I am a postdoctoral fellow at the Max Planck Institute for Astrophysics and from March 2021 an Associate Professor at the Institute of Physics of University of Sao Paulo. I study several topics in early universe cosmology, including the initial singularity, the early evolution of the universe and reheating. I am also interested in the late expansion of the universe, studying the phenomenology of dark energy. Testing those models using the current observational probes and new observational windows are also part of my research.
