Research Interests

Aerosols are generated by a variety of natural and anthropogenic sources. I am interested in the processes that emit, transform and deposit particulate matter. A current focus of my research is how particles in the atmosphere directly modify the surface radiation balance of the Earth. This is of importance to the climate of the Earth, as well as plant growth and visibility. We have conducted studies at a variety of polluted urban sites as well as pristine remote sites to understand the contrast between clean and dirty locations. Another interest is the past impacts of aerosols on climate through interpretation of paleorecords archived in ice cores. My work involves a combination of lab and field studies as well as the development of relatively simple mathematical models.

Bio

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.
