Welcome! I am an Assistant Professor at LSE. My research is on economic theory.

Prior to London, I received my PhD from Toulouse and spent a (virtual) year as a post-doc at Princeton.

I am interested in how search frictions affect sorting in matching markets such as the labour market. I have studied the rationale behind sparse product lines when sellers restrict the variety of options, and worked on higher-order beliefs—beliefs about other players' beliefs—and their manipulation in games of incomplete information. More recent work focuses on menu pricing in oligopolistic and competitive environments.
