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.

Tyler Malloy, Ph.D.
Post-Doctoral Fellow
Tyler Malloy is a post-doctoral researcher with the DDM lab. He received his PhD in Cognitive Science in 2022 at Rensselaer Polytechnic Institute in Troy, New York. His research interests include cognitive modeling of human perception, learning, and decision making. During his time at RPI, Tyler was a part of the IBM Artificial Intelligence Research Collaboration where he worked alongside IBM researchers on human-inspired reinforcement learning. As a member of the Dynamic Decision Making Lab, Tyler will explore how humans quickly learn new tasks in contexts like cybersecurity that require decision making under risk and uncertainty.

Maria Ferreira, Ph.D.
Post-Doctoral Fellow
Maria José Rodrigues Ferreira earned her Ph.D in Computer Science and Engineering in 2023 from Instituto Superior Técnico, University of Lisbon (Portugal). Her research focuses on enhancing Social Agents' capabilities to assist people in a more personalized and engaging manner by exploring the intersection of Human-Agent Interaction and technology. Specifically, her work involved user-adapted environments, decision making, and the manipulation of personality traits and biodiversity knowledge.

Roderick Seow, Ph.D.
Post-Doctoral Fellow
Roderick Seow received his Ph.D. in Cognitive Neuroscience in 2023 at Carnegie Mellon University. He is broadly interested in learning, generalization, and decision making, and has investigated these topics in the contexts of complex perceptual-motor skills and function learning. As a postdoctoral researcher with the Dynamic Decision Making Lab, he will explore topics surrounding human-AI collaboration such as extending existing cognitive models of individual decision making to collaborative multi-agent contexts.

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.

Duncan Wood
Ph.D. Student
Duncan is a Ph.D. student in the Department of Social and Decision Sciences pursuing the Cognitive Decision Science track. The functional structure of memory, social information integration, social instance learning, and instance simulation are components of his research interests. He got his Bachelor's degree in Cognitive Science and Economics from University–New Brunswick. At Rutgers, Duncan used computational modeling, empirical analysis, and machine learning to research various topics, including friendship homophily, minorities' internet use, and dynamic pricing in costly search markets.

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.
