Pengfei Liu

Pengfei Liu is an Assistant Professor in the School of Earth & Atmospheric Sciences at the Georgia Institute of Technology (Georgia Tech), within the College of Sciences. His research focuses on atmospheric chemistry and aerosols, particularly their roles in climate interactions and air quality. He holds a Ph.D. in Environmental Science and Engineering from Harvard University (2017), an M.S. in Atmospheric Physics and Environment from Peking University (2011), and a B.S. in Atmospheric Sciences from Peking University (2008).

Dr. Liu’s research interests span aerosol-climate interactions, organic particulate matter properties, and biomass burning emissions across timescales. He investigates how atmospheric aerosols influence cloud formation, fog microphysics, and long-term environmental changes using laboratory experiments and advanced modeling techniques. His work also addresses mercury emissions in India, regional air quality policies, and the health impacts of air pollution exposure in older populations.

His publications highlight innovative approaches to measuring aerosol hygroscopicity, refining emission inventories, and exploring the chemical reactivity of particles under varying environmental conditions. Notably, he has contributed to improving historical biomass burning emission estimates using ice core data and inverse modeling, with implications for global climate forcing. Collaborations involve interdisciplinary projects linking atmospheric chemistry, public health, and machine learning.

Though no specific advisees or awards are listed, his research is supported by grants addressing topics such as aerosol optical properties, regional climate dynamics, and environmental health disparities. He actively engages in field studies and model development to advance understanding of anthropogenic and natural aerosol processes.
