Nate Haines is a third year doctoral student studying clinical psychology at The Ohio State University (OSU). He received his B.A. from OSU in 2015, and his M.A. from OSU in 2017. Nate is interested in the role that emotion plays in how humans process, learn from, and make decisions based on rewards—particularly in the case of drug addiction and other externalizing disorders (e.g., ADHD). Currently, he is focusing on: (1) the role of emotion in learning and valuation, and (2) the relationship between impulsive and anxious personality traits and risky behavior. Nate uses cognitive modeling and machine learning techniques to explore these questions.
