I am an Associate Professor in the Physics and Astronomy Department at the University of New Hampshire. My research focuses on numerical simulations in general relativity. I study merging compact objects (black holes and neutron stars), and model the gravitational wave and electromagnetic signals (gamma-ray bursts, optical/infrared transients) that they emit, as well as their role in the production of heavy atoms such as gold and platinum. I am also a member of the SxS Collaboration, the Network for Neutrinos, Nuclear Astrophysics, and Symmetries (N3AS), and the Nuclear Physics from Multi-Messenger Mergers collaboration.
In the past, I have also studied the evolution of accretion disks, both in the context of accretion onto supermassive black holes and for the formation of planetary systems.
I obtained engineering degrees from both the Free University of Brussels (ULB) and the Ecole Centrale Paris (ECP) in 2005, before moving to the United States for my PhD. I graduated from Cornell in 2011. I then worked for 3 years as a post-doctoral fellow at the Canadian Institute for Theoretical Astrophysics (CITA) in Toronto, and for 3 years as a NASA Einstein post-doctoral fellow at the Lawrence Berkeley National Lab (LBL).
