A number of students have completed their degrees in the last two years, so we are looking for new students. If you are interested in the lab, see the page on Prospectives.


  • Mariana Vasconcellos is in her final year of her PhD. She is studying evolution and diversification of Hypsiboas treefrogs in the Brazilian Cerrado using historical biogeography, phylogeography, species distribution models, and taxonomy.
