Biography

Tim took over as leader of the Hawai'i Unit in 2016 after serving as the Assistant Unit Leader-Fisheries at the Texas Unit (2010-2016). He is an adjunct associate professor in the Department of Marine Science at the University of Hawai'i-Hilo.

Research Interests

Tim's research is focused 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.

Teaching Interests

Tim teaches courses in ichthyology, fish ecology and physiology, marine ecology, and fisheries and climate change.
