RESEARCH INTERESTS
I aim to understand how humans learn to make decisions at the behavioural, computational and neural levels. Recently I have started investigating Large Language Models' cognitive and decision-making abilities. I also enjoy questioning the epistemological and methodological foundations of cognitive science and artificial intelligence research. In my "spare time", I am writing a book on "decision making" with Valentin Wyart for Oxford University Press (a "very short introduction" that is proving not so quickly written as originally thought...).
