Mathematician -- PhD 1992
University of Wisconsin-Madison
Astronomy is my hobby. Kind of an obsession at times! Not so much about where to point my telescope, but more learning about exotic places.
I started out in Topology and Analysis at Texas Tech, then went to Wisconsin and switched to Applied Math. Started working on a PhD thesis in General Relativity, then changed to Dynamical Systems, and ended up with a PhD in Differentiability Theory. Studied a lot of Classical Physics.
I also worked as a radar engineer in the missile defense industry for 10 years. This gave me an appreciation of the "real world."
Other hobbies: genealogy, coin collecting, science fiction, philosophy, hiking.
