Atmospheric Chemistry

城市人口面临的空气污染挑战发生了巨大变化，从20世纪50年代煤黑多雾的伦敦，到20世纪70年代阳光明媚、交通拥堵的洛杉矶。现在，它们正在经历另一场戏剧性的变化：由于排放法规，目前大多数汽车微粒排放来自非废气来源，如刹车灰尘和道路磨损；此外，由于气候变化，城市空气质量越来越受到野火颗粒排放的影响。斯特勒博士的研究项目主要集中在这些新出现的颗粒物的化学反应性上，从而为空气质量、气候和健康带来的挑战提供见解。

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.
