He studied in Wuhan University for his bachelor degree and got his PhD in Geophysics from the University of Colorado. Before joining CUHK, he was a George Thompson Postdoc Fellow at the Stanford University. His study applies a wide range of geophysical and remote sensing techniques to the Earth’s complex cryospheric systems including permafrost and glaciers, aiming to quantify and understand their significant changes in a warming climate. He has conducted several pioneer studies of using space-borne radar interferometry to investigate permafrost and active layer dynamics in the Arctic.
