Research Interests
My work focuses on applied freshwater ecology, with a particular emphasis on bivalve molluscs. My particular interests are the conservation of rare species and threatened ecosystems, the biology and control of invasive species, and the use of biological processes to develop sustainable remediation and monitoring programmes for polluted waterbodies. A considerable part of my work involves collaboration with the water industry, the Environment Agency and NGOs, and these collaborations provide a significant part of my research funding. The interdisciplinary nature of my work is reflected in my joint membership of the Zoology and Chemical Engineering Departments. While the end-points of my work often have important applications, my research is driven by an enthusiasm for addressing fundamental questions in pure biology and ecology.
I currently have two projects funded by the World Bank running in China. One project involves the development of sustainable bioremediation methods for some of China’s most polluted lakes, the other is documenting the endemic biodiversity of the plateau lakes in southwest China. I am director and co-founder of BioBullets Ltd., a company that has developed a novel and environmentally-friendly way of controlling some of the world’s biggest aquatic pests. I currently have projects running in Europe and N. America for the control of zebra mussels, Brazil for the control of golden mussels, and in Colombia for the control of mussel fouling in shrimp farms. I also have projects looking at the biology and control of biofouling in the UK water industry, and am developing improved river management strategies for UK rivers in collaboration with the Environment Agency.
