LATEST NEWS - PhD studentship available!!!

APPLICATIONS OPEN for NERC-funded PhD studentship: Statistical modelling of how soil biodiversity and ecosystem function respond to human impacts in UK ecosystems. This project will be linked with the ongoing NERC-funded PREDICTS project and will be based in my group at the Natural History Museum in London. Deadline is 20th January 2014. Follow this link to find out more and to apply.



My group and I moved to the Natural History Museum in London in Autumn 2013, though I retain a part-time position at Silwood Park.


Research Interests

My group use primarily comparative approaches to study a wide range of fundamental questions in biodiversity science, using a range of taxa. Current projects include:

Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (PREDICTS): In collaboration with UNEP-WCMC, UCL, the University of Sussex and Microsoft Research, we are aiming to build a global model of how local biodiversity responds to human impacts.

Changes in distribution of British biodiversity: Together with the Biological Records Centre in the NERC Centre for Ecology & Hydrology, we are analysing changes in the distribution of the British flora and fauna to understand the driving forces and to improve the toolkit for making projections about the future.

Descent into the Icehouse: Macroperforate planktonic foraminifera have probably the best fossil record of any group.  What happened to them as the climate cooled through the Eocene towards the transition from "greenhouse" to "icehouse" worlds at the Eocene-Oligocene boundary? This work is part of a broader NERC-funded consortium.

Passerine bird evolution and biogeography: The Indo-Pacific region is the largest concentration of islands on Earth, and the core Corvoidea (crows and their relatives) are one of the largest evolutionary radiations in the region. This EU-funded project will combine a range of comparative approaches to test general hypotheses about evolution, biogeography and diversification.
