David Kazyak, Ph.D.

Dr. Kazyak is a research ecologist at the USGS Leetown Science Center where he co-directs the Conservation Genetics and Genomics Laboratory.


His research applies quantitative approaches in conservation genetics and population dynamics to provide decision-relevant information for imperiled species. Dr. Kazyak's current projects use cutting-edge genetics tools to identify biologically-appropriate management units, measure rates of gene flow, and characterize how isolation, genetic drift, and hatchery supplementation impact wild populations. He also is working to develop novel approaches to census imperiled fishes and using stochastic simulation models to understand how environmental change may influence population dynamics.
