Dr. Gengchen Mai is currently looking for 1-2 graduate students starting in Fall 2025 as well as 1-2 visiting scholars. The admitted graduate students will work closely with Gengchen in the Department of Geography and the Environment, University of Texas at Austin on Geospatial Artificial Intelligence (GeoAI) research. If you are interested in GeoAI, spatially explicit machine learning, deep learning, knowledge graphs, and spatial data mining, you are encouraged to apply. To get a taste of Dr. Mai’s research, you can read some of his publications:
