Dr. Bernard’s work seeks to understand how the cerebellum contributes to both motor and cognitive behavior. The cerebellum is located at the bottom and back of the brain, and is important for coordinating motor behavior as well as our thoughts. She completed her PhD at the University of Michigan in 2012, and followed this with a post-doctoral fellowship at the University of Colorado Boulder. She is the director of the Lifespan Cognitive and Motor Neuroimaging Laboratory. The goal of her work is to better characterize cerebellar changes over time with age, in conjunction with understanding how the cerebellum interacts with the rest of the brain. However, there are differences in this structure in older adults, and this is related to how older individuals perform both motor and cognitive tasks. In addition, Dr. Bernard is interested in better understanding cerebellar contributions to cognition more broadly. Increasingly, a role for the cerebellum in non-motor behavior has been demonstrated, but how exactly the cerebellum is contributing, and its contributions relative to the rest of the brain remain unknown. She is trying to discern the relative contributions of the cerebellum and prefrontal cortex to cognitive behaviors, to create better models and theories about behavioral performance. Finally, Dr. Bernard also has a line of research investigating contributions of the cerebellum to psychosis and the development of psychotic disorders.
