About Me

My name is Yingjie (Jason) Hu. I am an Associate Professor in the Department of Geography at the University at Buffalo (UB), The State University of New York (SUNY). I am also an Adjunct Professor in the Department of Computer Science and Engineering, and an Affiliate Faculty of the Center for Geological and Climate Hazards and the AI and Data Science Institute at UB. My research expertise is in geospatial AI (GeoAI), natural hazards, geographic information science, and disaster management. I lead the GeoAI Lab@UB, a research group focusing on integrating geospatial data, GIS, and AI methods to understand human-environment interactions under disaster contexts and to address disaster-related challenges. The disasters we have studied include wildfires, winter storms, and hurricanes. Because disasters are highly complex, our research is interdisciplinary by nature and we frequently interact and collaborate with researchers from Civil and Environmental Engineering, Earth System Science, Environmental Science, and Computer Science and Engineering. The research of my group contributes to better understandings of disaster-related human-environment interactions and helps build a more resilient and sustainable society.

Prospective Students: If you are interested in working with me, please check this Opportunities page to see whether there is an opening.
