Dr. Wu is a Full Professor in the program of Environment and Sustainability at the School of Science and the Environment, Grenfell Campus, Memorial University. Dr. Wu is also an affiliated faculty member of Ph.D. and M.Sc. Program in Boreal Ecosystem and Agricultural Science (BEAS), Interdisciplinary M.Sc. and Ph.D. program in Environmental Science, and Ph.D. program in Transdisciplinary Sustainability. 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, nitrogen cycling and greenhouse gas emissions), of boreal peatlands, forests and agriculture. 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 climate change and human disturbances (such as drainage, peat mining, and restoration) affects the greenhouse gas emissions from boreal peatlands, and how different management scenarios affect greenhouse gas emissions in boreal agriculture. His research program is involved in both modelling and empirical observation and field measurements.
