PhD Position in Urban Climate and Air Quality Modeling and Measurements at the University of Southern California
Are you enthusiastic about leading the way in research to address urban climate and air pollution challenges? Join Dr. Jiachen Zhang's research group (https://sites.usc.edu/jzhang/research/), which is at the forefront of urban climate and air quality modeling and policy impact assessment.
We are seeking a PhD student (starting Fall 2027) to work on one or more of the projects below:
- Assess the impact of energy and transportation policies (e.g., policies promoting electric vehicles) as well as data centers on urban climate, air quality, health, and equity
- Improve the representation and simulation of per- and polyfluoroalkyl substances (PFAS) in atmospheric models
- Simulate smoke transport and chemistry during wildland–urban interface (WUI) fires.
- Integrate air quality modeling output with various observational data using machine learning techniques
- Conduct aerosol sampling and measurements to identify pollution sources
- Applicants are also encouraged to propose research ideas aligned with their interests that resonate with the overarching research objectives of Dr. Zhang's research group.
We welcome candidates with some of the following qualifications:
- Passion for addressing critical societal challenges related to climate and air quality through research and outreach
- Proficiency with air quality and climate modeling tools such as WRF, WRF-UCM, WRF-Chem, WRF-CMAQ, AERMOD, CESM, and GEOS-Chem
- Proficiency in machine learning techniques and computer programming (e.g., Python, MySQL, R, and Excel), including hands-on experience with complex datasets and statistical analysis.
- A strong background in engineering or science, such as coursework with strong GPA, and/or research experience in Environmental, Mechanical, or Chemical Engineering, Atmospheric or Earth sciences, Environmental Health, or related fields
Prospective students may reach out to Dr. Jiachen Zhang at jiachen.zhang@usc.edu before December 1st. Please use the subject line “PhD-2026-[Name]”, and combine the following documents into one PDF, and attach it to your email:
- Curriculum Vitae (CV)

Biography of Dr. Jiachen Zhang (https://sites.usc.edu/jzhang/)
Dr. Jiachen Zhang is a tenure-track Assistant Professor in the Department of Civil and Environmental Engineering at the University of Southern California (USC). She is also affiliated with the Department of Population and Public Health Services and the Spatial Sciences Institute at USC. Her research group investigates the interactions of air quality, climate, and society, quantifying the health and equity impacts of strategies aimed at mitigating climate change and air pollution.
Dr. Zhang holds a Ph.D. in Environmental Engineering from USC and a B.S. in Atmospheric Sciences from Peking University. During her doctoral and postdoctoral studies, she utilized and enhanced various climate and air quality models to assess the environmental impacts of adopting solar reflective cool surfaces, renewable energy, and electric cars. Prior to returning to USC, Dr. Zhang was a manager in the Air Quality Planning and Science Division at the California Air Resources Board, where she led a team of scientists and engineers to conduct original research projects, develop emissions inventory, and inform first-of-their-kind policies aimed at promoting electric vehicles and reducing air pollutant emissions. Additionally, she serves as the secretary of the Air & Waste Management Association West Coast Section.
