Ada "Ginny" Campbell is a Ph.D. student in marketing at SIU. After earning her bachelor's degree in history with a minor in digital media marketing, she pursued her growing passion for the field, completing both an M.Sc. in Marketing and an MBA.During her graduate studies, Ada's work as a marketing department assistant sparked a deep interest in academia. This was further solidified by her professional experience as a marketing assistant at National Rarities, where she found herself constantly questioning the "why" behind marketing decisions and outcomes, as well as the reasons customers made the choices they did. This curiosity and desire to connect practice with theory led her to join the doctoral program.Ada's research interests center on consumer behavior, branding, and culture.
