Professor Seinfeld Elected to the National Academy of Sciences


Professor John H. Seinfeld has been elected to the National Academy of Sciences in recognition of his distinguished and continuing achievements in original research. His research has revealed the role of organic species in aerosols and the process by which vapor molecules become incorporated into particles. Currently his work focuses on the effects of aerosols on cloud formation and Earth's climate. [Caltech Release]

Researchers Help Improve Air Quality


John H. Seinfeld, Louis E. Nohl Professor and Professor of Chemical Engineering, is leading a group of researchers who, for the past month, have been zigzagging across the Los Angeles basin. Using an orange and white DeHavilland Twin Otter aircraft packed with instruments, the researchers have been sampling the air, measuring particles and pollutants to help policymakers improve air quality and dampen the impacts of climate change.

Effects of Soot on Global Warming


John H. Seinfeld, Louis E. Nohl Professor and Professor of Chemical Engineering, and colleagues from Carnegie Mellon University, and the Georgia Institute of Technology are studying the effects of soot on global warming. The research suggests that controls on black carbon soot might not slow global warming as much as previously thought. [CMU Article]

Paul Wennberg and John Seinfeld Show How Organic Carbon Compounds Emitted by Trees Affect Air Quality


Paul Wennberg, the R. Stanton Avery Professor of Atmospheric Chemistry and Environmental Science and Engineering and director of the Ronald and Maxine Linde Center for Global Environmental Science, and John Seinfeld, the Louis E. Nohl Professor and professor of chemical engineering, have shown that biogenic emissions—organic carbon compounds given off by plants and trees— affect air quality. Wennberg states that, "if you mix emissions from the city with emissions from plants, they interact to alter the chemistry of the atmosphere." Seinfeld adds, "particles in the atmosphere have been shown to impact human health, as they are small enough to penetrate deep into the lungs of people. Also, aerosols impact Earth's climate through the scattering and absorption of solar radiation and through serving as the nuclei on which clouds form. So it is important to know where particles come from." [Caltech Press Release]
