My undergraduate degrees are in Physics and Astronomy. My Master and Doctoral degrees are in Earth and Planetary Sciences. Basically, I am a Mineralogist and Geochemist who loves Math and Chemistry. My research work spans the breadth of the Solar System. You may wonder how that relates to Sustainability... Space is where the future of resource exploration lies and where we have the very real choice of extending either our best or our worst resource stewardship practices. Some of my colleagues call Lunar 3He "the Persian Gulf" of the 21st century. I am actively involved in making sure this is not so. There is also a very active conversation on mineral extraction from Near Earth Asteroids (NEAs), much of which is happening in the private sector, away from international treaties and any kind of environmental regulation.
