Ph.D. student Jeffrey Cullen is a PhD candidate in the Wilde Lab. Cullen completed his bachelor’s degree at the University of California, Santa Cruz, in marine biology before working for the U.S. Fish and Wildlife Service in Lodi, California, as a biological science technician on the Delta Juvenile Fish Monitoring Program. He earned his master’s degree at the University of Georgia while studying intraspecies interactions and their effects on the use of space in the drift-feeding fish, dolly varden (Salvelinus malma). His Ph.D. work is focused on the trophic distribution of aetokthonotoxin in fishes in a freshwater reservoir in Georgia. This work involves developing methods for toxin extraction and quantification in collaboration with the Environmental Protection Agency as well as the Stable Isotope Ecology Lab at UGA.
