James (Jim) Smith, Ph.D., is a scientist and head of the Ultrafine Aerosols Research Group at the Atmospheric Chemistry Division of the National Center for Atmospheric Research (NCAR), and he is currently visiting professor of aerosol physics at the University of Eastern Finland. Dr. Smith received his Ph.D. degree in environmental science and engineering at the California Institute of Technology. His thesis research included one of the first applications of molecular modeling to the elucidation of the photo-oxidation of tropospheric pollutants, as well as in situ measurements of the evolution of the size and charge of highly charged droplets emitted from electrosprayed solutions. Dr. Smith’s work at NCAR involves performing laboratory and field measurements in order to understand and quantify the mechanisms of atmospheric nanoparticle formation and growth. This research is important because the formation of nanoparticles by nucleation and their subsequent growth are poorly understood processes that have significant implications for human health and climate. Dr. Smith’s accomplishments include the development of the Thermal Desorption Chemical Ionization Mass Spectrometer (TDCIMS), which 10 years after its introduction remains the only instrument that can measure the molecular composition of 6- to 30-nm-diameter particles at ambient levels.
