Summary: Dr. Sillman develops and applies models for atmospheric chemistry and transport in polluted regions of the atmosphere.
These models are usually 3-dimensional representations of the lower atmosphere, including the following:
Dr. Sillman's major research specialization has been tropospheric ozone (Click here for overview). His research has helped to identify the emission sources that lead to ozone formation in polluted regions. He has also developed innovative methods for evaluating the accuracy of models in comparison with measurements - a topic also known as observation-based methods (click here for details).
Dr. Sillman has also developed models for global-scale atmospheric chemistry in collaboration with other faculty members at the University of Michigan (see Global chemistry and climate modeling group ). He also participates in PROPHET , an interdisciplinary research program at the University of Michigan Biological Testing Station.
Dr. Sillman and Dr. Joyce Penner at Michigan participated in a research project to model the formation of Perfluorocarboxylic acids (PFCAs) at the global scale. This confirmed the theories of Tim Wallington and Scott Mabury that PFCAs result from the breakdown of fluorotelomer alcohols, an industrial product. PFCAs have been widely observed as environmental contaminants, especially in the arctic. (More information is avaiable here .)
Dr. Sillman has developed extensions of atmospheric models to include representation of mercury, in collaboration with other faculty members at the University of Michigan (see Air Quality Laboratory).
Dr. Sillman works with the Community Model for Air Quality (CMAQ) developed by EPA for use in evaluating air quality in polluted regions in the U.S. Dr. Sillman has also developed his own models, including an improved method for solving the equations of photochemical production and loss.A list of research publications available for download can be found by clicking here.
