Research Professor
Division of Atmospheric Sciences

Full Resume

Dr. Moosmüller's interests include experimental and theoretical research in optical spectroscopy as well as its applications to atmospheric and aerosol physics.  Currently, 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 both for ambient air monitoring and for vehicle, fugitive dust, and biomass burning emission studies.  His latest research interest is 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 and the Max Planck Institute for Quantum Optics in Garching focused on laser remote sensing.
