Aaron Lefohn, Ph.D.
Director of Research
Bio:

Aaron Lefohn joined NVIDIA Research in 2013 and is leading real-time rendering research. Prior to joining NVIDIA, Aaron led an international real-time rendering and graphics programming model research team at Intel, the Advanced Rendering Technology team. He joined Intel in 2007 via Intel's acquisition of the computer graphics startup company, Neoptica. Neoptica was building new graphics programming models for Sony PlayStation 3 and other heterogeneous architectures. Before Neoptica, Aaron was a researcher at Pixar Animation Studios, creating interactive rendering tools for film artists. Aaron received his Ph.D. in computer science from UC Davis, his M.S. in computer science from University of Utah, and also holds an M.S. in theoretical chemistry.
