Research Interests

My research seeks to understand how people make decisions about what they want, both in the short-term and long-term. Decisions vary so much across people and situations. My research tries to explain this variability, using techniques such as neuroimaging, pupillometry, behavioral experiments, and computational modeling. I am especially interested in how our memories and our emotions impact our decisions about the future, especially when we have to trade off smaller, sooner rewards with larger, later rewards. I hope that the results of my research will not only help with the diagnosis and treatment of psychiatric conditions that are marked by disordered decision-making (such as addiction), but I hope it will also inspire strategies to help everyone make decisions that are in their long-term best interest.
