I am an assistant professor in the School of Computing Science at Simon Fraser University. My research area is at the intersection of computer graphics and computer vision with strong connections to computational photography and machine learning. I work on image analysis and manipulation in terms of color, semantics, illumination, and material properties. I aim to connect the ways we understand and process digital imagery with human cognition and artistic expression.
My doctoral research has been on novel representations for images that allow easier analysis of photographs with applications to realistic image editing and movie post-production. I received my PhD degree in Computer Science from ETH Zurich under supervision of Marc Pollefeys. During my PhD, I spent a year at MIT CSAIL with Wojciech Matusik's group and 3 years at Disney Research Zurich.
PhD / MSc applicants: I have multiple open positions for the upcoming application cycle. Feel free to send me an email with your CV, transcipts, interests etc. However, due to the volume of applications, I am not always able to reply personally. If you'd like to work with me, you can list me as a potential supervisor at the SFU online application system (with deadline February 1).
