Research Interests and Publications
Among the most defining characteristics of our species is our capacity for a rich sense of self and 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? My research aims to better understand the biological mechanisms of social behavior. Specifically, I am interested in both the shared and dissociable psychological processes that underlie self-representation and social cognition and their representation in the brain. Employing methods such as multimodal neuroimaging (e.g., fMRI and DTI) and machine learning, my work investigates how these processes are reflected in the structure and function of distributed networks of the brain and how they predict individual differences in each domain. As such, research in my lab broadly draws on theoretical and methodological approaches from personality and social psychology, cognitive neuroscience, evolutionary theory, and data science.
Dr. Chavez will be seeking new doctoral students only for Fall 2023.
