Katherine graduated with a B.S. in Tropical Biology and Natural Resources Management from the Universidad Nacional de Costa Rica in 2021. She began the M.S. program at John Carroll in Fall 2022, and will study chemical defenses, color, and behavior in the green and black dendrobatid poison frog, Dendrobates auratus, in Costa Rica.
