Dr. Xiaying XIN

PhD in Environmental System Engineering, University of Regina, Canada
Staff title
Visiting Assistant Professor
Research Assistant Professor (SKLMP)

Dr. Xin received her Ph.D. in environmental system engineering from University of Regina in 2019, and worked as a postdoctoral Fellow in the Northern Region Persistent Organic Pollutant lab in Memorial University of Newfoundland from 2019 to 2021. She also worked for the Institute for Energy, Environment and Sustainable Communities and the Persistent and Emerging Organic Pollutants in the Environment (PEOPLE) CREATE Network of Canada. She is currently working as Research Assistant Professor at State Key Laboratory of Marine Pollution (SKLMP), holding a concurrent appointment as Visiting Assistant Professor at School of Energy and Environment (SEE), CityU.

Other Information

Research Interests

Dr. Xin’s research focuses on the fates and effects of Emerging Contaminants of Concern (ECCs), particularly in the area of environmental risk assessment. Her research focuses on exploring the interactive effects and mechanisms of ECCs (eg. pharmaceuticals and personal care products, flame retardants, microplastics, nanoparticles, etc.) that lead to various responses in microalgae and the effects through trophic interactions. Her research also applies molecular docking, molecular dynamics simulations and machine learning assisted quantitative structure-activity relationship model to conduct environmental risk assessments. She has interests in how environmental factors affect the fates and effects of ECCs under different climate change scenarios. She also has interests in applying nanotechnology and biotechnology for water/wastewater contaminant removal.
