My research explores the evolutionary history of terrestrial vertebrates in Gondwana during the Triassic, a period of intense environmental transformation that followed one of the most profound biological crises in Earth’s history. I am interested in how vertebrate faunas adapted to changing ecological conditions and how these changes are reflected in patterns of diversity and morphology.

I work primarily on non-mammalian cynodonts and related synapsids from Argentina, using detailed anatomical study and phylogenetic approaches to investigate their evolutionary relationships and paleobiogeographic history. These fossils provide key evidence for understanding the early stages of mammalian evolution and the restructuring of terrestrial ecosystems.
