A Little About Me
A French cosmologist in South Korea
My research interests focus on falsifying different aspects of the concordance LCDM model using N-body simulations and advanced statistical methods. I am also a member of the DESI collaboration, involved in the time domain and the cosmological simulations working groups.
I completed my PhD at LERMA , Paris Observatory and Université Pierre et Marie Curie, working in the Galaxies and Cosmology group with Françoise Combes and Benoit Semelin, and a member of the Momentum project. I was also a Teaching Assistant at the Université Paris Diderot, where I taught Physics and data analysis.
After that, I moved to South Korea, a growing hub for research, in particular in Astronomy and Cosmology, and I became a Research Fellow in the Astrophysics and Cosmology group of the Korea Institute for Advanced Study (KIAS) in Seoul with Profs. Changbom Park and Juhan Kim on cosmological structure formation, from galaxies to the large-scale structures of the Universe, using numerical simulations such as the Horizon Run 4 simulation. I then moved to the CosKASI group at the Korea Astronomy and Space Science Institute in Daejeon where I was working with Arman Shafieloo.
