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.

Erin McCormick

Ph.D. Student

Erin is a doctoral student in Behavioral Decision Research through the Department of Social and Decision Sciences at Carnegie Mellon University. She received her Bachelor of Science in Statistics and Bachelor of Arts in Behavioral Decision Sciences from Brown University in 2020. Her previous research spans the explore-exploit dilemma, trust in humans versus machines, computational neuroscience, and music information retrieval. She is interested in how we can create computational cognitive models of human learning and decision making, and how knowledge gained from these models can be used to improve both human decisions and artificial intelligence.

In the Dynamic Decision Making Lab, she is currently working on a project about individual judgment and decision making in environments where the probability of an event occurring changes over time. In addition to the change detection project, she has worked on studies about the measurement and mitigation of cognitive biases (for example, the bias blind spot), survey methods to assess risk-taking propensity, and cognitive-loaded based lie detection methods. She received a Bachelor's degree in Psychology from Harvard University in 2010.

Chase McDonald

Ph.D. Student

Chase is a doctoral student in the Social and Decision Sciences department. His research interests include both empirical and simulated multi-agent systems and their connections to social decision-making, cognition, and intelligence. He received his Bachelor’s degree in Computational Social Science from the University of California, Los Angeles, and wrote his undergraduate thesis on the emergence of inter- and intra-group norms under discrimination in multi-agent reinforcement learning systems.

Don Morrison

Senior Research Programmer

Don received his S.B. in Physics from M.I.T., and M.S. in Computer Science from the University of Utah. He works on software supporting researchers in the DDMLab and the Psychology Department's FMS Group. He previously worked in the HCII, and before that a variety of software companies. Outside of work, Don is obsessed with change ringing, an obscure art form that arose in Renaissance England and combines music, sport, and group theory.
