Talea Cornelius is a health psychologist and Assistant Professor of Medical Sciences at Columbia University Irving Medical Center. Her research situates mental health and health behaviors within a social context. In particular, she explores how an acute medical event, such as an acute coronary syndrome or a stroke, impacts patients and partners alike, and how partners can both facilitate and undermine patient well-being. Dr. Cornelius is also exploring novel applications of dyadic analysis to gain insight into interdependent, individual-level processes.
