I am currently undertaking a PhD student at 🌍the Department of Earth and Environmental Sciences, The University of Manchester, UK, supervised by Dr. Zhonghua Zheng (Assistant Professor in Data Science & Environmental Analytics), Chair Professor David Topping (Professor of Digital Environment, Fellow of the Alan Turing Institute), and Chair Professor Hugh Coe (Professor of Atmospheric Composition). I also serve as a reviewer for the ES&T Air and Journal of Geophysical Research: Atmospheres (JGRA)
My research interests encompass the development and application of advanced modeling and data-driven approaches to address key challenges in atmospheric science. Specifically, I focus on particle-resolved aerosol dynamic modeling to capture the detailed evolution of aerosol populations, cloud parcel modeling to investigate aerosol–cloud interactions, and the integration of machine learning techniques to enhance the prediction and understanding of complex atmospheric processes. I focus on aerosol mixing states, black carbon, and atmospheric nanoplastics, aiming to quantify their environmental behavior and radiative impacts through data-driven and mechanistic approaches.
🔥 News
- 2025.06: 🎉🎉 I am happy to be one of important contributors of The University of Manchester Open Research Award 2025. This award recognises individuals and teams who have made significant contributions to Open Research at Manchester (awarded one for each year).
- 2025.05: 🎉🎉 Excited to present my work at EGU 2025: “Integrating Simulations and Observations: A Foundation Model Approach to Aerosol Mixing State Index Estimation”
- 2025.04: 🎉🎉 My first PhD paper, “Integrating Simulations and Observations: A Foundation Model Approach to Aerosol Mixing State Index Estimation,” has been published. We propose a machine learning (deep learning) foundation model using pre-training (on particle-resolved simulation data) and fine-tuning (with limited observations/measurements) to estimate aerosol mixing states under real-world conditions. Grateful to all co-authors, editors, and reviewers for their support.
