Doug Hamilton grew up in Alaska chasing moose and being chased by them. He left the state to attend two of the great southern universities Stanford and Cornell, worked overseas for a few years in Heidelberg Germany, and is now a professor at the University of Maryland. Doug's scientific research focuses on planetary dynamics and the origin of the Solar System. He has studied the rings of Jupiter, Saturn, Uranus, and Neptune, the orbital histories of satellite systems, and the curious interactions of extra-solar planets. Doug has a strong interest in undergraduate teaching and has led a team of undergraduates in producing an interactive set of online tools called the Astronomy Workshop. Tools in the Astronomy Workshop animate planetary orbits, show what happens when an asteroid strikes the Earth, and generally allow users to explore the Solar System from the comfort of home. The Astronomy Workshop is available to the public at http://janus.astro.umd.edu.
