Summary Information

I am a Computer Scientist in the Autonomous Systems & Robotics Group
in the Intelligent Systems Division of the Exploration Systems Directorate
at the NASA Ames Research Center.

My Research Interests are:

  • Autonomous Systems
  • Machine Learning
  • Data Mining
  • Probabilistic Networks
  • Stochastic Prediction Sytems
  • Complex Adaptive Systems
  • Evolutionary Computation
  • Robotics
  • Dynamical Systems
  • Sensorimotor Integration
  • Remote Sensing
  • Vision

Projects

  • Personal Satellite Assistant
    A softball-sized robot being developed to help crew members inside the Space Shuttle and Space Station.

  • Deep Space One Remote Agent Experiment
    We completed a successful demonstration of the Remote Agent when it controlled Deep Space One during May, 1999. Subsequently, the Remote Agent was co-winner of the 1999 NASA Software of the Year Award.

  • Intelligent Deployable Execution Agents

  • Human-Centered Autonomous Agents
