 Petrik Clarberg joined the Real-Time Rendering team at NVIDIA Research in 2016. His current work is focused on systems and algorithmic research for real-time path tracing and new appearance models. Petrik's passion for graphics started with the 1990s demo scene. Before joining NVIDIA, he worked with graphics research in the industry for many years, co-founded a startup, and completed PhD studies at Lund University, Sweden.
