Samuli Laine, Ph.D.
Principal Research Scientist

Samuli Laine joined NVIDIA Research in 2007 after receiving his Ph.D. at Helsinki University of Technology. His research interests have ranged from shadow and visibility computation to signal processing and efficient representations, authoring, acquisition, and rendering of extremely detailed 3D content. Dr. Laine has had a pivotal role in NVIDIA's ray tracing research, especially related to the implications of high-latency, wide-SIMD hardware.
