A high powered lecture (total wattage obscured) Demonstrating refraction interactively! I am currently a research scientist at NVIDIA Research in Redmond, Washington.

Prior to my current position, I was an Associate Professor at the University of Iowa (2004-2014), a Visiting Professor at NVIDIA (2012-2013), and a Contractor at the US Army Research Lab (2011). Before joining the faculty at the University of Iowa, I studied at the University of Utah (PhD 2004) and the University of Minnesota (BS 1999).

As a research scientist, I am an active member of the computer graphics research community. I perform and publish novel research in real-time computer graphics, help organize conferences, serve on program committees and editorial boards, and review academic papers and grant proposals. My specialty is computer graphics, in particular interactive rendering of realistic images, though my interests and expertise include other realistic and interactive rendering problems, understanding how human perception affects rendering, general purpose computations on GPUs and other stream processors, efficient data structures and algorithms for highly parallel computations, and visualization.

Some recent interactive work includes improving alpha testing, foveated rendering in VR, stochastic order-independent transparency, NVIDIA's Hybrid Frustum Traced Shadows, decoupled coverage for antialiasing, participating media, and cloud-based rendering. Though as a faculty member, I also worked briefly in medical and information visualization and non-pinhole camera models.
