Biography

I am an observational astrophysicist. My research interests include the chemical composition of stars , synthetic spectra, binary stars, HgMn stars, model atmospheres, and numerical methods for astrophysics.
I got my PhD from Universite de Montpellier II in 2007.
I did a postdoc at the University of Barcelona (UB): calibration of the photometric instrument of the Gaia space telescope (2008-2010)
In Fall 2010, I joined the department of Physics and Astronomy at NDU university, Lebanon.
In Fall 2021, I joined the department of Chemistry and Physics at Saint Mary's College, Notre Dame, Indiana, USA.
