Ronaldo Vigo is Associate Professor of Mathematical and Computational Cognitive Science at Ohio University where is also director of the Consortium for the Advancement of Cognitive Science and the SCOPE Lab. He received his doctoral degree in Mathematical and Computational Cognitive Science from Indiana University at Bloomington where he was the recipient of the NIH Mathematical Modeling Training Grant. His core work focuses on the formulation and development of mathematical and computational models of similarity assessment, attention, perception, human generalization (e.g., concept learning & categorization), and choice/decision behavior. In addition, he has been working on the development of alternative methods for dimensionality reduction, feature selection and extraction, and on the development of new machine classification algorithms that are inspired by his mathematical and computational models of human classification behavior. Moreover, he is the author of the scholarly book entitled
