I have a doctorate in physics. My research specialities are theoretical and experimental nonlinear dynamics, as in chaos, and biophysics. I do freelance computer work and occasionally teach.
My professional memberships:
American Physical Society (APS), including the Division of Biophysics and the Division of Computing
IEEE, including the Circuits and Systems Society and the Lasers and Electro-Optics Society (LEOS)
