Research Area: Wetlands

Peter Randerson

Peter’s research covers pollutant removal and nutrient recovery from effluents and waste water (biofiltration), using constructed wetland systems and the production of biomass crops.

More information on Peter’s institutional profile.

Steve Ormerod

With a research focus on global change effects on freshwater organisms and ecosystems; river biodiversity and ecosystem services Steve is a leading specialist in riverine and wetland bird ecology.

Jannis Wenk

Jannis Wenk

Jannis’ research investigates both physical and chemical water treatment, including developing more efficient technologies for gas transfer, investigate novel types of process combinations in engineered and nature-oriented treatment scenarios, such as constructed wetlands,  and to further explore oxidative water treatment for example, ozonation, UV-light and radical induced processes as an important step to remove aqueous contaminants, pathogens and avoid spread of antimicrobial resistance. Current research in his group also investigates fate of microplastics in constructed wetland and separation technologies for microplastics.

Barbara Kasprzyk-Hordern

Barbara Kasprzyk-Hordern

Barbara’s research focuses on environmental pollution, environmental epidemiology, water quality/water treatment and analytical chemistry. Barbara is particularly interested in water pollution and novel technologies used to decrease contamination of water. Recent interests are related to urban water and human epidemiology.

Lee Bryant

Lee Bryant

Lee researches oxygen in natural systems and its influence on water quality. Lee works on aerating reservoirs in partnership with Jersey Water, Welsh Water and Bristol Water, looking at manganese and nutrients. Lee also works with modellers on predictive capability. Finally, some of Lee’s work is conducted in Africa (Sierra Leone) on urban agriculture schemes involving constructed wetlands.

Jan Hofman

Jan Hofman

Jan’s research focuses on sustainable solutions in the water cycle, sustainable water management, and water security. Jan also studies the origin, fate and abatement options for emerging contaminants, thermal energy recovery from water and wastewater and resource recovery from wastewater and water treatment residuals. Finally, Jan’s work involves water demand and sewer modelling and water treatment.
