Topological Sarnak conjecture and multiple ergodic averages for nilpotent groups (HFRI - Greece)
Bio
Graduated with a degree in Mathematics and Physics in 2015 from UB. Obtained my PhD in Mathematics in 2021 at the Ohio State University, under the supervision of Vitaly Bergelson. I held a six month postdoctoral position in the Nikolaus Copernicus University (UMK) in Poland, under the supervision of Mariusz Lemańczyk. In 2023 I obtained the Masters degree in teaching of mathematics in high schools. Before arriving at UCM in 2025 I had substitute professor positions in URV, UPF, and UAB from 2023 until the end of 2025.
Research interests
