About Me

I obtained my Ph.D. in astrophysics in 2024 at the Universidade Federal do Rio Grande do Sul (UFRGS, Brazil), including a six-month split-site period at Stockholm University.

Currently, I am a postdoctoral researcher working at the Istituto Nazionale di Astrofisica (INAF), Osservatorio Astronomico di Padova, Italy.

My research focuses on extragalactic astronomy, with particular interest in galaxy formation and evolution, the physical and chemical properties and dynamics of ionized gas, and the role of dense environments in driving galaxy evolution and shaping their morphologies.
