    Chronology of our Galaxy from Gaia Color-Magnitude Diagram fitting (GhronoGal)
    The overarching goal of ChronoGal is to unveil the sequence of events and physical processes that have shaped the Milky Way (MW) from its early assembly to the present, by providing the holy grail of Galactic Archaeology (GA): precise age information. Our Galaxy is key to study disk galaxy formation and evolution, as it can be analyzed in

    Physical properties and evolution of Massive Stars
    This project aims at the searching, observation and analysis of massive stars in nearby galaxies to provide a solid empirical ground to understand their physical properties as a function of those key parameters that gobern their evolution (i.e. mass, spin, metallicity, mass loss, and binary interaction). Massive stars are central objects to

    Morphology and dynamics of the Milky Way
    This project consists of two parts, each differentiated but both complementary: morphology and dynamics. Detailed study of the morphology of the Milky Way pretends to provide a data base for the stellar distribution in the most remote and heavily obscured regions of our Galaxy, through the development of semiempirical models based on the

    Milky Way and Nearby Galaxies
    The overall aim of the project is to study the morphology, stellar populations, kinematics and dynamics (including formation and evolution) of the Milky Way and its satellite galaxies and other Local Group galaxies. The project can be divided into two main lines: I. Structure of the Milky Way and nearby galaxies. The detailed study of the

    Physics of Ionized Nebulae
    The research that is being carried out by the group can be condensed into two main lines: 1) Study of the structure, dynamics, physical conditions and chemical evolution of Galactic and extragalactic ionized nebulae through detailed analysis and modelization of their spectra. Investigation of chemical composition gradients along the disk of our

    Nucleosynthesis and molecular processes in the late stages of Stellar Evolution
    Low- to intermediate-mass (M < 8 solar masses, Ms) stars represent the majority of stars in the Cosmos. They finish their lives on the Asymptotic Giant Branch (AGB) - just before they form planetary nebulae (PNe) - where they experience complex nucleosynthetic and molecular processes. AGB stars are important contributors to the enrichment of the
