The air pollution challenges facing urban populations changed substantially from coal-blackened and foggy 1950s London to sunny and traffic exhaust-choked 1970s LosAngeles. Now, they are undergoing another dramatic change: as a result of emissionregulations, most vehicular particulate emissions currently arise from non-exhaustsources like brake dust and road wear; in addition, as a result of climate change,urban air quality is increasingly influenced by wildfire particulate emissions. Dr.Styler's research program focuses on the chemical reactivity of these emergingclasses of particulate matter, and thereby provides insight into the air quality,climate, and health challenges that they pose.

城市人口面临的空气污染挑战从1950年代伦敦的煤 - 黑色和雾气造成的变化发生了很大变化，转变为阳光明媚的阳光和交通排气的1970年代洛杉矶。现在，他们正在经历另一个戏剧性的变化：由于排放量，大多数车辆颗粒物排放量目前来自诸如制动灰尘和道路磨损之类的非排量库；此外，由于气候变化，城市空气质量越来越受野火颗粒物排放的影响。 Styler博士的研究计划着重于这些颗粒物的这些出现级别的化学反应性，从而洞悉了它们所带来的空气质量，气候和健康挑战。
