M.-C. OLIVER CHANG Assistant Research Professor Division of Atmospheric Sciences Full Resume
EDUCATION: Ph.D., Environmental Engineering, University of Southern California, CA M.S., Environmental Engineering, University of Southern California, CA B.S., Geophysics, National Central University, Taiwan

PROFESSIONAL INTERESTS: Dr. Chang's interests include characterizing physical and chemical properties (such as transformation, morphology, and transportation) of ultrafine (<0.1µm) and accumulation mode (0.1-2.5µm) particles in ambient air and source emissions, characterizing source emission profiles for source apportionment. Currently, Dr. Chang is active in several on-going air quality studies, including carbon source apportionment studies in Las Vegas Valley, Southern Nevada Air Quality Study (SNAQS), on-road vehicle emission and residential wood combustion emissions in Lake Tahoe, and SERDP off-road diesel emissions. In addition, Dr. Chang participates in development of DRI carbon thermal/optical analysis laboratory in Las Vegas. Before joining DRI, Dr. Chang was at General Electric Energy and Environmental Research Corporation, where he investigated formation mechanisms and physicochemical properties of accumulation mode and ultrafine particle in exhaust plumes from stationary power generation sources, designed a compact dilution sampler for sampling condensable air pollutants, evaluation of continuous emission monitors, and characterizing emission profile and emission rates of air pollutants from stationary combustion sources. Dr. Chang was the liaison of the Dutch National Research Institute of the Public Health and the Environment (RIVM, the Dutch EPA) and the Southern California Particle Center and Supersite (SCPCS), during his appointment at University of Southern California. Dr. Chang had supervised Dr. Chang's work include: development of coarse, fine and ultrafine particle concentrator for PM adverse health in-vitro and in-vivo studies; investigate indoor-outdoor relationship of coarse and fine particles in the Coachella Valley; develop the particle bounce free Personal Particle Sampler and High Capacity Particle Size Classifier; characterizing volatilization losses of semi-volatile particulate matter; development of air pollution control technology with electrostatic enhancement of stainless steel fiber filters to capture PM emission with high capacity.
