Renyi Zhang

Dr. Renyi Zhang is a **Harold J. Haynes Chair in Geosciences and University Distinguished Professor** of Atmospheric Sciences and Chemistry at Texas A&M University (TAMU). He holds a **PhD in Atmospheric Chemistry from MIT** (1994) and completed postdoctoral research at Caltech's Jet Propulsion Laboratory. His research focuses on **air pollution, climate change, stratospheric ozone depletion, and the airborne transmission of pathogens like COVID-19**. He has pioneered studies on aerosol formation mechanisms, including the chemistry behind the 1952 London Fog and severe Asian haze. His work bridges atmospheric science with public health, emphasizing the societal impacts of pollution and climate policies.

**Awards & Honors**: Humboldt Research Award (2024), Fellowships from AAAS, AMS, and AGU, and a **named symposium at the 2016 American Chemical Society meeting**. His interdisciplinary leadership includes founding the **Center for Atmospheric Chemistry and the Environment (CACE)** and guiding over 23 doctoral students, many now in academia, government, and industry.

**Research Interests**: Aerosol nucleation/growth, aerosol-cloud-climate interactions, ultrafine particle health impacts, and pandemic transmission dynamics. His team develops advanced instrumentation for atmospheric measurements and employs global climate models to assess anthropogenic influences on weather extremes and health.

**Grants & Advising**: Mentored 23 PhDs, 11 MSc students, 28 postdocs, and 14 exchange scholars. His students hold roles at NASA, NOAA, Stanford University, and industries like Intel. He serves on editorial boards of journals like *Journal of Geophysical Research* and chairs committees on atmospheric chemistry.

**Labs & Collaborations**: Active in TAMU's Atmospheric Sciences and Chemistry departments. Collaborates globally on field studies, including Mexico City and Houston air quality analyses. Integrates science with policy to address climate protection and public health challenges.
