Welcome to my personal Web page:
I am an Associate Professor at the department of Chemistry and Physics at Saint Mary's College, Notre Dame, Indiana
The contemplation of celestial things will make a man both speak and think more sublimely and magnificently when he descends to human affairs.

I am an observational astrophysicist. My research interests include the chemical composition of stars in open clusters and in the field, synthetic spectra, binary stars, HgMn stars and model atmospheres.
I got my PhD from Universite de Montpellier II in 2007. My thesis was entitled "Chemical abundances determination in A/F dwarfs members of open clusters. Constraints on the evolutionary models including transport processes".
I joined the Gaia team from December 2008 till September 2010 at the University of Barcelona (UB) where I worked on the calibration of the photometric instrument of the Gaia space telescope.
I am a member of the POLLUX team: Production of synthetic spectra and SEDs for B, A and F stars (GRAAL-LUPM department). I am a member of the GES (Gaia Eso Survey) WG 13. I am also a member or the WEAVE team responsible of the QA of A stars observations.
In Fall 2010, I joined the Department of Physics and Astronomy at Notre-Dame University-Louaize (NDU), Lebanon.
Since Fall. 2021, I joined the Department of Chemistry and Physics at Saint Mary's College, Notre Dame, Indiana.
