What I do
I study how people make judgments and decisions; how these processes shape behavior at the individual, group, and organizational level; and how we can help people make better judgments and decisions. I investigate these questions with computational modeling and methods from the behavioral, cognitive, and neuro- sciences. When I’m not at my desk you can find me running, biking, rowing, or out in the woods. In a parallel world, I own my own bike shop in the Midwest.
COMPUTATIONAL DECISION SCIENCE
Decisions, almost by definition, link our thoughts to our actions. My research uses computational models to characterize this critical link forcing us to specify the mental processes (i.e., memory, learning, or reward evaluation) involved in making a decision, the environments those choices take place in, and the interaction between the person and the environment. By taking this approach, we develop a better understanding of how the mind works and formulate mathematical models to help individuals, groups, and organizations, make better decisions.
