About Me

Here is Yifei Lin (Forwood, 林奕妃).
I am an undergraduate student in the College of Environmental Sciences and Engineering at Peking University, as well as a student of Beyond Boundary Program (BBP), pursuing a Bachelor of Science (B.Sc.) in Environmental Science.
I am also pursuing a double degree in Energy and Environmental Systems Engineering (B.Eng.) at the College of Engineering, Peking University.
For more details, please refer to my resume
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 yflin@stu.pku.end.cn
I will be joining the School of Environment at Tsinghua University in the Fall of 2026 as a Ph.D. candidate. Under the supervision of Professor Bin Zhao, I will be part of the Air Pollution and Climate Research Team, focusing on the numerical modeling of atmospheric aerosols.
Research Interests
- Atmospheric Aerosol Modeling
- Air Quality and Climate Change
- Environmental-Economic-Energy Systems Modeling
My current research addresses a critical challenge in atmospheric science: the significant uncertainties in simulating atmospheric particulate matter (PM) within state-of-the-art air quality models. These inaccuracies often stem from an inadequate representation of the complex, nonlinear feedback effects among the various processes governing aerosol formation and evolution, such as new particle formation, gas-particle partitioning, chemical aging, and deposition.
My undergraduate thesis, “Simulation and Assessment of Interactive Effects in the Formation and Transformation of Atmospheric Particulate Matter Components,” focuses specifically on this gap. I am working to implement and evaluate these crucial feedback mechanisms—which are mediated by the dynamic evolution of key particle properties like phase state, mixing state, hygroscopicity, and fine-particle size distribution—within a newly developed, integrated aerosol process model. Through controlled sensitivity experiments, my project aims to quantify the impact of these interactions on PM component concentrations and properties, thereby improving the model’s predictive capabilities for heavily polluted regions like Beijing-Tianjin-Hebei.
I am committed to becoming a versatile researcher who can contribute to innovative solutions for global sustainability. My ultimate goal is to use my skills in numerical modeling and systems analysis to advance our understanding of air pollution and its climatic impacts.
