I'm a PhD student at the Department of Computer Science at Tel Aviv University, advised by Prof. Yishay Mansour. During my PhD, I have worked as a research intern at Amazon and the Bosch Center for Artificial Intelligence. Prior to that, I obtained my B.Sc. in Mathematics and Economics from the Hebrew University of Jerusalem.
My research interest is in Machine Learning, with a focus on Reinforcement Learning and Online Learning.
