Biography

I’m a Ph.D. student at the Computer Vision and Geometry Group of ETH Zürich working with Prof. Marc Pollefeys and Dr. Peter Kontschieder at Meta Reality Labs Zurich. I obtained my M.Sc. and B.Sc. degrees in Computer Science from RWTH Aachen University, where I worked with Dr. Jonathon Luiten and Prof. Bastian Leibe as a student research assistant. In 2020, I worked on a remote research project with Prof. Trevor Darrell at the University of California, Berkeley. My research focuses on reconstruction, rendering, and understanding of dynamic scenes.
