Associate Professor of Biogeochemistry
Director of Graduate Studies, Ecology PhD program (UPE)
I am an ecosystem ecologist and biogeochemist whose research is principally concerned with tracking the movement of elements through ecological systems. My research aims to document the extent to which the structure and function of aquatic ecosystems is being altered by land use change (urbanization, agriculture, mining) global change (rising CO2, rising sea levels) and chemical pollution. Ultimately this information is necessary to determine whether and how ecosystem change can be mitigated or prevented through active ecosystem management.
