Dr. Middlebrook is a Research Chemist at the NOAA Chemical Sciences Laboratory (CSL) in Boulder, Colorado. She joined the Laboratory in 1994 as a Department of Energy Distinguished Postdoctoral Research Fellow in Global Change after receiving degrees in chemistry from the University of California at Berkeley and Stanford University. Her principle research interest is the chemical measurement of atmospheric aerosols to advance the understanding of their formation, chemical transformations and transport in the atmosphere, and the impact of these aerosols on air quality and climate. She has participated in several NOAA ground-based and airborne field programs using a Compact Time-of-Flight Aerosol Mass Spectrometer with light scattering (LS-C-ToF AMS). Her AMS calibration work on the effect of particle phase on the composition-dependent collection efficiency has been parameterized and is used for post-processing all AMS data.
1994: PhD Physical Chemistry, Stanford University
1986: BS Chemistry, cum laude, University of California, Berkeley
Aerosol Composition and Formation: In-situ observations of aerosol chemical composition primarily with the c-ToF AMS with the light-scattering module, aerosol emission and secondary formation downwind of various sources, and phase-partitioning between trace gases and aerosols.
Heterogeneous Chemistry: Study of reactions occurring inside or at the surface of aerosols and their potential impact on air quality and climate.
Aerosol Instrumentation: Development and application of new techniques for precise, fast-time response atmospheric aerosol chemical composition measurements.
