My activity

I am a zoologist specialized in the study of mammals, mainly small mammals such as rodents, bats, and marsupials. My studies have focused on the study of diversity, distribution, morphology and phylogenetic relationships. Currently I am a doctorate and I work in the Phylogeny, biogeography and ecological adaptation of rodents of the genus Thomasomys. This study addresses the following objectives: infer the phylogenetic relationships of the species of the Thomasomyini tribe by focusing on the genus Thomasomys, determine the divergence time of the main clades, determine the historical phylogeographic patterns and the speciation processes of the genus, identify the area of origin, direction and sequence of the colonization of the Andes, to quantify the role of the Andean orogeny in the diversification of Thomasomys, and to study the impact of environmental variables on the morphological adaptation of Thomasomys. For this, I will use morphological methods using microtomography and geometric morphometry, and molecular methods using mitogenomes and a set of nuclear genes.

Keywords :

Adaptation – Geometric morphometry – Phylogeny – Sigmodontinae – Speciation
