Justin has been fascinated by marine mammals since his childhood; adopting a humpback whale named Stub when he was 8, a picture of whom hung above his bed for many years. Through the study of psychology, Justin found a way to combine his love of languages and language with his interest in marine mammal behavior. His doctoral research focused on how echolocation use may be related to a dolphin's ability to comprehend referential signaling - an important building block for complex communication systems and an indispensable component of human language.
