Post-doctoral Fellow at the Pontificia Universidad Católica de Chile - Santiago, Chile
Hi there!
I am a researcher with a background in astrophysics and a passion for exploring the evolution of galaxies. I am currently a postdoctoral fellow at the Pontificia Universidad Católica de Chile in Santiago, Chile. I study galaxy evolution, resolved and unresolved stellar populations, galactic archaeology, and astrostatistics.
I was born and raised in Brasília, the capital of Brazil, located in the Federal District. Brasília was designed in the 1950s to serve as the nation's capital and was officially inaugurated in 1960. Today, it is recognised as a UNESCO World Heritage site.
My passion for astronomy began during my school years, sparked by reading the works of Carl Sagan. I devoured many of his books, including The Demon-Haunted World, Billions & Billions, and Contact, among others. It was only much later that I had the opportunity to watch the Cosmos TV series.
In 2007, I moved to São Paulo, where I lived for 14 years while pursuing a Bachelor's degree in Physics at the University of São Paulo, graduating in 2011. After a brief period working in the private sector, I completed a Master’s degree between 2013 and 2015, during which I investigated the potential link between the optical and ultraviolet emissions from galaxies.
Between 2015 and 2020, I completed my doctoral studies at the Institute of Astronomy, Geophysics, and Atmospheric Sciences at the University of São Paulo, focusing on the ultraviolet upturn in galaxies. As part of my research, I spent six months on secondment at the Autonomous University of Madrid in Spain (2018-2019). My work, which utilised a Bayesian logistic model, was the first to demonstrate an excess of galaxies exhibiting this phenomenon at a redshift of approximately 0.25. Additionally, I showed that galaxies with strong UV emissions tend to be more massive, older, and metal-rich compared to their weak UV-emitting counterparts.
From March 2021 to September 2023, I served as a post-doctoral researcher at the Nicolaus Copernicus Astronomical Center in Warsaw, Poland, where I specialised in Galactic Archaeology. Following this, I briefly joined the Computational Cosmology Group at the Center for Theoretical Physics, also in Warsaw, for a short post-doctoral stint from October 2023 to March 2024. Since April 2024, I have been a post-doctoral fellow under the Fondecyt scheme at the Pontifical Catholic University of Chile, where I joined the EvolGal4D Group led by Prof. Patricia Tissera.
My primary research interests include galaxy evolution, both resolved and unresolved stellar populations, galactic archaeology, and astrostatistics. While these areas form the core of my work, my curiosity spans the broader field of astrophysics. I actively participate in several collaborations, including the Cosmostatistics Initiative (COIN) and the Gaia-ESO Survey, the latter of which has now successfully concluded.
