I am a research professor at The George Washington University. My research area is multi-wavelength observations of magnetic cataclysmic variables with a current focus on radio observations. I have been developing scientific software for over 40 years. My first project was developing a data acquisition program for an optical polarimeter at the South African Astronomical Observatory. The program was written in the C programming language for an IBM AT personal computer. In the mid-90s, a colleague and I advocated for Python to be the primary data analysis language for astronomy. As a result, I spent a number of years at the Space Telescope Science Institute developing core Python packages for scientific computing and astronomy, e.g., numerical python/numpy, PyFITS, and matplotlib. In the last five years, I have migrated from Python to the Julia programming language, because I believe it is the future of scientific programming. I am currently developing various core Julia modules and applications for astronomy. Two such modules are the Astrometry module for precise time and position calculations, and Visfit for analyzing radio interferometric data.
