language Processing, Cambridge University, 1986
  • BA, Mathematics, Oberlin College, 1985

Research Interests

  • Simple heuristics for decision making, and how they capitalize on the structure of information in environments
  • Evolution of behavior (experimental approaches to evolutionary psychology and computer simulations of simple organisms adapting to different environmental structures, both physical and social)
  • Emergence of environment structure through interactions of populations of agents following simple behavioral rules
  • How people and other animals search for resources in time and space, from sequential search for mates or jobs to foraging for prey or parking spaces
  • Artificial life approaches to music
  • Making decisions about food and eating, and cognition of consumption
