Research Activities 30 years research experience in aquatic and wetland plant ecology and management, and the creation of wetlands for wastewater and drainage treatment and environmental enhancement.  Leads national research programs on ecotechnologies for treatment of sewage and agricultural diffuse pollution; funded through the New Zealand Ministry of Business, Innovation and Employment, and ministry of Foreign Affairs and Trade. Key areas of interest include: treatment performance, nitrogen removal processes and modelling, role of wetland plants in treatment processes, ecological engineering.  Key participant in national research programs on the ecology and management of natural wetlands. Assessment of constructed wetland technologies in New Zealand, including treatment performance and practical problems associated with design, construction and operation.  Development of national design guidelines for wetland treatment systems for wastewaters, stormwaters and diffuse pollution.  Sanitation using natural systems with indigenous commuities in Fiji and New Zealand
