Research Interests

My research focuses on the study of the stellar populations and physics/chemistry of the emission line gas of Active Galaxies, from optical up to mid-infrared data, in order to understand their inpact in the evolution of galaxies. The instrumentation used in these studies goes from optical (e.g., GMOS-LS, GMOS-IFU, SDSS-IV MaNGA, SIFS), near-infrared (e.g. SpeX, GNIRS, ARCOIRIS, NIFS, SINFONI) long-slit and integral field units (IFUs) to mid-infrared (Spitzer/MICHELE/T-ReCS) data. These instruments are attached on the GEMINI 8m telescopes, 4.1m SOAR telescope and on Nasa Infrared Telescope Facility (IRTF) 3m telescope. You can find my publication list here

Currently, my main research interests are the following:

⭐ Investigate the stellar kinematics and stellar populations of active galaxies, from optical and near-infrared data.

⭐ Study the excitation mechanisms of coronal lines in AGNs and normal galaxies.

⭐ Investigate the AGN in the context of galaxy evolution (feeding and feedback processes).

⭐ Analyze the physical properties of circumnuclear star forming regions in active galaxies and the AGN/Starburst connection.

⭐ Access the excitation mechanisms of the Narrow Line Region (NLR) emitting gas, in particular for the molecular hydrogen and [Fe II] emission in the near-infrared bands.

⭐ Investigate the near-infrared nuclear continuum from active galaxies using adaptive optics high spatial resolution spectroscopy.

⭐ Study the excitation mechanisms of the Narrow Line Region (NLR) emitting gas, in particular for the molecular hydrogen and [Fe II] emission in the near-IR bands.

⭐ I am a member of the SDSS-IV collaboration thought the LIneA Brazilian Participation Group

⭐ I'm part of the project: Gemini NIFS survey of feeding and feedback processes in nearby active galaxies
