Susan Hegarty is a geographer and Associate Professor in the DCU School of History and Geography, where she is currently Head of School. Her research focuses on citizen science for monitoring water quality, and on the evolution of the Irish landscape and our use of that landscape. She has researched the role of the Quaternary ice-sheets on this landscape and the role Quaternary sediments play in the vulnerability of water sources to pollutants. She is also interested in the exploitation of Irish mineral resources in the nineteenth century.
She is enthusiastic about transmitting the importance of Geography to the wider public, and to this end has taken part in a number of documentary series on both Irish and British television channels and is involved in a number of citizen science projects looking at water quality in Ireland. She also sees fieldwork as an integral part of the training of geography students, and promotes field studies within undergraduate geography. She is a Senior Fellow of the Higher Education Academy.
