Dr. Callahan is a California transplant who lives in Davis. Originally from New Jersey, she has studied psychology for over 15 years. She researched topics such as the psychological effect of group property and symbols, group perception, persuasion, construal level theory, and retrieval-induced forgetting. She has also taken part in meta-analyses and large-scale replication projects. She has taught at UC Davis and other schools in the area, but Seawolves are by far her favorite students!
