He also holds a joint appointment at NASA Jet Propulsion Laboratory (JPL), serving on the JPL Climate Change and Energy Committee. He has over 16 years of experience in renewable energy technology; so he was working in alternative energy long before it was "cool," and has had the pleasure of working in fields of ocean, wind, and solar energy. His research group works on new blade designs for wind energy systems and new methods for storing solar thermal energy for baseload power. He currently serves as the Chief Scientist for WindStream Technologies, Inc., a micro-wind energy company.
