About Me

I’m a Ph.D. researcher at the Institute of Astronomy and Planetary Sciences, University of Atacama, Chile. My research focuses on variable stars as tracers of Galactic structure and the chemodynamics of the Milky Way, using photometric (S-PLUS, GAIA) and spectroscopic (APOGEE, GALAH, LAMOST) surveys. Expertise includes applying data science techniques to astronomy, with demonstrated experience in large-scale data analysis, machine learning, and workflow automation. Proficient in building scalable data pipelines and employing astrostatistics to explore complex astrophysical phenomena, with a strong interest in leveraging data-driven approaches for both scientific discovery and broader real-world applications.
