Atmospheric chemistry, exposure to air pollution, instrumentation development
I got my PhD at Center for Atmospheric Particle Studies, Carnegie Mellon U., Pittsburgh PA. My PhD thesis title was "Pre-existing and Potential Particulate Patterns in Populous Places: Probing Pollution Parity for the Poor and the Prosperous" (alliteration very much intended). My first paper in Atmos. Chem. Phys. describes the "pre-existing" patterns of particulate matter, and their sources, in Oakland, CA. My second paper in Env. Sci. Tech. describes the "potential" particulate matter sources, for which I did measurements in Pittsburgh and New York City metro areas. My third paper (in prep.) focuses on socio-economic (dis)parities in exposure to urban particulate matter. An unplanned four paper is also in the works, but its in a very nascent stage.
I am currently developing a method for external calibration of an Aerosol Mass Spectrometer, by measuring aerosol-phase total reactive nitrogen and carbon (Nr and Cy). The instrumentation measuring Nr and Cy has been characterized previously (Stockwell et al. Atmos. Meas. Tech. 2018). One objective of this project is to better understand and quantify the various aspects of aerosol mass spectrometry such as collection effiency for different atmospherically-relevant compounds.
