This is an outdated page. My new homepage can be found here.

Researcher and team lead at the research department at Lightricks. My focus is on state-of-the-art algorithms and neural networks that can also run on mobile devices. Specifically interested in video processing.
Previously, I did a Phd in Computer Science at the Hebrew University of Jerusalem. My thesis was about video processing, geometry, and using deep learning to jointly learn from audio and video. My advisor was Prof. Shmuel Peleg.
