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20世纪50年代的煤黑和多雾的伦敦到20世纪70年代的阳光明媚和交通尾气堵塞的洛杉矶发生了巨大变化。现在，它们正在经历另一个巨大的变化：由于排放法规，目前大多数车辆颗粒物排放来自非排气源，如制动灰尘和道路磨损;此外，由于气候变化，城市空气质量越来越受到野火颗粒物排放的影响。Styler博士的研究项目侧重于这些新兴颗粒物类别的化学反应性，从而深入了解它们所带来的空气质量，气候和健康挑战。
