Professional summary

Research Interests

Stephen is an ecophysiologist of aquatic algae and plants with a particular interest in relating changing environmental conditions, particularly those driven by climate change, to physiological and ecological responses through laboratory experiments, field measurements, use of novel techniques and the analysis of long-term environmental data. He has a particular interest in changing CO2 availability in water and the effects this has on ecology of algae and plants. He recently retired but is continuing as a UKCEH Fellow.
