I am a postdoc at the Institut de Mathématiques de Bordeaux (IMB), University of Bordeaux, currently working on the identifiability of the state-space models. In an ecological context, I study the dynamics of the abundance of animal and/or plant species over time.

I obtained my PhD from the Institut Montpellierain Alexander Grothendieck (IMAG) at the University of Montpellier. I was working on dimension reduction (PLS-type) models and on the interactions between species through factor and mixture models. I followed this position by two years as a teaching fellow in mathematics, in Montpellier as well.
