My research focuses on the evolutionary history of lizards and amphisbaenians as revealed from the fossil record. Phylogeny, taxonomy, paleobiogeography and paleocology are some of the approaches used in my works, which usually include the description and identification of new specimens and the erection of new fossil taxa. Applied methodologies include phylogenetic analyses using parsimony and CT scanning of key specimens. I have also recently started studying macroevolutionary patterns in squamate reptiles using analyses of evolutionary rates and disparity through time as informed from discrete character morphological matrices.

Besides this, my interests concerns other vertebrates such as Mesozoic and Cenozoic amphibians or snakes, and Permo-Triassic vertebrate assemblages.
