Professor James Cook (Theme Leader - Plants Animals and Interactions)

Professor James Cook is leader of the Plants, Animals and Interactions research theme.

His research interests lie in the ecology and evolution of species interactions, and he is particularly interested in how intimate symbiosis influences the biology of the species involved.

Pollinators are a special interest and his current research focuses mainly on insect pollinator communities and their role in pollination of horticultural crops. He is also an expert on specialist pollination systems, such as the classic mutualism between fig trees and wasps, while another research priority centres on insects and their endosymbiotic bacteria.

James is currently leading three projects to better understand the role of insects in pollination of Australian horticultural crops, and develop resilient pollination options in the face of threats to honeybee populations. These projects cover research on crop pollination, stingless bee biology and husbandry, seasonal floral resource use by bees, bee health and diseases, and managed pollination with flies.

His research involves field, laboratory and glasshouse approaches and makes extensive use of molecular methods. His research involves links with collaborators in Australia, India, China, France, UK and USA. James also has wider research interests in animal behaviour, conservation biology and evolutionary genetics.

James has a BA (Zoology) from Oxford University and PhD (Evolutionary Biology) from Imperial College London. His previous academic posts have been at La Trobe University, Imperial College London, and the University of Reading.
