Gene is interested in all aspects of the ecology, evolution, and management of freshwater fishes. His current research includes studies of: (1) abiotic regulation of habitat use, reproductive ecology, and interannual variation in prairie stream fish assemblages; (2) development and application of quantitative models relating population dynamics of prairie stream fish assemblages to stream discharge; (3) development of models to explain fish movement in telemetry studies and after release in fishing tournaments; and (4) development of models for understanding and assessing the effects of catch-and-release angling. Gene is working on a book on catch-and-release angling.
