Research Focus
Dr. Christopher John Rozell's lab focuses on understanding how the brain and body interact during decision-making processes that require physical effort. The lab is developing a new system to study these interactions in a naturalistic setting, especially in individuals with psychiatric disorders like depression. By measuring diverse biological signals simultaneously, the lab aims to improve our understanding of motivation and inform the development of better therapies.
