Want to schedule a meeting? Please check my calendar first to suggest an appropriate time.
I am an Associate Professor with the Robotics Institute and Computer Science Department at Carnegie Mellon University. My research interests span many topics across computer graphics and computer vision, but I'm particularly interested in computational imaging: a field that combines optics, electronics, and computational processing to capture or display new forms of visual information.
I received received my Ph.D. in Computer Science at the University of Toronto, and was a Banting Postdoctoral Scholar with the Department of Electrical Engineering at Stanford University. My work is the recipient of an NSF CAREER award, ACM SIGGRAPH Outstanding Thesis Honorable Mention award, various paper awards (ICCV 2025, CVPR 2025, SIGGRAPH 2023, CVPR 2022, CVPR 2014, and ICCV 2007), and best demo awards (ICCP 2023, CVPR 2015, and ICCP 2015).
