I am a PhD student in the Hebrew University of Jerusalem supervised by Prof. Tomer Schlank . I am currently a visiting student at the University of Chicago.
My mathematical interests lie in the realm of homotopy theory, with particular (though not exclusive) focus on chromatic homotopy theory, (∞,n)-categories, higher semiadditivity, topological quantum field theories, and representation theory.
