My name is Yingjie Hu. I am an Assistant Professor of the Department of Geography at the University of Tennessee, Knoxville (UTK), USA. My main research area is Geographic Information Science (GIScience) and more specifically Geospatial Semantics. I study the space, time, and semantics of geographic information, as well as the interactions among the three. My research aims to bring a semantic perspective which enables intelligent systems to automatically understand geographic information and which helps explain spatiotemporal patterns of geographic phenomena. I run the Geospatial Semantics and Data Analytics (GSDA) Lab at UTK, which focuses on projects related to spatial and text data mining, information value measurement, and spatial data infrastructures. Previously, I received my PhD from the Department of Geography at the University of California, Santa Barbara (UCSB), and I was a member of the Space and Time Knowledge Organization (STKO) Lab. I was also a research engineer during summers at the Applications Prototype Lab in Esri Inc., where I designed and developed prototypes for the next generation's GIS.
