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.

Nhat Phan
Post-Doctoral Fellow
Nhat received his Ph.D. degree in Applied Mathematics in 2016 at the University of Lorraine, France where he had two-year postdoctoral experience afterward. His research interests include issues related to optimization applied in machine learning and decision making. At the lab, he performs research studies on developing Instance-based Learning models enhanced with reinforcement learning techniques in goal-seeking and collaboration tasks.

Baptiste Prebot, Ph.D.
Post-Doctoral Fellow
Baptiste received his Ph.D. in Cognitive Engineering from the University of Bordeaux, France. His research focused on the real-time evaluation of Team Cognition in military Command and Control using psycho-physiological and behavioral monitoring. As a former UX designer, Baptiste's research interests are oriented towards the teaming of human and autonomous AI's in complex systems and how to facilitate the use of technology to optimise the performance of Human-Autonomous AI teams.

Erin Bugbee
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.

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.

Angela Zhu
Undergraduate Research Assistant
Angela is a senior undergraduate student pursuing a B.S. in Economics & Statistics at Carnegie Mellon University. She is interested in understanding and applying the modeling approach towards cognitive science, under the framework of Dynamic IBL models. She will work on projects involving Stackelberg Security Games (SSG) implemented in two levels decisions in a simple Attacker-Defender setting called the "Box Game".
