Cleotilde (Coty) Gonzalez

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.

Palvi Aggarwal, Ph.D.

Post-Doctoral Fellow

Palvi Aggarwal completed her Ph.D. in the area of cyber security at the Indian Institute of Technology, Mandi, India. Prior to IIT Mandi, she did Master's in Information Security and Bachelor’s degree in Computer Science. She is interested in the analysis of cognitive limitations of memory and recall for hackers and analysts and explore experiential decisions made by hackers and analysts in cyber-security games involving deception. Her areas of interest also include Intrusion Detection Systems, and malware analysis using machine learning and deep learning techniques.

Cristobal De La Maza Guzman, Ph.D.

Post-Doctoral Fellow

Cristobal was a Ph.D. student at the Department of Engineering and Public Policy here at Carnegie Mellon University. He graduated from Pontificia Universidad Catolica de Chile in Santiago, Chile with a Bachelor's in civil industrial engineering. He previously worked for the Chilean Ministry for the Environment as both the head of their Department of Environmental Economics and the Division of Information and Environmental Economics. His research has focused on air quality, water rights, and green industries in Chile.

David Hagmann

Ph.D. Student

David is a doctoral student in the Department of Social and Decision Sciences at Carnegie Mellon University, where he is advised by George Loewenstein. David's areas of interest include information avoidance, decisions under risk and uncertainty, intertemporal choice, pro-social behavior, and behavioral interventions (nudges). More broadly, he studies and conducts research in behavioral, experimental, and computational economics. David is particularly interested in how these fields can enrich one another and contribute to public policy.

David came to the United States from Switzerland in 2009 to pursue his undergraduate degree at Fordham University . He graduated from there summa cum laude with a major in Mathematics and Economics and a minor in Psychology. During his time in New York, he was a visiting student at Columbia and at New York University. He also spent a summer at the London School of Economics in the UK.

Erin McCormick

Ph.D. Student

Erin is currently a doctoral student in the Department of Social and Decision Sciences at Carnegie Mellon University. She has interests in basic research about judgment, decision-making, problem-solving, and emotion, as well as applied work on behavior during emergencies.

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.

Qiao profile picture

Qiao Shen

Research Assistant

Qiao is currently a sophomore double majoring in Economics and Statistics, and Psychology at Carnegie Mellon University. She is interested in Behavioral Economics and anything about interactions between people. More specifically, she is interested in studying about the motives of certain actions, environment’s influence on people’s decision making process and how people’s behavior can be predicted and even so some extent manipulated.

Don profile picture

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.
