Scientists have no direct access to truth. Therefore, we infer our level of understanding from our ability to predict future events. The most successful sciences predict future events by building precise, quantified models of the systems under study. Most sciences that successfully deploy the building and testing of quantitative models (e.g., physics, astronomy, chemistry, etc.), have a select few specialists who build their models. 

I build quantified models of the cognitive systems that produce human behavior. When building models, I ask the question, “How does perception influence choice?” This question is the common theme that links all my research, from my model of value-based choice (Psychological Value Theory) to my translational research addressing literacy and clinical disorders.
