About Me
I am a Software Engineer on the Perception Team at Google Research.

I recently completed my PhD working with Prof. Shmuel Peleg as part of the HUJI Computer Vision Lab. My main research interests are applications of computer vision using deep learning, particularly in the area of sight and sound-based video analysis.
