I have been working trying to integrate genetics and stable isotopes in samples from both plant and animal collections to test levels of assignment accuracy that might exceeds those of either method alone.

The main idea of my research is the use of stable isotopes as a tool to combat animal trafficking. More specifically, the intent is to characterize the isotopic fractionation and signature shift of wild versus captivity Saffron Finch (Sicalis flaveola). This is the most trafficked animal in Brazil, and stable isotopes can be a powerful methodology to identify "laundry" individuals and the origin of wild animals seized.

My research focuses on the use of stable isotopes as a tool to discriminate captive x wildlife animals as well as to identify the geographic origin of seized animals from the Brazilian Amazon region.

My master's dissertation focuses on the relationship between soil biota and magnetic susceptibility in a fertilization experiment in the Cerrado

I'm using C and N stable isotopes in Saffron Finch tissues (Sicalis flaveola) to identifying diet seasonality as well as it can be associated with pigments that gives plumage color. I'm also developing spatial models for C, N, O and H based on Saffron Finch feathers for the Cerrado region.

I'm using stable isotope (SIA) and X-ray fluorescence (XRF) analysis to determining commercial fish production systems and geographic origin trying to identify environmental violations involving the capture and trade of fish from illegal operations.

My master's research seeks to assess the potential of using stable isotopes and inorganic elements to trace the geographic origin of Amazonian wood. The improvement of these methods will enable the development of a useful tool for the production of expert evidence to be presented in court.

The central idea of my research is to study the implications of pedological variables on the spatial distribution of nitrogen and carbon and on the dynamics of organic matter in soil, exploring how this may express the landscape in a Cerrado area.
