Welcome

Welcome to the Aerosol Photochemistry Group. We are located on the beautiful campus of the University of California, Irvine in the Department of Chemistry. We investigate chemical composition, photochemistry, and physical properties of organic aerosols using aerosol chamber techniques, mass spectrometry, and other state-of-the-art techniques. Please refer to our research section for more details (note that this section is less up to date than the publication section).

Announcements

Aeronews:

• Dr. Zhaomin Yang has finished her one-year postdoc at UCI at the end of June 2026. She be joining Qingdao Institute of Marine Meteorology, Chinese Academy of Meteorological Sciences. We will miss you Zhaomin!
• Our group welcomes Chem-SURF student from Carleton College, Benjamin Young. Ben will work with Erik Jackson and Matt Zaragoza on acid-catalyzed chemistry in biomass burning aerosols.
• Lena Gerritz successfully defends her Ph.D. thesis "Radical Insights into Aqueous Photochemical Aging of Secondary Organic Aerosols and Atmospheric Surrogate Mixtures" on June 16 in front of her committee, Profs. Annmarie Carlton, Sergey Nizkorodov, and Manabu Shiraiwa, and a large number of AirUCI members. Congratulations Dr. Gerritz!

Graduate Research: If you are interested in conducting graduate research in our group please contact Prof. Nizkorodov. We typically try to have 1-2 new graduate students join our group each year.  Please refer to the publication section for examples of recent papers by the group members. The group's graduate students have been recognized by multiple awards and fellowships from the department and from the outside sources. Former group members have been successful in securing employment in policy, education, industrial research and academic research sectors. Go Aerosolates!

Undergraduate Research: Undergraduate students are welcome to do their undergraduate research projects in Aerosol Photochemistry Group on a space available basis. We typically have 3-5 students at any given time (depending on whether a graduate student mentor is available). If you are interested in such an opportunity please review the requirements and then contact Prof. Nizkorodov in advance. The usual mechanism is enrollment in either Chem 180, H180, or 199; summer internships may be possible as well. We cannot take high school interns.
