About me

I received the B.S. degree from Tongji University, Shanghai, in 2020, and the M.S. degree from Nanyang Technological University, Singapore, in 2022. I am currently a Ph.D. student in Nanyang Technological University, Singapore. My main research interest is the behavior and long-term fate of waste in landfills, especially plastics. I also work on estimation and mitigation of greenhouse gas (GHG) emissions from solid waste disposal sites (SWDS).


08.2022 ~ Current, Ph.D., Environmental Engineering, Nanyang Technological University

08.2020 ~ 06.2022, M.Eng. (M.Phil.), Environmental Engineering, Nanyang Technological University

09.2016 ~ 07.2020, B.S., Environmental Science, Tongji University


My research interests include:

  • Waste management

  • Plastics & Microplastics

  • Climate change
