Welcome! I am a rising fifth-year PhD Candidate in Decision Sciences at INSEAD. In my first stream of research, I study how social dynamics influence individual and group decision-making biases, specifically focusing on overconfidence and underconfidence. In a second stream of research, I study how language influences decision-making using Large Language Models.

I am on the 2026-2027 Academic Job Market.

I received a B.A. in Philosophy, Politics, and Economics, as well as a B.A. in Economics and Management from the University of Lucerne in Switzerland.
