Research Interests

My research focusses on lakes, rivers and estuaries and their responses to changes in climate and land-use. 

My work spans a wide range of disciplines and scales of application from aquatic ecology to large-scale biogeochemical processes, and, from catchment scale experimentation to global scale policy analyses, respectively. I have led a series of national and international projects assessing ecosystem responses to the most pervasive threats to water resource security, globally, including nutrient and metal pollution and their interactions with climate change. I am the UKCEH Principle Investigator of Natural Environment Research Council National Capability Long-Term Science Multiple Centre projects delivering long-term and large-scale data on land-water-atmosphere nutrient interactions through freshwaters, from land to sea, with focus on the UK and polar ecosystems (e.g., LOCATE and BIOPOLE projects).

I led the Our Phosphorus Future project bringing together the international community to raise awareness on the need for more sustainable phosphorus use globally. My work informs large-scale ecosystem restoration initiatives, including on the recovery of lakes following nutrient pollution abatement, namely of phosphorus and nitrogen. I co-chair working groups of the International Society of Limnology and the United Nations Environment Programme (UNEP) World Water Quality Alliance to accelerate effective restoration practices, internationally.
