Senior Research Scientist @ Google Research

About Me

I am a Senior Research Scientist at Google Research, where I focus on making AI act rather than just speak — building agents that reason through code and collaborate across extended multi-turn workflows.

My academic journey includes completing a Ph.D. in Computer Science at the BIU NLP Lab, where I had the privilege of working with Prof. Ido Dagan, Prof. Jacob Goldberger, and Dr. Arman Cohan (from Yale). My previous education includes an M.Sc in Electrical Engineering under the supervision of Prof. David Burshtein, and a B.Sc in Computer Science and Electrical Engineering, both from Tel-Aviv University.

My research focuses on advancing reasoning and interactive agents by enhancing models' ability to plan, use tools, and execute decisions in software and interactive environments. In parallel, I am interested in studying model uncertainty, reliability, and interpretability.

I am always open to discussions and potential collaborations on these topics. If you have insights, questions, or are interested in exploring these areas together, please feel free to reach out.
