Chris Wyman joined NVIDIA Research in 2012, and works from the Redmond, WA office in the real-time rendering research group.  Before joining NVIDIA, he was an associate professor of computer science at the University of Iowa. He has a Ph.D. in computer science from the University of Utah and a BS from the University of Minnesota.  Broadly, his research focuses on realistic, real-time rendering algorithms, especially related to lighting, global illumination, shadows, participating media, materials, and related issues.

Recent research explores uses of real-time ray tracing given very limited ray budgets.  This led to powerful stochastic sampling techniques like ReSTIR and NVIDIA's RTXDI SDK, which builds on insights gleaned from stochastic and deterministic filtering for post-process reconstructionorder-independent transparency, antialiasing, alpha-testing, and geometry.  He has also spent time evangelizing real-time ray tracing, including in SIGGRAPH courses and DirectX Raytracing code tutorials.
