Professional Background
Education: 
Ph.D. in AstroGeophysics from the University of Colorado in 1982
Research Interests: 
My research focuses on the evolution of the solar system and the origin of life. I'm also actively involved in planning for future Mars missions including human exploration. I have been involved with polar and desert research, traveling to the Antarctic Dry Valleys, the Atacama Desert, the Arctic, and the Namib Desert to conduct research in these Mars-like environments.
