Research Summary

My research takes a joint experimental and computational modeling approach to study human judgment, decision making, and reasoning.  I study how people make decisions when faced with multiple, complex alternatives and options involving different risks and rewards. To address these questions, I develop probabilistic and dynamic models that can explain behavior and use hierarchical Bayesian methods for data analysis and model-based inference. I am also interested in combining machine learning techniques with cognitive models to study naturalistic human decision making. Recent research topics in my lab include understanding (1) how context affects multialternative, multiattribute choice, (2) how dynamically changing information impacts decision processes, and (3) how physicians make decisions from medical images.
