Research and Teaching Summary
Susan Bridges was a faculty member in the Department of Computer Science and Engineering for almost 20 years before her retirement. Her research and teaching was in the general areas of artificial intelligence and knowledge discovery. For the last 10 years she has worked primiarily in the areas of computional biology and bioinformatics. She established the Institute of Digital Biology (IDB) at Mississippi State with Dr. Dawn Luthe (now at Penn State) and Dr. Shane Burgess (now at the University of Arizona). The IDB is now part of the Institute for Genomics, Biocomputing, and Biotechnology. She also established the Computational Biology Certificate program at Mississippi State with Dr. John Boyle of the Department of Biochemistry and Molecular Biology.
