I'm an industrial physicist, but I've also been a university professor, and I still teach as an adjunct. My training is in solid state physics and nonlinear optical response of metal and semiconductor surfaces and interfaces. I work generally in optical physics and photonics.

I also have become a programmer of sorts. I have no formal programming training. For lab work and most in-house work I program in python with numpy, scipy, and matplotlib and often with the Enthought Tool Suite. I also contribute much code to applications that my company sells, and for those I program in Matlab, C++, and Objective-C.
