Tim Grabowski, PhD
Unit Leader - Hawaii Cooperative Fish and Wildlife Research Unit
Dr. Grabowski received graduate degrees from Texas A&M University and Clemson University before joining the Texas Unit in 2010. In 2016, he became the Unit Leader of the Hawai'i Unit and serves as faculty at both the University of Hawai'i at Hilo and University of Hawai'i at Mānoa. Dr. Grabowski conducts research on the reproductive and behavioral ecology of fishes, fish growth and early life history, aquatic landscape ecology, and the conservation and management of fishes. His past research has run the gamut from dealing with threatened and endangered riverine fishes to looking at issues related to the sustainability of large-scale commercial fisheries and small-scale recreational fisheries to researching or providing technical assistance on issues related to the allocation of water and public access to natural resources. Dr. Grabowski’s research has spanned across a wide range of taxa, latitudes, and salinities from Atlantic Cod fisheries in Iceland to the conservation of large river fishes in the southeastern and southwestern U.S. His current research focuses on the complex social and ecological interactions that influence to productivity and sustainability of nearshore and reef fisheries in Hawai'i and throughout the Pacific. Dr. Grabowski teaches courses in ichthyology, fish ecology and physiology, marine ecology, and fisheries and climate change.
