Research Interests

I am interested in the behaviour and ecology of insects and in particular in how natural selection has moulded the behaviour of individual insects to their own specific ecology. My main current research interests are in the ecology of insects from oil palm plantations in South East Asia and in the evolution of social behaviour in digger wasps.

I am part of the Insect Ecology group, run by Dr Edgar Turner. We are carrying out a collaborative project with the oil palm industry, the BEFTA Project, which experimentally manipulates the understory habitat complexity within plantations to test its effect on a wide range of taxa and ecosystem processes. The aim of this work is to establish management practices that can be employed to enhance both biodiversity and important ecosystem functions, such as pest control, in tropical agricultural landscapes.

My initial research was on the biology of saltmarsh and marine insects, but in more recent years I have become fascinated by the origins of social behaviour in insects, in particular in aphids, paper wasps, hover wasps, and the solitary sphecid wasps.
