Introduction of Dr. Douglas R. Worsnop:

      Dr. Worsnop is a leading expert in the chemistry and heterogeneous reactions of atmospheric aerosols. He has pioneered the development of laboratory and field measurement techniques for investigating chemical interactions between atmospheric trace gases and aerosols, including water droplets. His expertise extends to the mechanisms of the formation of polar stratospheric clouds, and to measurements of the chemical composition of atmospheric aerosols. Dr. Worsnop is a recipient of the 2004 Benjamin Y. H. Liu Award (American Association for Aerosol Research) for his achievements in atmospheric composition measurement with the Aerodyne aerosol mass spectrometer system (AMS). He received the 2010 Yoram Kaufman (AGU Atmospheric Sciences) for Unselfish Cooperation in Research and is a Fellow of American Association for the Advancement of Science (AAAS), American Geophysical Union (AGU) and the American Association for Aerosol Research (AAAR).
