Dr. Moosmüller’s interests include experimental and theoretical research in optical spectroscopy as well as its applications to atmospheric, aerosol, and climate physics. His research focuses on development and application of real time, in situ measurement methods for aerosol light absorption, scattering, extinction, and asymmetry parameter, and new optical remote sensing techniques. These measurement methods are being used for ambient air monitoring and vehicle, fugitive dust, and biomass burning emission studies. His latest research interests are fast, ultra-sensitive measurements of elementary mercury concentrations and fluxes and aerosol morphology and its influence on aerosol optical properties with a focus on fractal-like chain aggregates found in combustion particles. Dr. Moosmüller has also participated in the planning, fieldwork, and data analysis of several major air quality studies. During his first three years at DRI, he was responsible for the airborne ozone lidar research program under a cooperative agreement with the USEPA.
Before joining DRI, Dr. Moosmüller was at Colorado State University where he investigated Brillouin light scattering of spin waves and millimeter-wave effective line widths in thin metal films. He also did research on high-spectral-resolution lidar and coherent light scattering techniques. This work included the development of supersonic flow measurement techniques and the investigations of spectral line shapes. His earlier work at the Ludwigs-Maximilians Universität in Munich, Germany and the Max Planck Institute for Quantum Optics in Garching, Germany focused on laser remote sensing.
