My research has been in the functional imaging field in humans focusing on the mechanisms by which the brain normally integrates information from different sensory organs to perceive the external world and react by planning and executing movements that are accurate in time and space. Current studies focus on the functions of the cerebellum. Behavioral and functional imaging methods are utilized to investigate the role of the cerebellum in sensory perception and movement coordination. Our current projects aim at defining the role of the cerebellum in sensory perception and sensori-motor integration with an overarching hypothesis that the cerebellum mediates timing of both motor and non-motor operations. I have also been active in collaborating locally and nationally with experts in cerebellar disease and MRI imaging to conduct multi-center studies investigating ataxia pathophysiology , its progression and monitoring novel therapeutic interventions.
