The course tutor will guide students through a series of key topics via reading materials, online activities, and discussion forums. The discussion forums will be the primary space where students are able to interact with one another and their tutor to discuss questions, solve problems and share ideas – just as they would expect to do in a face-to-face classroom setting.

"My online study experience was enjoyable and beneficial. I consider the presentation of the course material to be exemplary and I found the feedback and assistance from the course tutor to be positively helpful and constructive throughout."

Research interests

My research focuses on understanding and quantifying the ecology, hydrology and management of wetlands and freshwater habitats. I have particular interests in the ecological importance of microflow environments provided by aquatic plants in rivers and wetlands; water and nutrient cycling in wetlands; wetland vegetation dynamics; constructed wetlands; biogeography of aquatic plants; and the conservation of freshwaters.

I have carried out field survey work in a diversity of freshwater habitats in Tunisia, Australia, Antarctica, Guatemala and the UK. I am a research associate in the Water Research Group in the School of Geography & the Environment at Oxford, and I am always keen to discuss possible collaborations in interdisciplinary research in pure and applied freshwater processes/ecology.

Marley Fen Project: I am part of a team carrying out field research and monitoring into plant-water relationships at Marley Fen in Wytham Woods, Oxfordshire. The results of our research are being used directly in the management plan for this SSSI site.

Reduction of Algal Loading on Water Treatment Works: I co-supervise a research project investigating the ecological functions of a floating reed bed, Living-Filter, on Farmoor Reservoir, for water treatment. The DPhil is funded by Thames Water and involves an industrial collaboration between Aquatic Engineering, Thames Water and the Department for Engineering Science at Oxford University. The research involves field investigations at Farmoor Reservoir and lab experiments using bioreactors at Begbroke Science Park.
