I am a historian and philosopher of mathematics. I am currently a (fixed-term)
researcher at the École Normale Supérieure (Paris), within the
ITEM research group, in a
research project on Nicolas Bourbaki. I
studied mathematics and philosophy; I got a PhD in the history and philosophy of
mathematics from Paris 1 Panthéon-Sorbonne, then did post-docs at McGill
University (Montreal) and at the CNRS (Archives Henri-Poincaré, Nancy). In Fall
2023, I was a visiting fellow at the Center for Philosophy of
Science of the university of Pittsburgh.
Research
Broadly speaking, I am interested in the way mathematics is expressed: the
notations or diagrams one uses, the definitions one chooses, the way one
structures papers or books, etc. Why do these matter? In particular, how are
these related to epistemic values like intelligibility, explanatoriness, and so
on? I approach these questions from a variety of angles, historical as well as
philosophical. On the historical side, I have studied 17th- and 18th-century
analysis as well as the history of mathematical logic in the 19th
century; I am currently working on 19th-century enumerative geometry and on
Nicolas Bourbaki’s books on topology.
