Note: I am no longer with the University of Utah. I'm still living in Utah, and still occasionally work with some of the people there, but I am no longer a full-time professor there, and thus cannot advise/take on any students.

Short Bio

Ingo Wald is a director of ray tracing at NVIDIA, and adjunct Assistant Professor at the University of Utah. He received his master's degree from Kaiserslautern University and his PhD from Saarland University (both on ray tracing-related topics). He then served as a post-doctorate at the Max-Planck Institute Saarbruecken, as a research professor at the University of Utah, and as technical lead for Intel's software-defined rendering activities. Ingo has played a lead role in multiple widely used software projects (such as Embree, OSPRay, or OWL), has co-authored more than a hundred papers, and has received multiple awards for his work, including a Technical Achievement Award of the Academy of Motion Pictures for Embree. His interests revolve around all aspects of efficient and high-performance ray tracing, from visualization to production rendering, from real-time to offline rendering, and from hard- to software.

News
