About Me

I completed my PhD at the Hebrew University of Jerusalem in October 2023 as part of the ELSC International Graduate Program, under the supervision of Prof. Daphna Weinshall. My PhD thesis focused on studying the learning dynamics of deep networks from a data-centric perspective. Currently, I am a post-doctoral researcher at KU Leuven in the ESAT-PSI lab, working with Prof. Tinne Tuytelaars. My current research extends into continual learning, exploring both the learning and the forgetting dynamics of deep networks.
