Biographical Sketch
Jason Lawrence received his Ph.D. from Princeton University in 2006. His research interests in computer graphics include the acquisition and representation of realistic surface appearance, physically-based rendering algorithms, and computational photography. His has coauthored eight refereed papers, and his hobbies include stand-up comedy.
Research
Lawrence's research explores techniques for integrating empirical data into the computer graphics pipeline. The goal of his work is to enable artists, designers and hobbyists to easily acquire and incorporate measurements of complex real-world phenomena into synthetic imagery. Reaching this goal will require addressing open research problems related to the efficient acquisition, representation, storage and retrieval of high-dimensional datasets commonly encountered in graphics. He introduced several new representations for surface reflectance functions derived from measured data. He is investigating generative probabilistic models for representing a broader class of light transport functions.
