We are broadly interested in identifying mechanisms that generate ecological and evolutionary diversity in amphibians and reptiles. We address questions across multiple scales ranging from populations to species and higher-level systematics. We are incredibly fortunate to be based at the National Museum of Natural History where biological collections are central to our research.
Current Lab Projects
The evolution of visual systems during major life history transitions in frogs (in collaboration with Dr. Matt Fujita at the University of Texas Arlington, Dr. Jeff Streicher and Dr. David Gower at the Natural History Museum London, and an international team of frog vision experts and enthusiasts!) This new project aims to characterize spectral, genetic, and morphological diversification of the visual system in relation to major ecological transitions in frogs. We received an NSF-NERC award in January 2017 and will be looking for two postdocs (one based at NMNH in Washington D.C. and one based at the Natural History Museum in London) starting in mid-2018.
The genomics of hybridization in São Tomé reed frogs (in collaboration with Dr. Stefan Prost, Stanford University). An ongoing project in the lab aims to integrate genomic, behavioral, ecological and morphological studies to characterize the roles of natural and sexual selection in structuring gene flow in the Hyperolius thomensis – H. molleri hybrid zone on São Tomé Island. Data collection to sequence draft genomes for this ongoing project is generously funded by a Smithsonian Institution Scholarly Studies Award.
