Isay Katsman

I'm a Computer Science MS student at Cornell University. I recently finished a Math and CS double major as an undergrad at Cornell advised by Prof. Serge Belongie.

My research interests are machine learning and geometric deep learning, particularly in the context of applied differential geometry and adversarial examples.

I am actively seeking PhD advisors for Fall 2022.
