​Principal Investigator -- Paúl M. Velazco, Ph.D.

My research interests revolve around reconstructing relationships among mammals, from the population to suprafamilial level, and using the resulting phylogenetic hypotheses to test and revise evolutionary and biogeographic patterns. Most of my current work focuses on the bat superfamily Noctilionoidea, one of the most ecologically diverse groups of mammals.
​
My approach combines morphological and molecular data and a wide array of techniques and analyses to answer questions relevant to the evolution of mammals, including but not restricted to scanning electronic microscopy, micro computed tomography, linear and geometric morphometrics, as well as divergence-time, historical biogeography, phylogenetic, population genetics, and ecological niche analyses.
