Biography

Dr. John Schalles is Professor of Biology at Creighton University, former Department Head and Co-Founder and Director of the Environmental Science Program, and an Adjunct Professor of Marine Science at the University of Georgia. He teaches undergraduate and graduate courses in aquatic science, remote sensing, toxicology, and zoology. He has broad interests in aquatic ecosystems, with a primary focus on spatio-temporal patterns of primary production in inland and coastal waters and wetlands. John was born in Pittsburgh, Pennsylvania and lived in Grove City, Pennsylvania, Oxford, Ohio, and Atlanta, Georgia before moving to Omaha in 1979 to accept his current position in the Creighton University Biology Department. He is married to Nancy Edwards Schalles, a recently retired high school teacher. Their two sons, Matthew and James both attended Creighton and earned B.S. degrees. John enjoys music (piano and electronic keyboards, church choir); outdoor hiking, nature photography, and scuba diving; and travel to experience different cultures and natural environments.
