The main focus of my research is on the impacts and interactions of multiple anthropogenic global change phenomena and tropical forests. I am interested in better understanding how humans are impacting on the 'Earth System', specifically the tropical forest biome.

I have recently been developing an interest in African tropical forests, as over recent decades both data and theory about tropical forests generally (e.g. maintenance of diversity) have been heavily based on information from Latin American forest. However, approximately one quarter of the worlds tropical forest is in Africa, and they may differ substantially different from Latin American forests.
