Hongjie Xie is a Professor and Graduate Advisor of Record in the Department of Geosciences within the College of Sciences at The University of Texas at San Antonio (UTSA). He leads the Laboratory for Remote Sensing and Geoinformatics (LRSG), a research group actively engaged in polar, climate, hydrological, and planetary remote sensing studies. Institution: The University of Texas at San Antonio School: College of Sciences Department: Department of Geosciences Role: Professor and Graduate Advisor of Record Lab: Laboratory for Remote Sensing and Geoinformatics (LRSG) Education: Ph.D. in Geological Sciences, University of Texas at El Paso M.S. in Geochemistry, Beijing Research Institute of Uranium Geology B.S. in Geology, East China Institute of Technology Research Interests Hongjie Xie's research is centered on polar and climate science , with a strong emphasis on remote sensing and geoinformatics . His work spans multiple critical environmental domains including Arctic and Antarctic sea ice dynamics, water resource assessment in the Tibetan Plateau, surface hydrology (precipitation, snow cover, soil moisture, evapotranspiration), and even remote sensing of Martian surface processes. His research integrates satellite data with field observations to validate geophysical products and develop advanced algorithms for environmental monitoring under climate change. Publications and Research Trends While specific article titles are not listed in the provided text, Dr. Xie's research output focuses on the application of remote sensing to cryospheric and hydrological systems. His work demonstrates a consistent trend in using multi-sensor satellite data, field validation, and modeling to understand climate-driven changes in fragile environments such as the Arctic, Antarctic, and high-altitude regions like the Tibetan Plateau. His interdisciplinary approach bridges geoscience, climate science, and planetary science. Scientific Awards No specific awards are mentioned in the provided material. Advising and Grants Dr. Xie serves as the Graduate Advisor of Record, indicating active mentorship of graduate students. His research is supported by major federal and institutional funding sources, including NASA, NSF, NOAA, ONR, USGS, and the U.S. Department of Education through the Minority Science and Engineering Improvement Program (MSEIP). His participation in the 4th Chinese Arctic Expedition was supported by NOAA's Climate Research/Sea Ice Outlook Program and a NASA grant (#NNX08AQ87G). Laboratories and Research Teams Dr. Xie founded and leads the Laboratory for Remote Sensing and Geoinformatics (LRSG) , established in 2004 at UTSA. The lab conducts fieldwork, including polar expeditions (2010, 2013, 2015), and maintains facilities such as the Pico de Orizaba Spectral Measurement station. The LRSG is also associated with the ASPRS Center for Advanced Measurements in Extreme Environments (CAMEE). The team collaborates internationally, particularly with Chinese scientists, and contributes to global initiatives like the Arctic Sea Ice Outlook program.
