Pierre Clairambault's page

Researcher at the CNRS, member of the Plume team in the LIP laboratory, in the ENS de Lyon.

I did my PhD thesis in the PPS laboratory in Paris, under the supervision of Russ Harmer and Pierre-Louis Curien. After that, I did a postdoc in the Department of Computer Science of the University of Bath with Jim Laird, then a postdoc in the Computer Laboratory of the University of Cambridge, with Glynn Winskel.
