Hongjie Xie

Hongjie Xie is a professor at the Department of Geological Sciences, University of Texas at San Antonio. His specialty is remote sensing for hydrology and cryosphere studies. In-situ measurements and field experiences are crucial in helping scientists to understand and interpret what we see from the satellite images and to develop and improve algorithms for retrieving geophysical properties of objects imaged from satellite sensors. Since 2006, he and his research team have been traveled (over 10 times) to the three Polar Regions (Arctic, Antarctic, and Tibetan Plateau) for data collections and experiments. His main research focus has been on mapping sea ice, snow cover, glacier lakes and their changes under the warming climate. Since 2010, he has been a co-lead (funded by NASA and U.S. Department of Education) for summer workshops, specifically designed for K-12 educators to gaining knowledge on earth and environmental science/engineering, including the polar science and climate changes.
