Dr. Xiaoguang Ouyang is a research fellow at Simon F.S. Li Marine Science Laboratory, School of Life Sciences, The Chinese University of Hong Kong. His research focuses on coastal wetland ecology, with recent research interest in carbon cycling, ecosystem services and decision-making. He acts as the co-chair of the session entitled ‘Greenhouse gasses: Production, uptake, and emission’ at the ECSA 57 conference. He is the advisory board member of Cambridge Scholar publishing, and reviewers of reputable journals, such as Science of The Total Environment, Global Biogeochemical Cycles and Biogeosciences. Professor Shing Yip Lee is the director of Simon F. S. Li Marine Science Laboratory, co-director of Institute of Environment, Energy and Sustainability at The Chinese University of Hong Kong and Chair of Mangrove Specialist Group, International Union for the Conservation of Nature. His research interest focuses on ecology and biogeochemistry of estuarine wetlands such as mangroves and saltmarshes, application of stable isotopes in marine environmental research, as well as marine ecosystem dynamics, rehabilitation and restoration. Dr. Yuk Fo Derrick Lai is an Associate Professor in the Department of Geography and Resource Management, The Chinese University of Hong Kong. His research interest includes but not limited to carbon cycling in terrestrial and wetland ecosystems, as well as ecosystem restoration and management. Dr. Cyril Marchand is a Professor of Earth Sciences at the University of New Caledonia. He is specialized in mangrove sediments biogeochemistry, with a focus on carbon cycling including stocks, processes and fluxes. He is also interested in the influence of climate changes on carbon cycling in mangroves, and developed many research projects in French Guiana, New Caledonia, New Zealand, and Vietnam.
