I am an astrophysicist at the Laboratoire d'Astrophysique de Marseille (LAM).

I defended my PhD thesis, entitled "Optical Spectra of Thermonuclear Supernovae in the Local and Distant Universe", at the Ludwig-Maximilians Universität (Munich, Germany) in November 2005.

During my postdoc at the Harvard-Smithsonian Center for Astrophysics (CfA) I founded the CfA Supernova Archive, where you can freely download light curves and spectra of many supernovae.

You can view my CV here [pdf]

Supernova model results

The results from our numerical simulations on supernovae are available on Zenodo.

This research has benefited from funding by the Agence Nationale de la Recherche from 2011 to 2016, under grant number ANR-2011-Blanc-SIMI-5-6-007-01. See the project description here: RTCCSN.
