Cleotilde (Coty) Gonzalez, Ph.D.
Research Professor and Founding Director of the DDMLab
Coty is a Research Professor in the department of Social and Decision Sciences at CMU. She earned a Ph.D. in Management Information Systems from Texas Tech University in 1996.
Coty's research lies at the intersection of Human Behavioral Decision Making and Technology. Her research program is motivated by real-world decision making and by the challenges involved in studying dynamic decision making in the laboratory. Her research is embedded within a theoretical framework that emphasizes the role and development of decisions from experience, the similarity of contexts, and the cognitive abilities of decision makers.
