I am a postdoctoral researcher at the IT University of Copenhagen, where I mainly work with Jes Frellsen.

I received in 2017 my Ph.D. in applied mathematics from Université Paris Descartes. I worked at the MAP5 lab, where I had the chance to be advised by Charles Bouveyron and Pierre Latouche.

My field of research is statistical machine learning, with a particular emphasis on model uncertainty and sparsity. During my Ph.D., I mainly developed new Bayesian model selection methods for high-dimensional data. I also currently work on deep generative models and their applications.
