About Me

I obtained my B.Sc. (2018), M.Sc. (2020), and Ph.D. (2024) in astrophysics at the Universidade Federal do Rio Grande do Sul (UFRGS, Brazil). During my Ph.D., I carried out a doctoral research stay at Stockholm University (Sweden) through the PRINT-CAPES program.

From 2024 to 2026, I was a postdoctoral researcher at the Istituto Nazionale di Astrofisica (INAF), Osservatorio Astronomico di Padova, Italy. Currently, I am a Fellow at the European Southern Observatory (ESO) in Garching, Germany.

My research focuses on extragalactic astronomy, particularly galaxy formation and evolution. My interests include the physical, chemical, and kinematic properties of ionized gas, as well as the impact of dense environments on galaxy evolution and morphological transformation.
