Mississippi State, MS 39762

Dr. John Mylroie is Professor Emeritus of Geology at Mississippi State University, having retired in December of 2014. He remains active in the profession, conducting field work in numerous international settings, publishing his results, and teaching field courses for MSU and for other institutions (e.g. University of Bergen, Norway; Leon Levy Native Plant Preserve National Park, Eleuthera, Bahamas). After 8 years at Murray State University, he came to Mississippi State in 1985 to be Department Head, charged by the Dean to revitalize a moribund program. He initiated a field program at the Gerace Research Centre on San Salvador Island, Bahamas, recruited graduate students from across the United States, and increased research expectations and support for faculty. His research areas are caves and karst (landscapes formed by bedrock dissolution), Quaternary carbonate geology, and resource management.  He is founding president of the Karst Waters Institute, a research and outreach facility designed to increase the quality of karst research, and promote its utility to society.  He has over 260 journal publications, field guides and books, and over 300 professional presentations. He graduated 56 MSc students and 4 PhD students (the PhD program began in 2009), and taught over 15 different courses, from introductory to graduate.  With his wife and colleague, Joan Mylroie (retired Instructor of Geography at MSU), he continues to pursue island cave development in archipelagoes across the world.
