Abstract

Nanoparticles and droplets are important condensed phase constituents of our atmosphere, which provide surfaces on which multiphase transformations occur. These transformations in turn drive larger scale impacts on human health and climate. Developing a predictive molecular description of the role that interfacial chemistry plays in both the multiphase oxidation of organic aerosol and cloud droplet nucleation remains an outstanding challenge. I will highlight our efforts to use nanoparticles and droplets in the laboratory to understand heterogeneous reaction mechanisms and the underlying physical chemistry of cloud droplet formation.

Kevin Wilson Kevin Wilson earned a B.A. from Willamette University, a M.A. from St. John’s College (Santa Fe) and a Ph.D. from the University of California, Berkeley. After a postdoctoral fellowship at Los Alamos National Laboratory, he accepted a staff position at LBNL in 2004. Currently, he is the Deputy Director for Science for the Chemical Sciences Division. The Wilson group uses novel mass spectrometric methods and synchrotron based techniques to study organic aerosol oxidation reactions as well as the chemistry occurring at liquid water surfaces.
