about me
I'm a Postdoctoral Researcher at the Princeton Neuroscience Institute, working with Jon Cohen, Ken Norman, and Nick Turk-Browne (Yale University). I earned my Ph.D. in Computer Science from the Vision Lab at Stanford University, co-advised by Fei-Fei Li and Diane Beck (University of Illinois). Before that, I received my B.A. from Williams College in Computer Science, Mathematics, and Cognitive Science.
research interests
My research program uses applied machine learning to study the mechanisms of
visual and semantic categorization in human behavior and in the human brain.

We rely on vision more than on any other sensory modality to interact with and make sense of the world. My work uses applied machine learning to investigate how visual and semantic information is learned, organized into categories, and actively modulated in our behavior and in our brains.
I take an interdisciplinary approach to this problem that involves developing advanced computational tools applicable to a diverse array of experimental techniques, including psychophysics, functional neuroimaging (fMRI), and real-time neurofeedback.
