Mackenzie Mitchell (she/her) is a graduate student in the Cognitive Psychology PhD program in the Department of Psychology and Neuroscience. She graduated with B.S. degrees in Neuroscience and Human Development from the University of Texas at Austin in 2017. After graduation, Mackenzie worked as lab manager for Jessica Church-Lang’s Developmental Cognitive Neuroscience Lab. At UNC, Mackenzie has focused her research on how functional brain network organization shifts across contexts (e.g., resting vs. exerting self-control) in children. She is also interested in how brain network development between childhood and adolescence relates to changes in executive function and psychopathology. Mackenzie received her M.A. in Cognitive Psychology at UNC in 2022.
