Research Interests

Rainer’s general interest is the study of atmospheric chemistry in air quality and climate science, using a combination of in-situ and remote sensing measurement techniques, which he and his group are developing and deploying in polluted urban and pristine atmospheric environments from ships, research aircrafts, and autonomous ground-based networks, and in simulation chamber experiments to develop and test the mechanistic understanding represented in atmospheric models used to manage air resources and climate.

Current Research

Ocean-Atmosphere interactions over the Tropical Pacific Ocean (NSF-SGER); Coastal Halogen Atmospheric Research of Mercury Depletion (EPRI Technology Innovation); Remote Sensing of ozone and secondary organic aerosol precursor gases (NSF-CAREER); Development of Optical Spectroscopic Instrumentation for use in field and laboratory studies; Numerical Modeling of fast photochemical processes of relevance to Air Quality
