Research activities

My research activity is focused on the study of galaxy formation and evolution from the characterization of resolved stellar populations. For this task I developed a state-of-the-art code (SFERA; Star Formation Evolution Recovery Algorithm) able to recover the star formation history of any galaxy from its Color-Magnitude Diagram. My playground is our Galaxy, the Magellanic Clouds, and many dwarf galaxies in the Local Volume. For my research I’m an avid user of the Hubble Space Telescope (HST) and ground-based facilities such as the VLT Survey Telescope (VST) and the Large Binocular Telescope (LBT). Indeed, I’m an active Co-I of several galactic surveys, like the HST “Legacy ExtraGalactic UV Survey” (LEGUS), the “Hubble Tarantula Treasury Project” (HTTP), the LBT “Smallest Scale of Hierarchy Survey” (SSH), and the VST program STEP. Most recently, I’m working with the James Webb Space Telescope (JWST) to dissect images of a sample of nearby star forming galaxies into millions of stars.
