My research encompass studies of Active Galaxies with an emphasis on the connection between the AGN and star formation at mid- and far-infrared wavelengths by using the Spitzer space telescope and Herschel space observatory. Recently, I has been involve on the study of massive molecular outflows as evidence of feedback processes between the central QSO and surrounding starburst on Ultraluminous Infrared Galaxies (ULIRGs)
