Graduate students

Paige Aiona

Paige Aiona graduated from Chapman University in 2012, where she did research on water chemistry. She is studying the photochemistry and molecular level composition of light-absorbing aerosols know as "brown carbon". She uses UV-Vis and fluorescence spectroscopy to measure the optical properties, and high resolution mass spectrometry to investigate the molecular level composition. View Paige's curriculum vitae.

Sandra Blair

Sandra Blair joined the UCI chemistry graduate program after graduating from California State University, Chico. She started her graduate research in the lab in June 2011. She studies the chemical composition of anthropogenic and biogenic organic aerosols using various techniques, and the SOA aging processes induced by gaseous pollutants and/or solar radiation. Sandra Blair's LinkedIn page.

Lauren Fleming

Lauren Fleming graduated from the College of Wooster in 2014. Her honors thesis focused on aqueous photochemistry. In our group, she is investigating photochemistry of biomass burning aerosols in controlled environments and in the field, using mass spectrometry and UV-Vis absorption techniques. She also is a part of the Rowland- Blake group where she analyzes the gaseous products of biomass burning. View Lauren's curriculum vitae.

Mallory Hinks

Mallory Hinks received her bachelor and MS degree in chemistry from San Diego State University in 2011, where she researched surface chemistry in the laboratory of David Pullman. Mallory is investigating the effect of temperature and relative humidity on the photochemical kinetics of organic molecules embedded in secondary organic material (SOM). By altering both the temperature and relative humidity, she is able to study the effect of SOM viscosity on these processes. View Mallory's curriculum vitae and watch a short video where she talks about her research.

Amanda MacMillan

Amanda C. MacMillan is a graduate of the University of Central Arkansas. She joined the group in 2009. Amanda's first research project deals with mechanisms by which water molecules adhere to nanometer-size particles, a fundamentally important process for the formation of cloud and fog droplets. She is also studying the mechanism of SOA formation from diesel fuels and other VOCs. View Amanda's curriculum vitae.

Julia Montoya

Julia Montoya joined the UCI chemistry graduate program in the summer of 2015 after graduating from Cal State LA, where she did research on production of singlet oxygen from PAH compounds. She joined our group in February 2016. She is investigating the effect of ammonia on the composition and properties of secondary organic aerosols using DART mass spectrometry and other methods.

Kurtis Malecha

Kurtis Malecha studied chemistry at the Minnesota State University, Mankato. He joined the group at the beginning of 2014. He investigates mechanisms of production of volatile organic compounds (VOCs) during condensed-phase photolysis of secondary organic aerosols (SOA). Current air quality models underpredict many of these VOC levels in the atmosphere, so understanding their formation is crucial to better air quality models. Personal website.

Dian Romonosky

Dian Romonosky graduated from the chemistry department at Millikin University in 2011. She joined the group in early 2012 to do research on the formation, optical properties, and aqueous photochemistry of SOA generated from various biogenic and anthropogenic precursors under different conditions, using primarily HR-MS techniques.   She is interested in how the molecular composition of SOA differs between samples as well as how it changes with irradiation, with a particular emphasis on nitrogen-containing compounds.
