I work in harmonic analysis, arithmetic
combinatorics and discrete geometry.
During the past few years, my main research thrust has been the study of
the structure of translational tilings, focusing particularly on the
wellknown periodic tiling conjecture.
I have also been investigating other problems such as the Collatz
conjecture, Fourier decoupling for fractals, and problems of additive
combinatorics and ergodic Ramsey theory.
