I am an interdisciplinary scientist with training in neuroscience, psychology, and engineering. I want to understand psychological experiences through a scientific lens. My research aims to understand what emotions are and what role they play in healthy psychological functioning.
Big questions: How do emotions and other motivational states impact the brain, behavior, and other biological functions? If we could build a tool (like a thermometer) that could objectively measure an emotion, how would it work? Can artificially intelligent agents have emotions? How is emotion related to time and space?
My interest in psychology began in the field of music: I did some work in the domain of music psychology as an undergraduate (MuE) and master’s student (Bregman Media Labs). Then, during my PhD (Dartmouth), I studied facial expressions, learning theory, and mathematical modeling, and I learned how to apply neuroimaging techniques to psychological questions.
