    Studying galaxies at low and high redshifts with GRBs
    Long gamma-ray bursts are supposed to be connected to the death of very massive stars. Due to their brightness, we can detect them to much larger distances than...

    Studying the Halo via Its NEarby low-mass Dwarfs
    Studying the Halo via Its NEarby low-mass Dwarfs (SHINED) is an ongoing project aiming to understand the Galactic halo with metal-deficient low-mass stars (LMS)...

    Supergiant Stars as Extragalactic Probes of Cosmic Abundances and Distances
    The determination of chemical composition and distances of galaxies is crucial for constraining the theory of galaxy formation and evolution in a dark energy...

    Supergiants with an Interesting Past
    Exciting things may have happened sometimes to the stars we see in the sky today. For example, Betelgeuse, also known as Alpha-Ori, an M-type red supergiant...

    Testing stellar evolutionary models from detached eclipsing binary stars
    We employ a Bayesian method to infer stellar parameters from the PARSEC v1.2S library of stellar evolution models and test the accuracy of these theoretical...

    Testing stellar evolutionary theory with asteroseismology and/in binary stars
    The theory of stellar evolution is well developed over the past decades, and in particular the predictions of one dimensional numerical models have passed basic...

    The binary population in Galactic globular clusters: theory versus observations
    I present the first results of a long term project devoted to the study of the evolution of the binary population in globular clusters. Using deep ACS@HST...

    The Bowen Survey; detecting donor star signatures in low mass X-ray binaries
    For most persistent low mass X-ray binaries (LMXBs) and transients in outbursts the optical emission is dominated by reprocessing of the X-rays in the outer...

    The chemical composition of the Orion star forming region: stars, gas, and dust
    The Orion star forming region is an ideal laboratory for many astrophysical studies. In this talk I will present a study of the chemical composition of early B...
