Etai Sella
Hi! I'm Etai, a PhD student at the School of Electrical Engineering, Tel-Aviv University (TAU) under the joint mentorship of Hadar Averbuch-Elor and Or Patashnik. My research focuses on editable and controllable generative AI.
I received my BSc. and MSc. in Electrical Engineering (Cum Laude) from Tel-Aviv University and spent a few years in the industry developing Computer Vision / Machine Learning related products.
I'm currently interning at NVIDIA, and have previously completed research internships at Meta (working with Yanir Kleiman) and Snap Research (working with Daniel Cohen-Or).
