Marwan Gebran is an observational astrophysicist. His research interests include the chemical composition of stars in open clusters and in the field, binary stars, HgMn stars and model atmospheres. He is also an active member of the POLLUX team (database for high resolution synthetic spectra and spectral energy distributions). Marwan joined the Gaia team from December 2008 till September 2010 at the University of Barcelona (UB). He worked on the calibration of the photometric instrument of the Gaia space telescope.
