Hi, I'm Qingfang

πŸ“„ View my resume (PDF)

I’m a research fellow at the Learning and Decision-Making Unit at the National Institute on Drug Abuse (NIDA), which is part of the National Institutes of Health (NIH) β€” the largest biomedical research agency in the world. I earned my Ph.D. in Psychology from The Ohio State University, where I specialized in cognitive and computational neuroscience in the Model-based Cognitive Neuroscience Lab.

My work bridges psychology, cognitive neuroscience, and computational modeling to understand how people learn, make decisions, and β€” more broadly β€” how intelligence emerges in the human brain.
