I have a BS in Physics from Carnegie Mellon University, and an MA and PhD in Astrophysics with a concentration in Plasma Physics and Controlled Thermonuclear Fusion from Princeton University. I work in the Defense software industry and live with my wife Sharon and our two European Burmese cream cats, Aristotle and Alexander, in Fairfax, Virginia, where we enjoy reading together, pampering the kitties, and traveling when we get the chance.
