About me

I currently hold the Joint Sophie and Tycho Brahe Post-Doctoral Fellowship between Hong Kong University (China) and the University of Copenhagen (Denmark). I live in Hong Kong since 2021, but I was in Copenhagen prior to that.

I study supermassive black holes which are found in the center of galaxies since the youth of the Universe. In particular, I estimate how frequently black holes merge, and how frequently they devour stars. To this purpose, I use theoretical analytical models, numerical simulations, and more recently, machine learning.

I obtained my PhD. at the Institut d'Astrophysique de Paris (France), and my BSc at the Ecole Normale Supérieure de Cachan (France).

I have been tutoring students since more than 10 years (some are now doing a PhD.!), I was awarded the Agrégation de Physique in 2015, and I have taught at undergraduate level since my PhD.

I am french and I spent most of my life in Paris, but I love being abroad to meet new people, to discover new cultures, and to try new food...!
