Tianjin University Delegation Visits Baptist University’s Department of Geography for Academic Exchange
September 3, 2025
Professor Wu Yu of Tianjin University led a group of undergraduate students to the Department of Geography at Hong Kong Baptist University (HKBU) for an academic exchange with faculty and students. The visit aimed to deepen inter-university collaboration and expose students to current frontiers in atmospheric and geographical research.
Opening the session, Prof. Wu introduced Tianjin University’s history and faculty strengths before presenting his recent work on the radiative effects of aerosols. He highlighted a key limitation in many current aerosol–radiation models, which often assume homogeneous particles and overlook the influence of particle morphology. Focusing on black carbon aerosols, Prof. Wu described how morphological evolution during aging alters radiative properties and shared a parameterization scheme that represents morphology across different aging stages, thereby improving the realism of aerosol radiative characteristics in models.
The exchange also featured an introduction to HKBU’s Department of Geography by Han Yuyang, a PhD student supervised by Professor Gao Meng. Han outlined the department’s dual strengths in human and physical geography and its wide-ranging research portfolio, including disaster risk assessment, residential patterns, urban spaces, and climate change. The department has a history of more than 40 years, over 10 full-time academic and teaching staff, and organizes more than 10 overseas and local field trips annually.
In addition, the session highlighted some research led by Prof. Gao, including seasonal air-pollution prediction that leverages climate–environment interactions and methodological advances in climate models through improved brown carbon modules.
The visit provided an opportunity for students and researchers from both institutions to exchange ideas on atmospheric sciences and geography, laying the groundwork for future collaboration in research and student engagement.
