About Me
I am a Research Scientist in the Real-Time Graphics group at NVIDIA, where my work focuses on generative content creation, with an emphasis on generative materials. Before joining NVIDIA full-time, I received my Ph.D. in Computer Science from Cornell University in 2026, advised by Prof. Steve Marschner. My Ph.D. research focused on realistic appearance modeling of materials, physically based rendering using wave optics, and techniques for creating expressive training data for generative material models. Before Cornell, I studied at the University of California, Los Angeles (UCLA), where I received a Bachelor of Science in Applied Mathematics and a Bachelor of Arts in Linguistics and Computer Science.
