Research Interests
We study the sources and fate of atmospheric particles which
affect human health, the global energy budget, and the transfer of
materials in the environment. Our focus is on the transport of these
particles across the air-surface interface, for example deposition of
particles to forests and formation of particles from sea foam. We use
aerosol mass spectrometry and other techniques to measure interfacial
transport in the laboratory and the environment. Our goal is to
evaluate and improve the parameterizations which express our
understanding of aerosol interfacial transport in models of the urban
and global atmosphere. We also study sources of particles in the
urban atmosphere, aerosol particle sampling, and statistical analysis
of large aerosol data sets.
