A year ago I left Human Head and accepted a position on the rendering team at Epic Games. Since then we made the UE4 Infiltrator demo. I've worked on temporal AA, reflections, shading, materials, and other misc cool stuff for UE4 and games being developed here at Epic. I'm surrounded by a bunch of really smart, talented people, with whom it has been a pleasure to work.
Just this last week I presented in the SIGGRAPH 2013 course: Physically Based Shading in Theory and Practice. If you saw my talk and are interested in the subject but haven't looked at the course notes I highly suggest you follow that link and check them out as well as the other presenter's materials. Like previous years, the talks are only a taste of the content that the course notes cover in detail.
Now with that out of the way, hopefully I can start making some good posts again.
