Alexis K. H. Lau劉啟漢
Head & Chair Professor
Tang Junyuan Professor of Environmental Science
Geophysical data analysis, atmospheric modelling, regional air pollution, satellite remote sensing, exposure and health, and sustainable urban environments.

People
Chair professors, interdisciplinary educators and early-career researchers — appointed jointly across HKUST so environmental problems are never owned by a single department.
