I am a biologist interested in biodiversity, biogeography, phylogenetics and conservation of amphibians and reptiles. My research integrates a broad range of techniques, including fieldwork, taxonomy, and molecular systematics to interpret patterns of speciation and diversity. I am particularly interested in the phylogenetic diversification of African amphibians and use of molecular tools to define species boundaries. I am currently investigating two widespread frog families, puddle frogs (Phrynobatrachidae) and grass or rocket frogs (Ptychadenidae), to understand the complex diversification patterns of these lineages across sub-Saharan Africa.

In addition to my research, I am the creator and administrator of the African Amphibian Lifedesk, a community-driven resource for information on African amphibians.
