The different math finance research groups in Paris (from Ecole Polytechnique, Université Paris Dauphine, CREST, Universite de Paris VI- VII, Université d'Evry, and Université de Marne La Vallée) jointly organize a series of seminars at the Institute Henry Poincare, at the heart of the Latin Quarter.
For visitors like me, it is a wonderful opportunity to meet students and researchers from all over Paris under the same roof.
Once a year, they dedicate an entire day to talks by PhD students, in many cases giving them the first chance to present their work in front of a friendly but rigorous audience.
I spent the day yesterday attending one of these journee des doctorants and was immensely impressed by the quality of the talks and the results presented. It also forced me to step up my french.
