Research Interests

As Professor at the University of Colorado (Chemistry Department) in Boulder, Colorado my teaching in Instrumental Analysis with Environmental Emphasis (undergraduate level), and Analytical Spectroscopy (graduate level) is often enhanced by my research in Atmospheric Chemistry to inform Chemistry-Climate interactions, Energy & the Environment. My research group develops instrumentation (in-situ optical spectroscopy & sub-orbital remote sensing) to solve Analytical & Physical Chemistry problems in the real-world, e.g., to better quantify sources (air-sea exchange, urban, agriculture, biomass burning, etc), characterize aerosols (optical closure), and to probe mechanisms by which gases modify aerosols, oxidative capacity, atmospheric mercury, tropospheric O₃, and CH₄.

Current Research

Tropospheric Halogens in the Remote Free Troposphere and UTLS
Chemical Coupling of Halogens and Oxygenated Volatile Organic Compounds
Solar Occultation Flux Spectroscopy aboard the Wyoming King Air
The CLOUD experiment: Anthropogenic and Marine Nucleation
Molecular Spectroscopy: weak bands of H₂O and O₂-O₂ collision complexes

The Cosmics Leaving Outdoor Droplets (CLOUD) experiment at CERN, Geneva uses an ultraclean chamber facility to study how gases form new particles (nucleation), and grow to affect cloud formation.
