Research

Insect Reproductive Physiology. My research interests lie within the field of insect reproductive physiology. In particular, I am interested in the means by which cells and tissues communicate with one another in order to produce integrated and coordinated output. To this end, I have developed a model system in which I have identified motor and modulatory input onto the oviducts of the locust, Locusta migratoria. These inputs must be coordinated in order to produce the correct response at the appropriate time (e.g. egglaying). This work entails neurophysiology, neurochemistry, receptor physiology and signal transduction. Work of this nature can furnish the means of controlling insect pests by development of new insecticides.
