My research focus revolves around the chemistry of solid and liquid particles in the atmosphere, i.e., particulate matter (PM). We are primarily interested in airborne "dust," which is resuspended soil and sand debris from arid regions and can be transported 1000s km, and even around the globe.
From the perspective of dust, we are interested in both its source, using stable metal isotopes as a tool to trace the dust, and the chemistry of the dust as it is transported through the atmosphere. As iron is the most abundant transition element in PM, we focus on how iron is solubilized and transformed during transport. We are also interested in the interactions between the iron and organic fractions of the PM, including photochemistry and aqueous cloudwater chemistry.
