Histological description of paleopathologies
By looking into the past and studying how ancient organisms (eg. dinosaurs) reacted to diseases, we provide new histological data to medicine.

Evolution of the Respiratory System in dinosaurs and other archosaurs
Modern birds are some of the organisms with the best respiratory performance. Our objective with this research front is to track the evolution of the air sacs system back to the non-avian dinosaurs for a better understanding of the histological traces of these pulmonary organs in the fossilized skeleton.

Metabolism, ontogeny, and the evolution of gigantism in dinosaurs
Dinosaurs are a very diverse group of organisms with an elevated metabolic rate. This implies also in fast growth rates when compared to other archosaurs. In this research front, we investigate the histology of diverse groups in order to understand the evolution of gigantism.

Dinosaur faunal diversity during the transitional rupture between South America and Africa
The separation of these two big continents resulted in a noticeable dinosaur faunal substitution in Brazil, during the Cretaceous Period. In this research front, we apply all available technologies to describe fossilized dinosaur traces from the Northeastern Outback. We aim to bring novel paleoecological details in a big volume of data.
