My general research focus is on the influence of air pollution on both climate and human health. My specific interest is particulate matter (PM), and I have done a wide range of studies on the emission, formation, deposition and impacts of PM. I am particularly interested in how PM impacts climate by modifying the radiation balance of the atmosphere and I have done studies in both pristine regions of the world (Greenland and the Himalaya), as well as hazy regions (the Southeastern US, China, and India). More recently I have been studying the influence of PM on human health with emphasis on determining the relative contributions of sources (such as biomass burning and vehicular emissions) to acute health impacts. I am also involved in developing and deploying the next generation of air quality sensors to inform citizens on the quality of the air they are breathing so that they can make informed decisions to improve their air. My vision involves combining a multidisciplinary, multicultural approach to research and education that brings together researchers from around the world to collectively work together to make the air cleaner.
我的研究重点是空气污染对气候和人类健康的影响。我的具体兴趣是颗粒物(PM),我已对 PM 的排放、形成、沉积和影响进行了广泛的研究。我特别关注 PM 如何通过改变大气辐射平衡来影响气候,我在全球原始地区(格陵兰和喜马拉雅)以及雾霾地区(美国东南部、中国和印度)都进行了相关研究。最近,我一直在研究 PM 对人类健康的影响,重点在于确定不同来源(如生物燃料燃烧和车辆排放)对急性健康影响的相对贡献。我还参与了新一代空气质量传感器的开发和部署,以向公民提供他们呼吸的空气质量信息,以便他们能够做出明智的决策来改善空气质量。我的愿景是结合跨学科、多元文化的科研和教育方法,将世界各地的研究人员聚集在一起,共同合作,使空气更洁净。
