Published Research

My earliest research began at the National Renewable Energy Laboratory, where I contributed to development and evaluation of novel methods to mediate aqueous and gaseous waste streams using heterogeneous, solar photocatalytic approaches.

My doctoral research at CU Boulder focused on atmospheric particulate matter and heterogeneous gas/solid atmospheric chemistry. I developed and characterized an aerosol inlet designed to separate atmospheric aerosol particles from interstitial air to eliminate gas-phase interferences in chemical analysis. Another part of my thesis research involved field testing a prototype instrument by measuring ozone concentrations within the arctic boundary layer at Summit, Greenland as part of a broader mission to characterize reactions of tropospheric oxidants in the upper, porous layer of the snowpack.

My postdoctoral research at SRI International - and my early research with undergraduate students at UW-Eau Claire - extended my focus on heterogeneous atmospheric chemistry research to reactions on the surfaces of particles found in the upper atmosphere (ca. 85 km). These included recombination reactions of monatomic oxygen on amorphous water ice and mineral particles at very low temperatures.

Recently, I have expanded my scholarly work to include elements of the social sciences and policy, collaborating with faculty colleagues in economics and communications. The context of this work is consistent with my focus on atmospheric sciences, gauging public perceptions of climate change science and mitigation policy approaches in the US and China.

My current chemistry research is related to analytical method development for atmospherically relevant trace constituents. Currently, we are working on in situ quantification of airborne respirable silica particulate matter using a novel, highly sensitive chemiluminescent analytical approach. This draws on some of my earliest work as a grad student.
