Research interests

Dr. Medeiros (he/him) research interests focus on understanding the influence of environmental stress on freshwater systems, past, present, and future. He is particularly motivated in applying new methodologies to community-based research in the Arctic. His current research projects outline the influence of environmental change on aquatic trophic systems. This includes investigation of water security through the lens of sustainability and conservation, municipal planning, and engineering for freshwater supply services.
