Research Abstract |
My research program is centered on space-based climate measurements with particular attention to cryospheric and high latitude regional studies. I am interested in studying processes of global change using various remote sensing techniques, as well as lithospheric properties and loading processes on geological timescales. The research work combines satellite remote sensing techniques, ground observations and numerical modeling to determine how the Greenland and Antarctica ice sheets and the high latitude regions respond to climate worming. This is a very exciting time to be involved in those studies as both the ice sheets and the arctic are very sensitive to climate change and the advent of satellites has provide us with the ability of observing those regions with unprecedent spatial and temporal accuracy. One of the focuses of my research is to develop methods for joint estimation of, or inversion for, different components of the water cycle including its atmospheric and cryospheric components. |
