Dr.Cheol-Heon Jeong is currently a senior research associate at the Southern Ontario Centre for Atmospheric Aerosol Research (SOCAAR) in University of Toronto.Cheol-Heon received his Ph.D. degree in Dept. of Environment Engineering at Clarkson University, NY, USA with a dissertation on ultrafine particle number size distributions in Rochester: implication for nucleation events and application of advanced receptor modeling.
His research is focus on the measurement of physical and chemical properties of submicron aerosol particles in the atmosphere. He is working on the characterization of ultrafine particles number concentrations measured by the Scanning Mobility Particle Sizer (SMPS) and the Fast Mobility Particle Sizer (FMPS) to identify the sources of ultrafine particles as well as their spatial and temporal distributions. He is involved in the study of the identification of PM2.5 sources and their contributions in five cities across Canada using Positive Matrix Factorization (PMF) incorporating gaseous pollutants and meteorological parameters. He is particularly interested in quantification of chemical compositions using the Aerosol Time-of-Flight Mass Spectrometry (ATOFMS) and determination of the source of individual particles based on ATOFMS mass spectral signatures.
