Curriculum Vitae:

Brian Drouin
Group Supervisor

Dr. Brian Drouin's background in chemistry and mathematics, and interest in molecular structure and symmetry, have fostered a career molecular spectroscopy to support remote sensing observations. Beginning with microwave spectroscopy of organometallic compounds, his Ph. D. work involved measurement and analyses of highly precise rotational transition frequencies of molecules in cold molecular beams. At JPL he has recorded and analyzed millimeter and submillimeter spectra of both astrophysical and atmospheric molecules while incorporating state-of-the-art hardware and software novel spectrometers. He is now a JPL research scientist and is responsible for measurements of molecular line-shape parameters for the Microwave Limb Sounder, as well as measurements of collision rates for water at very low temperatures, and THz measurements of molecules that are expected to be observable with the Herschel Space Observatory. He is the primary caretaker for the JPL spectral line catalog used throughout the spectroscopy and remote sensing communities. He is also the Deputy Principle Investigator for the Polar Radiant Energy in the Far-InfraRed Experiment (PREFIRE) that will quantify the radiative processes effected by changing temperatures in the Arctic.
