Principal engineer, Sony Pictures Imageworks.

Professional software engineer and researcher for 20 years, specializing in computer graphics for animation and visual effects. I mainly develop in C++ on Unix variants (Linux and OS X), but occasionally use Windows, Python, Perl, shell scripts, as well as programmable extension languages for a variety of packages.

I am the administrator of two open source projects widely used in the visual effects and animation industry: OpenImageIO (https://github.com/OpenImageIO/oiio) and Open Shading Language (https://github.com/imageworks/OpenShadingLanguage).
