About

I recently finished my PhD in mathematics at the Hebrew University, under the supervision of Tomer Schlank and Lior Yanovski. Within math, my research interests are mostly in chromatic homotopy theory, algebraic K-theory, (spectral) algebraic geometry, higher category theory, and their interplay through the redshift conjecture.

Aside from math, I have an extensive background in software engineering and cyber-security research, and I am interested in various other subjects such as physics and statistics. I am also an active member of the effective altruism community. In my free time I enjoy hiking long-distance trails.

For more information, see my curriculum vitae.
