I am interested in ergodic homogeneous dynamics and related applications to equidistribution problems (gaps, pair correlations) of families arising from number theory in a global (number or function) field.

Doctoral student supervised by Jouni Parkkonen (Jyväskylän Yliopisto) and Frédéric Paulin (Université Paris-Saclay) since September 2022.
