Welcome to my website. I am a National Geographic Explorer and recently recieved my PhD from the Department of Ecology and Evolutionary Biology at the University of California, Santa Cruz. I study the diversity and distribution of fishes in Central Africa and use this information to promote freshwater conservation in the region.

I study African freshwater ecology, ichthyology and conservation. I am fascinated by diversity and the processes that drive species division and maintain this diversity. I am broadly interested in morphological and ecological diversity, and the exceptional rates of diversification seen in adaptive radiations, including the cichlids of Lake Bermin.

As a scientist and concerned citizen, I also have the obligation to advocate effective management and sustainable conservation through my work.
