Yao-Yi Chiang, Ph.D., is an Associate Professor (Research) of Spatial Sciences in the Spatial Sciences Institute at the University of Southern California Dornsife College of Letters, Arts and Sciences and Associate Director of the Data Science Institute, University of Southern California Viterbi School of Engineering.
His general area of research is artificial intelligence and data science, with a focus on information integration and spatial data analytics. He develops computer algorithms and applications that discover, collect, fuse, and analyze data from heterogeneous sources to solve real-world problems. Chiang is an expert in digital map processing, pattern recognition, and geospatial information systems (GIS). In addition, he teaches data mining, spatial databases, and mobile GIS.
He has published many articles on automatic techniques for geospatial data extraction and integration. For his paper Querying Historical Maps as a Unified, Structured, and Linked Spatiotemporal Source, he won the first place prize at the Computing Community Consortium (CCC) sponsored Blue Sky Ideas Track Competition at the ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems 2015 (SIGSPATIAL 2015) in Seattle, Washington. The institutions funding his research include the National Science Foundation, Defense Advanced Research Projects Agency, and the National Endowment for the Humanities.
Prior to USC, Chiang worked as a research scientist for Geosemble Technologies (now TerraGo Technologies), which was founded based on a patent, of which he was a co-inventor, on geospatial data fusion techniques.
