      GAI YIJUN 蓋怡君

      PhD Student (Admitted in 2021 – 2022)
      Field Area: Humanities and Social Sciences

      Overview

      Before starting the PhD Program at the University of Hong Kong (with the Southern University of Science and Technology), Yijun received her bachelor’s and master’s degree in environmental engineering at the University of Toronto, during which she conducted life cycle assessment on renewable energy systems to evaluate their impacts on air quality, climate change, and human health.

      After receiving her master’s degree, she worked for environmental NGOs to enhance air quality and climate policies. In the meantime, she has developed an interest to find the root cause of environmental issues and how people have been involved in creating and addressing those issues.

      Therefore, her tentative PhD project is a case study on renewable energy systems to explore its history of development and its role in establishing an ecological civilization. This will be an interdisciplinary study involving sociology, history, political science, environmental philosophy, environmental ethics, environmental engineering, etc.
