I am an Assistant Professor in the Department of Civil Engineering. My research focuses on water and wastewater treatment strategies, environmental impact assessment, and risk management. My research activities are interdisciplinary and have commonalities with the fields of environmental and chemical engineering, environmental chemistry, analytical chemistry, and microbiology. My expertise lies in advanced oxidation process, biodegradation, biofiltration, and bubble technology. I am fascinated by the treatment of toxic bacteria, algae, biotoxins, antibiotic resistant bacteria/genes, and emerging contaminants (e.g. pharmaceuticals and personal care products, flame retardants, microplastics). My expertise also lies in Synchrotron Radiation and the associated techniques to solve a variety of challenges in analytical chemistry.

Previously, I worked as a postdoctoral fellow in Memorial University of Newfoundland (201910-202106). Prior to my arrival at Queen’s University, I worked as a research assistant professor at State Key Laboratory of Marine Pollution and the School of Energy and Environment in the City University of Hong Kong (202109-202208). 

I obtained my PhD degree in environmental system engineering at the University of Regina in Regina, Canada. I received my BSc in Environmental Science from Yangzhou University, China. 

My research is primarily focused on:

  • Water and Wastewater Treatment
  • Harmful Algal Bloom
  • Emerging Contaminants
  • Environmental Impact Assessment and Risk Management
  • Synchrotron Radiation-based Techniques and Environmental Applications
CIVL 472 Water Treatment
