Biography

Postdoc at the Jet Propulsion Laboratory / NASA

Education

  • PhD, Cosmology, IFT-Unesp / ICTP-SAIFR, Brazil (2024)
  • M.S, Astrophysics, Federal University of Rio Grande do Sul, Brazil (2020)
  • B.S. Physics, Federal University of Minas Gerais, Brazil (2018)

Professional Experience

  • Visiting scholar at Stony Brook University, New York, U.S. (2023-24).
  • Tutor of the minicourse: “The Accelerated Expansion of the Universe and the Cosmological Parameters” at IFT-Unesp, (2023).
  • Member of the organizer committee of the 44th edition of the “Paulo Leal Ferreira Congress” at IFT-Unesp (2021).

Community Service

I was a Physics teacher volunteer in 2022 for six months at “Psico”, a non-profit college-prep school located at the University of Sao Paulo, intended for low-income students who wanted to do the High School National Exam (ENEM).

Research Interests

Research interests rely on investigating dark energy models for the accelerated expansion of the universe, dark matter, and possible interactions between dark energy and dark matter. Use Roman to probe dark energy with systematics and non-linear scales. End-to-end weak lensing infrastructure and pipeline development. Type Ia supernovae, baryon acoustic oscillation, cosmic microwave background, weak lensing, large-scale structure, and combinations among these datasets to investigate extension beyond the standard cosmological model. Observational cosmology, modified gravity, and effective theories of large-scale structure.

Selected Awards

  • Book Access Scholarship Bernardo Alvares, Federal University of Minas Gerais (2016).
  • 2nd place on Brazilian Olympiad of Astronomy and Astronautics IOBFOG - Category 3, Brazilian Astronomical Society and Brazilian Agency (2007).
