**DIRECT-STEM program funded by NASA, including research training and summer internship with stipends. Any interested Graduate or Undergraduate students please contact me through emails** 



Dr. Li teaches GEOL 1580 Natural Disasters, GEOG 2820 Spatial Measurement and Elementary Statistics, GEOG 3690 Fundamentals of Geographic Information Systems, GEOG 4820 Multivariate Statistics in Geography, GEOG/GEOL 5210 Advanced Watershed Modeling, and GEOG/GEOL 5220 Hydrologic Remote Sensing. She teaches various softwares and technical computing languages including ArcGIS, MATLAB, R and Hydrologic Modeling System (HEC-HMS) in different classes.



Dr. Li's research interests focus on bridging Water Resources/Hydrology and Remote Sensing to improve the understanding of hydrologic variables. She is interested in the application of satellite data, Geographic Information System(GIS), and information technologies in hydrology and water resources. Her current research activities focus on the utilization of remote sensing data to study the hydrologic responses of watersheds and soil moisture-precipitation interaction, and to evaluate the spatial variability of precipitation using geostatistical and image processing techniques. Current research projects include:

  • Evaluation of Satellite-based Precipitation Estimations 

Funded by NASA Data Intensive Research and Education Center in Science, Technology, Engineering and Math (DIRECT-STEM) 

The NASA DIRECT-STEM is recruiting both undergraduate and graduate students with paid stipend, Jet Propulsion Laboratory (JPL) summer internship and University of California at Irvine (UCI) internship opportunities.

         Collaborator: Dr. Kuo-lin Hsu and Dr. Soroosh Sorooshian at University of California Irvine

  • Interaction between Soil Moisture and Precipitation

         Collaborator: Dr. JT Reager at Jet Propulsion Laboratory (JPL)

  • Change Detections of Mangrove and Coral Reef Ecosystem using Remote Sensing Data
