GABRIEL S. FERREIRA
Comparative Biologist | Vertebrate Palaeontologist
I am a comparative biologist and vertebrate palaeontologist interested in the macroevolution of reptiles. I am currently working as a postdoctoral researcher and lecturer at the University of Sao Paulo at Ribeirao Preto, Brazil, with Prof. Dr. Max C. Langer's Lab.
My research focuses on the use of computational tools, especially micro-computed tomography, to explore macroevolutionary patterns and morphology of reptiles. Most of my track record was built on turtles, a group with a long evolutionary history (>210 million years), a considerable extant diversity, and a highly modified body plan, characteristics that make them a very interesting group for macroevolutionary studies.
I have recently received a double-degree Ph.D. from the University of Sao Paulo and the Eberhard Karls Universität Tübingen, Germany, under the co-supervision of Profs. Max Langer and Madelaine Böhme. My thesis, entitled "Patterns of Morphological Evolution in the Skull of Turtles: Contributions from Digital Palaeontology, Neuroanatomy, and Biomechanics" has been awarded the Bernhard-Rensch Prize 2020 by the Gesellschaft für Biologische Systematik, from Germany.
VIRTUAL MORPHOLOGY & PALAEONTOLOGY
Using micro-computed tomography, contrast-enhanced staining, and other digitalization techniques, I can virtually reconstruct the hard and soft-tissues in extant and extinct species. With the 3d virtual models a number of new questions and possibilities emerge, such as exploring the biomechanics of biological structures using Finite Element Analyses (FEA).
MACROEVOLUTION & PHYLOGENETIC COMPARATIVE ANALYSES
In order to understand evolution in the deep time I apply analytical techniques, such as geometric morphometrics, phylogenetic comparative analyses, and ancestral area reconstructions, to explore morphological disparity, species diversity, and biogeographical patterns in organisms.
SYSTEMATICS & TAXONOMY
The bases to explore evolutionary patterns are relationship trees. For that reason, part of my work is to describe new species and to construct phylogenetic hypotheses, using different time-calibrating methods, that can be employed in other analyses of reptiles.
