EVOLUTIONARY MEDICINE
evo_csMy most recent project explores whether our evolutionary history predisposes us to craniosynostosis and what evolution can teach us about this disease. Craniosynostosis is a birth condition where one or more of the sutures that separate the cranial bones close prematurely, which may cause head malformations and brain damage. Though a disease in humans, craniosynostosis shares many features with the normal evolution of the head. My goal is to understand how similar is suture closure in evolution and in craniosynostosis. This research has the potential to translate into novel, complementary tools to diagnose and treat craniosynostosis, while giving us a new perspective on the evolution of our own body.

ANATOMICAL NETWORK ANALYSIS (AnNA)
g5852I am always working toward a better implementation of Network Theory to study the evolution and development of anatomy and morphology: improving the morphological interpretation of concepts from network sciences and testing new methods of analysis.

EVOLUTION OF TETRAPODS
fin_limb_1Macroevolutionary studies benefit from the level of abstraction offered by AnNA and there are still many possibilities of study in this context. I am particularly interested in the study of the evolution of morphological complexity and modularity in the skull of vertebrates, and how it is related to the evolutionary trend toward skull with fewer number of bones (Williston’s Law). At the same time, I am also interested in the evolution of the tetrapod limbs during the fin-to-limb transition in the Devonian Period. Specifically, how the morphological modularity of the limb has changed in its way from water to land.

GENERAL EVOLUTIONARY THEORY
modularity_skullMy research in this topic on the study of macroevolutionary patterns in morphology; in particular, in explaining and quantifying directional patterns of evolution and the evolution of modularity.
