Tim Grabowski, PhD
Unit Leader - Hawaii Cooperative Fish and Wildlife Research Unit
Research Interests
Tim is interested in the behavioral and physiological ecology of fishes and applying these fields to management and conservation issues. His research tends to focus on the reproductive ecology of fishes as well as local adaptation and population structuring.
Teaching Interests
Tim currently teach field ichthyology and foundations of ecology and conservation biology at Texas Tech University. He also teaches a summer course at the University of Iceland examining the effects of anthropogenic impacts, such as climate change and commercial fisheries, on the marine environment.
