Thank you for visiting my website! I am Donald R. Gaffney, but I often go by Ryan. As a Senior Researcher at the Owen Graduate School of Management, my work often focuses on the role of uncertainty in consumer inference. I am particularly interested in examining how various types of uncertainty (e.g., aleatory and epistemic) influence behavior and consumption patterns. This theme extends both my dissertation and ongoing studies as I seek to deepen our understanding of these complex but powerful relationships. Anchored in the field of judgment and decision-making, my research also intersects with areas such as artificial intelligence, branding, bias, and public policy.
