I am an astrophysicist at the Laboratoire d'Astrophysique de Marseille (LAM). My research mainly revolves around the analysis of radiation from exploding stars known as supernovae. At LAM I lead the Transients discussion group.

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]

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.
