Weathering of oil following the Deepwater Horizon oil spill
Detailed chemical analysis of gasoline and diesel emissions from domestic vehicles and trucks
The weathering of oil following the Deepwater Horizon (DWH) oil spill has large implications for both the air quality around the site and the final fate of the spilled oil. Using the composition of the DWH oil from GC×GC analysis in the Goldstein group, I am building a detailed model of evaporation (including detailed sea-surface phenomena/turbulence) and subsequent aerosol formation over the oil slick following the spill.
Prior to his work at Berkeley, Dr. Drozd was a Dreyfus Postdoctoral Fellow (2011-2013) at Columbia University under Prof. Faye McNeil. There he studied aerosol properties and chemistry focusing on aqueous aerosol systems including: acid-catalyzed uptake, brown carbon formation, and effects of metal-organic reactions on aerosol CCN activity. While at CMU he worked on a range of projects spanning quantum mechanical calculations, reaction dynamics, and sampling and analysis of gas-turbine engine emissions. His PhD thesis was entitled Ozonolysis Intermediate Dynamics and Hydroperoxide Photodissociation in the Atmosphere. At OSU he worked under Drs. John and Susan Olesik, studying the binding of heavy metals to humic acids.
