I am a PI of the Environmental and Public Health (EPI) Research Group and a Professor at the Department of Environmental Science and Engineering at Xi’an Jiaotong University (XJTU). XJTU is a member of China’s C9 league and ranked among the top five in Science and Engineering in the country.


The overall theme of my research is on emerging contaminants, and much of my previous work was on the migration of trace organic compounds, into and out of, polymers including membranes, plastics, and elastomers. I have a strong interest in public health including risk identification, assessment, mitigation, and scientific communication to the public.


Prior to joining XJTU, I received research training and experience from the University of Auckland (UoA), National University of Singapore (NUS), University of Illinois at Urbana Champaign (UIUC), and University of Massachusetts Amherst (UMass Amherst), and worked with the PIs of several world-renowned laboratories in my fields. Since my Auckland times, I have supervised about 20 students, including several undergraduates who later developed strong interests in scientific research and pursued their PhDs. To date, I have delivered several research projects as the PI with about 3.5 million yuan in funding.

Why plastics

My inadvertent journey on polymers (and scientific research in general)




Our current research covers the following domains:


1) Plastics and rubbers (bulk, micro, nano) as anthropogenic contaminants


2) Interactions between polymers - chemicals - biological substances


3) Applications and implications in environmental and public health domain



We seek students, postdocs, and collaborators from polymer science, environmental science, biology and microbiology, and life science related disciplines to conduct further work in these research domains.
