I have a bachelor's degree (2001) and a master's degree (2002) in Physics from the University of Brasilia, a master's degree (2004) and a Ph.D. (2008) in Physics from the University of Chicago. I was a postdoctoral researcher at the University of Pennsylvania (2008-2010) and at the University of Sao Paulo (2010-2011). I am currently a Professor at the Physics Institute of the University of Sao Paulo, an affiliated member of the Brazilian Academy of Sciences, a member of the Laboratorio Interinstitucional de e-Astronomia (LIneA) and a member of the Dark Energy Survey (DES) and Sloan Digital Sky (SDSS) collaborations. I work on Astrophysics and Cosmology, with focus on Galaxy Clusters, Large-Scale Structure, Photometric Redshifts, Gravitational Lensing, Statistical Methods, Modified Gravity, N-body Simulations.

Large scientic collaborations have been formed in search for explanations to questions still unanswered by the standard models of Physics and Cosmology. In particular, the Sloan Digital Sky Survey-IV (SDSS-IV) and the Dark Energy Survey (DES) have measured optical data (spectroscopic and photometric) of galaxies, with the goal of investigating one of the main challenges of modern cosmolog…
The main challenge of modern cosmology is comprehending the causes and consequences of the accelerated expansion of the Universe. Large international collaborations have brought together experts from various backgrounds in the search for explanations still not found in the standard model. The Dark Energy Survey (DES) is an experiment that will investigate cosmic acceleration using a serie…
In this project we will study the detection and use of cosmological voids, i.e. large empty spaces of low density in the universe. The Main focus will be the study, implementation and improvement of specific detectors, especially those who work in real galaxies catalogs.In addition, we will study their properties, e.g. abundance and profiles, and how they can be used to constraint cosmolo…
In this project we will study the 3 point correlation function of the density contrast field and its Fourier transform: the bispectrum. The bispectrum importance is due to the non-gaussianities. Non-gaussianities arise in the density field evolution, but they are also associated with inflation models. The 3PCF calculus has additional information if compared to the 2PCF. For its calculus, …
We are interested in testing alternative gravitational theories, modified on cosmological scales.We will analyze n-body cosmological simulations in order to obtain complementary observables such as dark matter halo and void abundances as a function of its mass and red-shift.We will use this complementary observables, in particular the void abundance, in order to constrain the cosmological…
Whole-sky surveys are revolutionizing the way research is conducted in cosmology. In order to extract the maximum scientific output, standard methods used in the analyses need to be refined so systematic errors are not included. The Dark Energy Survey will map the sky in the optical bandwidth and will detect 200 million galaxies and 100 thousand galaxy clusters, aiming at providing a bett…

The next generation of galaxy surveys will probe the Large Scale Structure (LSS) of the universe with high precision and in large volumes. To constrain cosmology, the correct computation of the covariance matrices will be crucial. These computations can be made from theory, observational data or a large set of simulations. For theoretical computations, the limitation is that we do not kno…
Nowadays N-body cosmological simulations make up the strongest tool to look into the non-linear processes of halo formation and distribution in cosmology. Those overdose structures can be connected to the outcomes of optical surveys through the mass-richness relation. N-body simulations are also the hardcore for building the cluster-galaxy catalogs that are utilized to validate the method…
The next generation of cosmological surveys will probe the Large Scale Structure of the universe with high precision. For constraining cosmology, it is crucial to improve the calculation of the theoretical matter power spectrum and bispectrum at non-linear scales. Standard Perturbation Theory (SPT) uses a series expansion in the matter field to solve the Navier-Stokes equations order by o…
