About me

I'm a postdoc researcher working at CEA (France) in collaboration with David Elbaz on the Star Formation History of Galaxies.

During my PhD at the Laboratoire d'Astrophysique de Marseille (France), I studied the dust properties of the local galaxies of the Herschel Reference Survey (PI: S. Eales, Boselli et al. 2010), a sample designed to be representative of the local universe, under the supervision of Alessandro Boselli. I acquired an extensive expertise in Herschel data and in the analysis and modeling of the infrared SED of galaxies.

From studying the local universe and normal star forming galaxies, I extended my research interest to the UV-to-radio emission of high redshift galaxies and Actve Galactic Nuclei in collaboration with Vassilis Charmandaris at the University of Crete (Greece).

I am now at CEA working on extragalactic deep surveys as part of the ASTRODEEP PF7 to study the star formation history of galaxies. From January, 1st, I will be at LAM (Marseille, France) starting a CNES fellowship on the study of Gamma Ray Burst host galaxies and the telescope SVOM.
