ABOUT ME
Since September 2021, I am an Associate Professor (Maître de Conférences) at the Catholic Institute of Advanced Studies (ICES - Institut Catholique de Vendée).
​
​
Previously, I was a Temporary Research and Teaching Attaché at the University of Montpellier - IMAG lab (Institut Montpelliérain Alexander Grothendieck), where I obtained my PhD in Statistics on 19 April 2019. My PhD thesis entitled Introducing complex dependency structures into supervised component-based models was done under the supervision of Catherine Trottier and Xavier Bry. It mainly deals with regularization methods for multivariate generalized linear mixed models.
​
​
Between September 2019 and August 2021, I was a postdoctoral researcher at the INSERM center "Bordeaux Population Health" (Biostatistics team). Under the supervision of Virginie Rondeau, I worked on a generalization of joint models (mainly for recurrent events and a terminal event) that tries to get away from the usual assumption of proportional hazards.
