VENI Fellow / Research Associate

Autobiography

I studied Geography at University College London and a PhD at Silwood Park (Imperial College). In 2011 I joined the EGI as a postdoctoral researcher with Joseph Tobias and Nathalie Seddon. Since 2014 I have been a Veni Research Fellow at the University of Groningen with Rampal Etienne, but remain a visiting researcher in the Department of Zoology, Oxford.

Research Activities

My research focusses on understanding the processes generating broad-scale patterns of species diversity, and in particular why species richness varies so dramatically across the surface of the Earth and between different organism groups. To do this I integrate data on species geographic distributions and molecular phylogenetic relationships. I am increasingly interested in understanding the consequences of environmental change on biodiversity and the functioning of ecosystems.
