Geoff Phillips is a freshwater ecologist who after research on submerged aquatic plants has spent over 40 years working as a research scientist and environmental manager for the Environment Agency. During this time he carried out research on the ecology of shallow lakes, ranging from investigating the mechanisms for release of phosphorus from sediments to the role of grazing by zooplankton and its application to whole lake biomanipulation. He has also led work to develop new biological methods for the Water Framework Directive and chaired the UK Freshwater task team that advised the UK environment agencies on the implementation of the Water Framework Directive. He has contributed to several large EU projects which contributed to the comparison and harmonisation of European freshwater assessment systems. He is particularly interested in eutrophication of lakes and rivers and the impact of restoration measures over long time periods.
