Associate Professor – Sustainable Resource Management

Profile

Dr. Wu is an Associate Professor in the program of Sustainable Resource Management at the Division of Social Science, Grenfell Campus: Memorial University. Dr. Wu is also an affiliated faculty member of M.Sc. in Boreal Ecosystem and Agricultural Science (BEAS), and Interdisciplinary M.Sc. and Ph.D. in Environmental Science. His general research interests are environmental modelling, terrestrial and aquatic biogeochemical cycling, ecosystem ecology, climatic and environmental change, spatial hydrology and geographic information science.  More specifically, his research focuses on how climate change and human/natural disturbances influence the hydrological and biogeochemical processes (especially carbon and nitrogen cycling), of boreal ecosystems. Dr. Wu's research, focusing primarily on the biogeochemistry of ecosystem dynamics, is motivated by the need of policy-relevant science for the practical application to mitigation but more, given the current state of the climate situation, to adaptation, as the particular ecosystems he has focused on, northern peatlands, have been identified by the Global Carbon Project as one of the potential 'carbon bombs' – i.e. they become a large positive feedback due to their very large store of organic carbon and their role in the global methane cycle. Dr. Wu's present projects are to examine how agricultural development affects the greenhouse gas emissions from boreal peatlands and/or boreal forests. His research program is involved in both modelling and empirical observation and field measurements.
