Who am I?

I am currently a postdoc at the Technische Universität Graz in Austria, in the Institute of Analysis and Number Theory, belonging to the franco-austrian project Arithrand.

Previously, I worked at the Max Planck Institute for Mathematics, Bonn, Germany.

Before that, I was a MiLyon postdoc at the Institut Camille Jordan (ICJ), Lyon/St-Etienne, France.

I graduated at the University of Bristol, where my PhD supervisor was Julia Wolf. My doctoral thesis, which I defended in June 2018, was entitled "Linear, bilinear and polynomial configurations in function fields and the primes."

I also held a Lecturer position at the American University in Paris during Spring 2018.

Area of research

My research combines analytic, combinatorial, probabilistic and algebraic methods to solve arithmetical problems. It belongs to the area called arithmetic combinatorics, which has intense interactions with number theory, extremal combinatorics, harmonic analysis, ergodic theory, and various topics of theoretical computer science, such as error correcting codes, pseudorandomness etc.
