Steve Pearce earned his Ph.D. from PTYS/LPL in 1995, working with Gene Levy. The title of his dissertation is "Core-mantle interactions resulting from sudden changes in the Earth's moment of inertia."
Steve sends the following update:
"I have been full-time faculty at Simon Fraser University (SFU), School of Computing Science, as a Lecturer. I am currently writing a textbook on the theory of technology. Other than that, I haven't been publishing.
I am loosely affiliated with the Dept. of Earth Sciences at SFU, and teach their PTYS course (for poets). I had a Skype interview with Tom Jones last year for the class---it was a hoot!
I had a company that was Kyoto oriented—what a farce that is—went under in 2003.
