Dr. Ronaldo Vigo is an associate professor of mathematical and computational cognitive science at Ohio University, where he also directs his SCOPE Lab (Structure, Concepts, and Perception Laboratory). He earned his doctoral degree from Indiana University at Bloomington. His work focuses on the development of context-sensitive mathematical and computational models of cognitive phenomena. He has developed over a dozen such models (most with few or no free parameters) as well as original mathematical theories and frameworks for the study of cognition in general based on symmetry and invariance principles. He is also the author of the scholarly book titled “Mathematical Principles of Human Conceptual Behavior: The Structural Nature of Conceptual Representation and Processing”.
