Research Assistant Professor School of Environmental Science and Engineering   Research Group

Dr Chen obtained his PhD in the Hong Kong University of Science and Technology. He is currently a Research Assistant Professor in the School of Environmental Science and Engineering, Southern University of Science and Technology. His research focuses on 1) the effects of plant-microbe interactions on plant responses such as heavy metals/metalloids uptake, metabolism and ecosystem functions (e.g. cellulose biosynthesis), 2) ecological restoration in degraded lands such as landfill and filled slope in urbanized area, and 3) biofactors in affecting soil physical stability (e.g. slope failure problem).
