Dr. Kwok’s interests include the mass and energy balance of the Arctic and Southern Ocean ice covers and the role of the sea ice in global climate. His work has focused on the analysis of sea ice thickness, small-scale sea ice kinematics, circulation and time-varying gravity over the polar oceans from various spaceborne and airborne instruments. He is a currently a member of the ICESat-2 science team and has served on the science teams of NASA’s ICESat, IceBridge, NASA-ISRO SAR (NISAR), and Surface Water and Ocean Topography (SWOT) missions.
