AirUCI grad student Avisa Charmchi has been named a 2024 UCI Beckman Scholar by the Arnold and Mabel Beckman Foundation.  Avisa is double-majoring in Chemistry and Biological Sciences studying non-linear chemistry from atmospheric oxidation of volatile organic compounds as part of a joint project between the research groups of AirUCI faculty. Sergey Nizkorodov (Chemistry) and Celia Faiola (Ecology and Evolutionary Biology and Chemistry). Each year, 1-3 outstanding students are selected as the Beckman Scholars based on their academic record, quality of previous research experience, and potential to become prominent research leaders in the chemical and life sciences. 

AirUCI faculty Mike Kleinman is quoted in a House Beautiful article on the health and environmental effects of backyard or campground fire pits.  Wood smoke is made up of fine particles, including soot and particulate matter 2.5, and also generate gases.  "Wood fire smoke contributes to air pollution and the fine particles contribute to lung and heart disease," Mike says.  "People who have respiratory problems are more likely to be at risk from health effects related to fire pit emissions, and those with pre-existing heart disease might also be at elevated risk when it comes to exposure to wood smoke."  The most dangerous instances of outdoor fire pit use include any that burn treated or painted wood or wood products— or if accelerants are used to get the fire stared — because those are very often toxic, Mike says.

Research conducted in AirUCI's Randerson, Czimczik, and Guenther groups points to increased instability in forest ecosystems.  In the Randerson group, AirUCI grad student Jinhyuk Kim led a study that found ecosystems at high latitudes are becoming increasingly unstable as a result of increased wildfires.  “We’re seeing higher levels of photosynthesis that persist for decades after fire,” said Jinhyuk. “Instead of the evergreen conifer forest coming back right away, in some regions, we see a long-term replacement of these forests with faster-growing species.”  In a study led by Allison Welch, AirUCI grad student in the Czimczik group, her team explored plant expansion across the Arctic ecosystem.  “With increasing temperatures and wildfire activity, we’re seeing increased growth of bigger, deciduous shrubs,” said Allison.

Hui Wang, AirUCI grad student in the Guenther group, conducted a third study which was focused on an unexpected rise in emissions of isoprene – an important molecule that influences local climate through its effects on ozone, aerosols, and methane levels.  “This change will indirectly change the climate,” said Hui, noting that rising temperatures have prompted plants to release more isoprene.  Read the article

AirUCI facutly Sarah Finkeldei is featured in an article about UCI's nuclear reactor facility.  Founded in 1969 by honorary AirUCI faculty Sherry Rowland, the facility has a storied history and Sarah's work is opening new possibilities and new collaborations.  Read the article
