Dr. Xiang Gao is currently a research scientist in the Center for Global Change Science at the Massachusetts Institute of Technology. Her primary research interests are to understand the role of the land in shaping weather, climate, hydrology, biogeochemistry, and water resources on local to global scales using powerful methodologies such as supercomputing model simulations and satellite remote sensing. She had conducted the research in a wide range of topics, including the development and application of land-surface models, remote sensing of vegetation biophysical parameters, characterizing climate extremes (heavy precipitation, heat wave) and their responses to shifts in climate regimes, global hydrological cycle, arctic permafrost degradation and associated biogeochemistry impacts, and risk-based water resource assessment. She has actively involved in several national and international projects of different disciplines, including the NASA Earth Observing System (EOS) Moderate Resolution Imaging Spectroradiometer (MODIS), the 2nd Global Soil Wetness Project (GSWP-2), and the NASA Energy and Water Cycle Study (NEWS), and servers as a member of Permafrost Carbon Network. Her recent research focuses on the use of the first satellite-retrieved soil moisture product from Soil Moisture Active Passive (SMAP) mission to refine global land trace gas emissions and their climate feedbacks.
