Seminars and Events

I coorganize with Karim Adiprasito, Harald Andrés Helfgott, Ryoshun Oba, and Arina Voorhaar the Combinatorics, Arithmetic and Geometry working group  at University of Sorbonne. Please feel free to contact me if you are interested to participate or give a talk. 

In the past I organized  the  KU-Jerusalem Lunch Seminar at Hebrew University of Jerusalem. 

CONFERENCE NEXT YEAR

In May 2026, I coorganize with Karim Adiprasito, Stavros Papadakis, Evita Nestoridi, Enis Kaya and Christos Tatakis a conference in Mytilini (Greece) related to Combinatorics, Geometry and Algebra. The registration is now open! Join us :-)
