The focus of my career research has been the ecology and physiology of aquatic algae, terrestrial algae and the use of algae as indicators of environmental change. Research topics I have investigated include: ecological studies of phytoplankton and periphyton (Devils Lake, Fox Lake, Kellys Slough, USA; Welsh coast, Pembroke, Wales, Kindrogan, Scotland); terrestrial studies: soil algae (prairie, desert and forest ecosystems, open cast mining and metal contaminated soils); and laboratory studies (heavy metal uptake, stress proteins, phenotypic plasticity, development)
My recent research has focussed on gene regulation in Desmodesmus, as a model to understand the origin of multicellularity, predator-prey relationships between Daphnia and Desmodesmus, taxonomy of Desmodesmus using a polyphasic approach.
