Among the most defining characteristics of our species are the capacities for a rich sense of self and the depth of our social cognition. How does the human brain build models of ourselves and other people, and how do we use this information to guide our behavior in the real world? Dr. Chavez is an interdisciplinary researcher who uses a combination of multimodal neuromaging (e.g., fMRI and diffusion MRI) and computational methods to understand how the brain represents information about the self, the people around us, and the cognitive and emotional mechanisms that support these processes. As such, his work draws on theoretical and methodological approaches from cognitive neuroscience, social and personality psychology, and data science to generate mutually informative insights across multiple levels of analysis.
Dr. Chavez is interested in accepting new doctoral students for Fall 2025.
