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 degraded waterbodies. A considerable part of my work involves collaboration with the water industry, government agencies and NGOs, and these collaborations provide a significant part of my research funding. 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.
