Professor Philip Haygarth of Soil and Water Science


Research Interests

My mission for CSWM and LEC is to help nurture research and complementing teaching to understand the key biological, physical and chemical processes that interact with water, colloid & nutrient release to catchments. The research will help build and inform new models that have policy relevance for national and global water management. My focus is on soils and their interactions with connected water-bodies, from catchment to coast, plant to planet.
