David Kazyak, Ph.D.
Dave Kazyak is a Supervisory Research Fish Biologist at the USGS Eastern Ecological Science Center in Kearneysville, WV.
Dave Kazyak is a Supervisory Research Fish Biologist at the USGS Eastern Ecological Science Center leads a conservation genetics and genomics research team. His research applies quantitative approaches in conservation genetics and population dynamics to provide decision-relevant information for imperiled species. Dave 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, including techniques using combinations of acoustic telemetry, side-scan sonar, and genetics.
