I am a PhD candidate in the School of Computer Science at Tel Aviv University, fortunate to be advised by Nadav Cohen.
My research interests broadly include the theoretical foundations and applications of modern machine learning. I aim to develop theories that shed light on how neural networks work, as well as bring forth principled methods for improving their efficiency, reliability, and performance.
During the summer of 2023 I interned at the Apple Machine Learning Research group. My research is generously supported by the Apple Scholars in AI/ML and the Tel Aviv University Center for AI & Data Science PhD fellowships.

Feb 24: New paper characterizes how the implicit bias of policy gradient affects extrapolation to unseen initial states, in linear quadratic control.
Jan 24: Two papers accepted to ICLR 2024: one identifying a vanishing gradients problem when using reinforcement learning to finetune language models and another analyzing length generalization of Transformers.
Sep 23: Two papers accepted to NeurIPS 2023: one on the ability of graph neural networks to model interactions and another on what makes data suitable for locally connected neural networks.
