Senior Research Associates
Cheol-Heon Jeong, Ph.D.
Tel: (416) 978-5932
Cheol-Heon Jeong is a senior research associate in Southern Ontario Centre for Atmospheric Aerosol Research (SOCAAR) at the University of Toronto. His research interests primarily involve physicochemical characterization of airborne particles, source identification of air pollution using a combination of advanced instruments and modeling, spatial and temporal variations of traffic-related air pollutants including tailpipe and non-tailpipe emissions, and personal exposure to traffic emissions in indoor and outdoor microenvironments.
Qin Liu, PhD
Dr. Qin Liu is a Senior Research Associate at the Institute for Studies in Transdisciplinary Engineering Education and Practice (ISTEP) of the Faculty of Applied Science & Engineering, University of Toronto. Qin completed the Higher Education program and earned her Ph.D. from the Ontario Institute for Studies in Education, University of Toronto, with a dissertation on the impact of quality assurance processes on curriculum development in Ontario postsecondary education.
Her current research includes the association between student experiences and competency development (particularly students’ educational and career pathways), student data analytics, and evidence-based instructional strategies in the context of engineering education. She supports faculty members and students in conducting engineering education research. She is well versed in qualitative and quantitative methods in education research and experienced in conducting institutional research, program evaluation, impact analysis, and learning outcomes assessment. Her published work can be found at academia.edu.
Kerolyn’s PhD research was an improving land-used based estimation of traffic-related air pollution by extending models over space and time. She is now a Postdoc in the group, in collaboration with the Canadian Urban Environmental Health Research Consortium (CANUE).
Jonathan Wang received his honours B.Sc in Chemistry from Carleton University in Ottawa. During his undergraduate career, he worked at the National Research Council as a research assistant focusing on the determination and characterization of toxic pollutants from burned materials. After graduation, he pursued an M.Sc under the supervision of Professor Jennifer G. Murphy at the University of Toronto in the Department of Chemistry. He worked with an off-axis integrated cavity output spectrometer (OA-ICOS) to measure carbon dioxide and methane exchange between a Central Ontario temperate forest and the atmosphere calculated using the eddy covariance technique. Jon joined SOCAAR in 2012 as a Ph.D. student under the supervision of Professor Greg J. Evans. His research involves the analytical techniques to measure traffic-related pollutants such as ultrafine particles, black carbon, and metals in order to better quantify the direct contribution of vehicles to near-road pollutant levels. This will help link actual human exposure levels near roadways to epidemiological findings to these pollutants. He joined the group as a Postdoc in 2017.
