Overview

Dr. Dickson’s expertise is in the field of hydrogeology, with a focus on fractured rock systems. She and her graduate students conduct research on the characterization of these systems, and investigate the transport and fate of particulate and chemical contaminants within them. A comprehensive understanding of these systems is required to inform aquifer vulnerability studies, and thus the risks posed to drinking water sources. Dr. Dickson brings this background to the study of local water security, particularly in rural, remote, and Indigenous communities. She collaborates with other disciplines towards a holistic understanding that encompasses the physical, social, cultural, and economic elements of local water security.
