Prof. Li’s major research interests include regional environmental pollution, urban environment, and remediation of contaminated soils. His recent research projects have mainly focused on environmental changes in the fast developing regions. Prof. Li’s research team has been engaged in the study of trace metals and organic pollutants in atmospheric particles, soils, sediments, and biological samples, including their impacts on human health and ecological systems. He has been the principal investigator of numerous research projects funded by RGC, NSFC, and the UGC Area of Excellence Scheme. He has published more than 250 papers, mostly in leading international journals. Prof. Li is the author of more than ten publications listed among the top 1% most cited papers in Environment/Ecology by the ISI database. His current research topics consist of the emissions, transport and environmental fate of metal and organic pollutants, and the environmental loadings and implications of emerging pharmaceutical related contaminants in surface environments. He is Deputy Editor of ACS Environmental Au, and an associate editor of Environmental Science and Technology (ES&T).
