Biographical Sketch

Yao-Yi Chiang, Ph.D., is an Assistant Professor (Research) in Spatial Sciences in the Spatial Sciences Institute, University of Southern California (USC). He is also a Visiting Computer Scientist at the USC Information Sciences Institute. Dr. Chiang received his Master and Ph.D. degrees in Computer Science from the University of Southern California in 2004 and 2010, respectively; his Bachelor degree in Information Management from the National Taiwan University in 2000. His general area of research is information integration, with a focus on discovery, extraction, and fusion of geospatial data from heterogeneous sources. In particular, Dr. Chiang is an expert in digital map processing, pattern recognition, and geospatial information system (GIS). He teaches spatial databases and GIS programing. He has published many articles on automatic techniques for geospatial data extraction and integration. Prior to USC, Dr. Chiang worked as a research scientist for Geosemble Technologies (now TerraGo Technologies), which was founded based on a patent on geospatial-data fusion techniques and he was a co-inventor.
