Short biography

I received the B.S. and M.S. degrees in physics engineering and the Ph.D. degree in engineering sciences from the École polytechnique de Bruxelles, Université libre de Bruxelles, in 2013 and 2018. From 2019 to 2020, I was a Postdoctoral Researcher in the Department of Applied Mathematics and Theoretical Physics, in the Centre for Mathematical Sciences of the University of Cambridge. I then worked as a Postdoctoral Researcher in the Department of Physics of the Technical University of Denmark, from 2021 to 2023. I am currently a Senior Postdoctoral Fellow of the F.R.S.-FNRS in QuIC. My research focuses on mathematical and information-theoretic aspects of quantum information theory, as well as quantum optics.
