I am an evolutionary biologist interested in molecular phylogenetics and systematics, molecular evolution, comparative analysis, phylogeography, and, more recently, transcriptomics and genomics. My main research line is focused on molecular phylogenetics and evolution of the major lineages of extant amphibians, and particularly of caecilians. My research interests also encompass the study of the molecular and evolutionary dynamics of the mitochondrial genome (comparative mitogenomics), as well as the phylogenetic experimental design and methodology to most efficiently reconstruct large-scale phylogenies. I have also investigated the origin and ancestry of extant amphibians, as well as the diversification, phylogeography and speciation of several groups of amphibians, fishes, reptiles, and, more recently, birds using mitochondrial, multilocus, and genomic data generated with high-throughput sequencing techniques. I also maintain another research line in comparative transcriptomics in caecilians that aims for gene discovery and evolutionary analysis of skin components.
