I am a PhD student at the Department of Mathematics in the Weizmann Institute of Science, studying under Prof. Alex Lubotzky and Prof Uri Bader.
I am also a Clore Scholar.
During fall 2023, I visited Prof. Adrian Ioana at UC San Diego as a visiting graduate student.
Previously, I was a Masters student at the Hebrew University of Jerusalem, where I studied under Prof. Alex Lubotzky.

Research Interests:
Broadly speaking, my main interest is Group Theory and its interactions with Operator Algebras and Dynamics. I am also increasingly interested in applications of the above to Quantum Information Theory and Theoretical Computer Science.
Currently, my research focuses on the emerging topic of Stability in Group Theory, and its relation to Approximation Properties of Groups. More specifically, I am interested in various forms of Hilbert-Schmidt stability for different classes of groups, as well as its quantitative aspects. This has lead me to think about character theory of infinite groups, measured group theory, rigidity and structure of lattices in Lie groups.

Current:
I am currently co-organising the Midrasha on Groups in Weizmann, together with Guy Solomon. This is our flagship group theory seminar, where we meet on Monday mornings for a learning seminar, and afternoons for a research seminar.
Fall 2024-2025, the learning seminar was on measured group theory
Spring 2024-2025, the learning seminar was on Discrete Groups, Expanding Graphs and Invariant Measures.
Fall 2025-2026, (T-BA).
More information as well as recordings can be found on our website.
Past:
During Fall 2023, I co-organised the Midrasha on von Neumann Algberas together with Adam Dor-On in the Weizmann Institute. This was a learning seminar (style Midrasha) on the basic theory of von Neumann algebras, as well as more advanced techniques in the case of II_1-factors. The list of lectures are listed in the seminar breakdown.
During 2021-2022, I organized the Topics in group theory student seminar at HUJI together with Michael Chapman. Recordings and information about future and past lectures are available in the above link.
During 2018-2021, I co-organized and co-founded the Nivtan (Walrus) and Penguin seminars at HUJI, together with Yonathan Bachar, Michael Glasner and Ido Karshon. These were informal meetings that served as a friendly stress-free environment for motivated undergraduate/beginning graduate students at HUJI to talk about mathematics they like and wanted to share with others.
