About Me

Here is Yifei Lin (Forwood, 林奕妃).
I am a first-year Ph.D. student at the School of Environment, Tsinghua University, supervised by Professor Bin Zhao in the Air Pollution and Climate Research Team. My doctoral research focuses on the numerical modeling of atmospheric aerosols.
I completed my undergraduate studies at Peking University with a double degree: a Bachelor of Science (B.Sc.) in Environmental Science from the College of Environmental Sciences and Engineering , and a Bachelor of Engineering (B.Eng.) in Energy and Environmental Systems Engineering from the College of Engineering, as a student of the Beyond Boundary Program (BBP).

If you are interested in any aspect of me, I am always open to discussions and collaborations. Feel free to reach out to me at yf-lin26@mails.tsinghua.edu.cn
Research Interests
- Atmospheric Aerosol Modeling
- Aerosol Formation and Evolution
- Aerosol-Cloud Interactions
- Development and Application of Atmospheric Chemistry Models
My current research focuses on reducing the uncertainties in simulating atmospheric particulate matter (PM) within air quality models. These uncertainties largely arise from inadequate representations of complex, nonlinear feedback effects governing aerosol formation and evolution — including new particle formation, gas-particle partitioning, chemical aging, and deposition.
Building on my undergraduate thesis, “Consistency Assessment, Optimization, and Application of an Integrated Model for the Formation and Transformation of Atmospheric Particulate Matter” , I am now working to implement and evaluate these feedback mechanisms — mediated by the dynamic evolution of particle properties such as phase state, mixing state, hygroscopicity, and size distribution — within integrated aerosol process models. Through sensitivity experiments, my research aims to quantify the impact of these interactions on PM concentrations and properties, improving predictive capabilities for heavily polluted regions.
My ultimate goal is to advance the understanding of air pollution and its climatic impacts through numerical modeling, contributing to science-based solutions for global sustainability.
