Our Members

Congratulations to Lelyn Saner, who will be starting his research professorship at the University of Maryland's Center for Advanced Study of Language this fall.

Jolie Martin joins us as a Post-Doctoral Fellow. She completed her Ph.D. in Science, Technology, and Management from a joint program between the Harvard Business School and Computer Science department. Jolie's past research explores various aspects of judgment and decision-making, including preferences for risk in experience, sharing of opinions in social networks, and the impact of interface design on user perceptions.

Tomás Lejarraga will be joining the lab as another Post-Doctoral Fellow this October. Tomás completed his Ph.D. in Economics from the Universitat Pompeu Fabra in Barcelona, Spain; where he was also a part of the Laboratori d'Economia Experimental.

In addition, our lab will also be joined by Michael Yu, a second-year graduate student from the Department of Social and Decision Sciences at Carnegie Mellon, and Ripta Pasay as a part-time research programmer.

Dr. Cleotilde Gonzalez recently spoke to a large group of faculty in computer science, psychology and management at the Wyzsza Szkola Biznesu (National-Louis University) in Nowy Sacz, Poland. She also taught a summer course in Human Factors in her time in Poland.

Both Varun Dutt and Jolie Martin attended the Summer 2009 Institute on Bounded Rationality in Psychology and Economics organized by the Max Planck Institute for Human Development in Berlin, Germany.


New Research

Earlier this year, the Dynamic Decision Making Laboratory partially sponsored the Dynamic Stocks and Flows Model Comparison Challenge. The challenge was open to everyone and invited participants to develop computational models that simulate human performance in the Dynamic Stock and Flow task in a variety of conditions. The top three model developers (Reitter, Iglesias, and Halbruegge) were invited to talk about their models at a symposium on model comparison held at the 9th International Conference on Cognitive Modeling in Manchester, UK this summer.

Further expanding on the work from the model comparison challenge, Dr. Gonzalez will be editing an upcoming special issue of the Journal of Artificial General Intelligence on Cognitive Architectures, Model Comparisons, and AGI. All participants of the model comparison challege will be invited to submit a paper to the special issue on their model. Other submissions from those in a position comment on a number of topics relevant to model comparison will also be encouraged. So please keep an eye out for the call for submissions!

In collaboration with Christian Lebiere, a research faculty member in the Department of Psychology, Dr. Gonzalez recently obtained a five-year, $1.75 million grant from the Defense Threat Reduction Agency to conduct basic research to determine the socio-cognitive factors that lead to conflict between two constituencies and the factors that aid in conflict resolution.

Dr. Gonzalez is also investigating solutions for the Cyber Situation Awareness problem through a five-year, multimillion dollar Multi-University Research Initiative grant in collaboration with Penn State University and Arizona State University.

Dr. Gonzalez has also obtained a two-year grant from the National Institute for Occupational Safety and Health to conduct research that will be used to develop and test technology that can aid miners in escaping an underground mine following an emergency situation (e.g., explosion, sustained mine fire, equipment fire, or gas or water inundation).
