My research has aimed to address one of the fundamental questions of tropical biology – how and when did the huge species numbers in the tropics arise? It is grounded in fundamental, descriptive taxonomic, inventory and phylogenetic research, which provides the foundation to address evolutionary and biogeographic questions.

I am Head of the Tropical Diversity section at RBGE (http://www.rbge.org.uk/science/tropical-diversity), which currently comprises c. 35 people including researchers, PhD students, RBGE associate scientists and nine core-funded scientific staff. I am a Visiting Professor at the School of Biological Sciences, University of Edinburgh. I have served on the Natural Environment Research Council, Peer Review College (2008-2011) and the Biology Panel of the Danish Agency for Science, Technology and Innovation (2012 - 2015). I teach Phylogenetics, Plant Geography and Systematics to MSc and undergraduate students at the University of Edinburgh.
