Professor Jesse Kroll has received a National Science Foundation (NSF) CAREER award for his project, “Photochemical Aging of Atmospheric Organic Aerosol: Chamber Studies of the Chemical Evolution of Oxidized Organic Species.” The Faculty Early Career Development (CAREER) Program is NSF’s most prestigious awards for researches early in their careers. They recognize “activities of those teacher-scholars who most effectively integrate research and education within the context of the mission of their organization.” Kroll’s project addresses the chemical evolution of organic aerosol (OA) through laboratory studies of the photochemical aging of oxidized organics.  The results of this work will inform policy on aerosol-climate and aerosol/health interaction and promote the scientific development of students.
