I first encountered computational mathematics as an undergraduate summer student coding numerical relativity simulations in FORTRAN. As graduate student I switched to MATLAB, developing DSP methods for biomedical acoustics.

Professionally, I use MATLAB extensively to prototype data processing algorithms, typically to be implemented in C++ production code. I very much appreciate MATLAB's ease of use to design, debug, test and run a wide variety of data processing algorithms, and that it gives me a host of sophisticated mathematics and graphics tools at my fingertips.

Fields in which I've worked are digital radiographic imaging, distributed acoustic sensing, remote gravitational sensing, scientific optics and medical physics.

Professional Interests: Digital Signal Processing, Image Processing, Mathematical Physics, Machine Learning, Algorithm Design
