I am a theoretical physicist specializing in gravitation, quantum field theory, black holes, and cosmology. I also run the unixpackages.com project, which supplies open-source software packages to many organizations worldwide. I also moderated the Mathematica Community for Wolfram Research and support a software package called MathTensor for doing tensor analysis by computer. I have been doing astrophotography for about ten years. The group photo is of me (in the light blue shirt to the left) and colleagues at the Hawking Radiation Conference in Stockholm in 2015.
