Program: National Marine Fisheries Service – Sea Grant Joint Graduate Fellowship Program in Population Dynamics


Katelyn Bosley was awarded three years of fellowship support with a National Marine Fisheries Service (NMFS) Sea Grant Joint Graduate Fellowship Program in Population Dynamics.

Katelyn's advisor is Dr. Brett Dumbauld (USDA-ARS), and her mentor is Dr. Thomas Wainwright with the Northwest Fisheries Science Center, Fish Ecology Division in Newport, Oregon. With her advisor, Katelyn is developing an age-based population model for burrowing shrimp using the novel lipofuscin aging method.


Katelyn holds Bachelor degrees in Biology and Marine Biology from College of Charleston in Charleston, South Carolina (2002). In 2008 she completed her M.S. degree in Fisheries Science at Oregon State University in the Department of Fisheries and Wildlife and the title of her thesis was "Use of Extractable Lipofuscin as an Age Biomarker to Determine Age Structure of Ghost Shrimp (Neotrypaea californiensis) Populations in West Coast Estuaries". For her Masters' work, Katelyn developed a method of age determination for burrowing shrimp using the fluorescent age pigment, lipofuscin, which is found in animal neural tissues.

Professional and Research Interests:

Her current work towards a PhD in Fisheries Science at Oregon State University is focused on studying population ecology of burrowing thalassinidean shrimp in west coast estuaries. Using manipulative field and laboratory experiments, Katelyn is investigating the effects of temperate and food on growth and aging rate, and will further validate lipofuscin as an accurate aging method. Burrowing shrimp are important components of the estuarine ecosystem and provide a number of essential functions in their role as ecosystem engineers. Much attention has been drawn to the two most common species, Neotrypaea californiensis and Upogebia pugettensis, as population monitoring has shown significant declines in both. Using lipofuscin as an aging method Katelyn aims to improve accuracy in population dynamics models which may be applied to conservation and management of crustacean populations.

Katelyn lives on the Oregon Coast where she enjoys cooking, gardening, being outdoors and spending time with her husband and two young daughters, Stella and Eveline.
