Gil Cohen's homepage

Welcome! I am a professor in the Department of Computer Science at Tel Aviv University. My research focuses on pseudorandomness and derandomization, explicit constructions, and coding theory.

I am extremely grateful for the support of the ERC Starting Grant and the ISF Grant which fund my research.

Uninvited Talks: I started a playlist on my YouTube channel titled "Uninvited Talks," where I present some of my recent results. I find video lectures to be a valuable tool for learning about new results. Video lectures are often available from conferences (where talks are usually too short) or workshops (which have better lengths but are rare). Therefore, I decided to record talks on selected papers without the constraint of a harsh time limit, and with the bonus of improved audio and video quality. These talks will often be recorded as practice sessions for actual seminars or workshops, but I will allow myself to discuss the topics in more depth. I hope these videos will help you learn about my work. More importantly, I hope others will also start creating similar content!
