Doctoral Researcher, Aalto University

I’m a doctoral researcher working at the intersection of Human-Computer Interaction (HCI), digital mental well-being, and computational social science. I use mixed methods to explore how digital traces and online behaviors relate to loneliness, social media use, and emotional polarization.
