C. K. Shum

C. K. Shum's research uses satellite-based measurement techniques—such as satellite gravimetry (measuring tiny changes in Earth's gravity field to track mass changes), GPS/GNSS positioning, and radar remote sensing—to study how ice sheets, sea levels, and groundwater are changing over time. Much of the work focuses on Antarctica and Greenland ice loss, global sea level trends, and groundwater depletion in regions like the North China Plain, often combining these geodetic (Earth-measurement) methods with machine learning to improve data analysis. This research is relevant to students interested in climate change monitoring, water resources, and applying remote sensing or computational methods to environmental problems.

Publication output has gradually declined over the past decade, from around 30-34 papers per year in 2017-2018 to an average of about 18 papers per year in the most recent five years, though output has been relatively stable since 2022.
