Postdoctoral Fellow @ Phylogenomics lab,   University of Vigo;



Departamento de Bioquímica, Genética e Inmunología, Universidad de Vigo, 36310 Vigo, Spain



I am broadly interested in phylogenetic inference and its use on understanding the processes that lead to genes, populations and species divergence. Most of my work has focused on colonization and diversification patterns of reptiles from Western Indian Ocean Islands (Madagascar, Comoros and the Seychelles).


Currently I am a postdoctoral fellow at the phylogenomics group at the University of Vigo, where I am collaborating in several projects related to phylogenetic and specie-tree inference from closely related genomes using next-generation sequencing (NGS) data, mostly using mollusks as model organisms.

Yet, I keep a feet when possible in Seychelles’ herps, in collaboration with AP members at CIBIO-UP.

Science divulgation & Media

Our local newspaper, Faro de Vigo, decided to give some coverage to my work: check it out here  :)

Here our “Giant Gecko” fieldwork getting some coverage in the Seychelles :) Paper is finally out, check bellow!


Check out this really cool project and book about evolution, where I collaborated. Freely available here - only portuguese and spanish, sorry!


I’ve collaborated with other divulgation and environmental education activities. We even made some cool guides small books. You may want to have a look here and here. Usually I was on the amphibians and reptiles group (the coolest!) :)
