Joey (Zhou) Zang (he/him) is a dedicated PhD student under the guidance of Dr. Jane Liu within the Department of Geography and Planning at the University of Toronto. His journey with the Ge-iSEE lab began as a student research assistant, where he played a pivotal role in the department of advanced geospatial models aimed at enhancing the measurement of air pollution and meteorological factors. This work holds significant importance, as it lays the foundation for robust data and establishes an accessible repository crucial for a wide range of environmental epidemiological studies.
Joey’s doctoral research is centered around the long-term tropospheric ozone climatology on a global scale. To tackle this intricate topic, he employs a multitude of innovative techniques, including remote sensing, modeling and statistical approaches. Through these methodologies, Joey endeavors to unravel the trends in tropospheric ozone and understand how it is impacted by climate change. Read more about Joey’s work on Google Scholar page.
