Curriculum
Formations
Short bioValérie Chavez-Demoulin holds a Master degree in Mathematics of EPFL. Following her PhD in Mathematics at EPFL, she obtained a Marie Heim-Vöglin grant for a postdoctoral position in collaboration with the SLF in Davos. Afterwards she has been a research fellow at the Department of Mathematics at ETH, Zurich. Aside from her research, she has been the quantitative risk manager for a Hedge Fund for 3 years. She is member of the RiskLab, ETH, Zurich and is an elected member of ISI (the International Statistical Institute) and of the Bernoulli Society for Mathematical Statistics and Probability.
