On July 17, 2025, a delegation led by Academician Jinren Ni, Professor from the College of Environmental Science and Engineering at Peking University, visited the Macau University of Science and Technology (MUST). The delegation were warmly welcomed by the Chair Prof. Joseph Hun-wei Lee, Vice-Chancellor and President; Dr. Ka Lok Tong, Vice President; Prof. Yibing Ma, Head of the Department of Environmental Science and Engineering at the Faculty of Innovation Engineering; Prof. Chengkun Liu, Director of The Institute for Sustainable Development; Prof. Zhaoyin Wang, Distinguished Guest Professor from the Department of Environmental Science and Engineering; Associate Prof. Qingbin Song, Program Director; Assistant Prof. Qun Wang and Kai Zhang; Ms. Oi Mei Chu, Head of Academic Affairs Office and Officer of Academic Office of Department of General Education, and Dr. Peng Liu, Research Associate from the Key Laboratory of River Basin Digital Twinning of Ministry of Water Resources.
To promote academic exchange and knowledge sharing, further enhance the understanding and depth of knowledge among faculty and students, the Department of Environmental Science and Engineering of the Faculty of Innovation Engineering organised a thematic lecture and academic seminar on the morning of Academician Jinren Ni 's visit. The lecture was chaired by Prof. Yibing Ma, with Academician Ni giving a presentation titled "Environmental Risks and Ecological Fallacies," delving into current controversies. Special attention was given to the reasoning biases introduced by the fallacy of Pan-Ecology. Using the example of iodine in groundwater and its forms in relation to thyroid disease risk, Academician Ni provided a detailed analysis of different chemical species (e.g., I-, IO3-, and OI) affect ecological and health risk assessments. He systematically analyzed the impact of key processes such as Occurrence, Ingestion, Metabolism, and Disease on risk assessment. Academician Ni emphasized the importance of comprehensively considering the contributions of each process to improve the accuracy of health risk assessments.
President Lee presented a commemorative gift to Academician Ni
In the afternoon, Academician Ni and his delegation visited MUST History and Achievements Exhibition Hall, the State Key Laboratory of Lunar and Planetary Sciences, the State Key Laboratory of Quality Research in Chinese Medicine, and the National Observation and Research Station of Coastal Ecological Environments in Macao. They gained a comprehensive understanding of the development of MUST and learned about the research achievements and ongoing work in the university's key disciplines.
