Research Interests

Dr. Liu's research field includes remote sensing, GIS, the integration of remote sensing and GIS, and urban environmental change. She has worked in the United States on diverse research projects including such topics as urban heat island, human-environment interactions, and environmental health. Dr. Liu was the recipient of 2007 Benjamin Moulton scholarship at Indiana State University, and the recipient of 2006 Outstanding Research Graduate Student at the Department of Geography, Geology, and Anthropology, Indiana State University. She also received Outstanding Leadership & Service Award twice in 2004 and 2005 at Indiana State University.

Dr. Liu is currently working with Professor Tal Ezer at Oceanography department on a project, Analysis of Remote Sensing Data to Improve Mapping and Prediction of Tidal Flooded Regions in Cook Inlet, Alaska. She is a member of American Society for Photogrammetry and Remote Sensing and a member of Association of American Geographers.
