If you are looking for a Ph.D. at the interaction between Economics and Mathematics, several opportunities are open.
– If you are more interested in the mathematical side of Game Theory, I recommend you’d consider applying to the Ph.D. programme at the London School of Economics. You can find some information here.
– If you are more interested in the Economics side, your Ph.D. could be hosted by the CREST, joint research center between CNRS, Ecole polytechnique and ENSAE. You could either join after completing a Masters degree, or go through the Master in Economics first.
In both cases, funding opportunities are available.
If this sparks your interest, please have a look first at my research and papers. Then don’t hesitate to contact me along with your CV, a transcript of grades, and a research statement if you already have one.
