Ran Zhao leads an active research group in the Department of Chemistry at the University of Alberta, focusing on atmospheric chemistry and its intersection with environmental health. The Zhao Research Group employs a multidisciplinary approach combining laboratory experiments, ambient measurements, and computer simulations to investigate critical air quality issues. Research priorities include: Atmospheric aerosol formation and evolution Indoor air quality monitoring using innovative low-cost sensors Chemical partitioning of pollutants in indoor environments Third-hand exposure pathways from nicotine delivery systems Emissions from solid fuel combustion sources Recent publications demonstrate significant contributions to understanding formaldehyde emissions from entertainment fog machines, brown carbon behavior in Himalayan regions, and microbial volatile organic compounds in indoor settings. The group's work on cow dung burning emissions has provided crucial data for developing regions where this fuel source is prevalent. Their research on iodometry matrix effects has important implications for analytical chemistry methodologies. Dr. Zhao mentors a diverse team of graduate students and research associates, with Jessica completing the first MSc degree in the group in January 2021. Current members include Timothy, Shuang, Vikram, Tania, Max, and several undergraduate researchers who contribute to ongoing projects. The group has secured funding through the University of Alberta's Campus Sustainability Grant and maintains strong collaborations with institutions like SUSTech. Notable research impacts include media coverage of the humidifier study by Global News and CTV News, demonstrating the group's commitment to translating scientific findings for public benefit. The laboratory regularly hosts visitors including university leadership, showcasing the group's prominence within the institution.
