Dr. Liang-Hong Guo is Professor at the Institute of Environmental and Health Sciences, China Jiliang University, China. Dr. Guo received his Ph.D. in Chemistry from Oxford University, UK, in 1991, and carried out postdoctoral research at the University of Rochester, USA, from 1991-1995. He worked as Professor and Group Leader at the Research Center for Eco-environmental Science, Chinese Academy of Sciences, China, from 2004-2019. Dr.

Guo's research interests focus on toxicology and health impacts of new and emerging environmental contaminants including new flame retardants, fluorinated organic chemicals, and nanomaterials. He has published over 140 peer-reviewed articles in high-impact journals such as Environmental Health Perspectives, Nanotoxicology, Archives of Toxicology, and Environmental Science & Technology. Dr. Guo served as Editor-in-Chief of Chinese Journal of Environmental Chemistry and Associate Editor of Environmental Science: Processes and Impacts. Dr. Monika Mortimer is an Associate Professor in the Institute of Environmental and Health Sciences at China Jiliang University, Hangzhou, China. She received her B.Sc.

, M.Sc. and Ph.D. in Chemistry from Tallinn University of Technology, Estonia. She was a recipient of a postdoctoral grant from the Rectors' Conference of the Swiss Universities to conduct research at the University of Geneva, Switzerland in 2012-2013. In 2014, she received a postdoctoral grant from the Estonian Research Council for research at the University of California, Santa Barbara (UCSB) and the UC Center for Environmental Implications of Nano-technology (UC CEIN). She continued her appointment with UCSB as a Project Scientist in 2016-2019.

Her research focuses on environmental and health im-pacts of engineered nanomaterials and emerging pollutants. Her areas of expertise include microbiology, molecular toxicology, omics approaches, nanomaterials, and environmental fate and effects of chemicals. She serves as an Academic Editor of PeerJ and an Associate Editor of Biogeochemical Dynamics, a specialty section of Frontiers in Environmental Science.
