Research Interests

It is no exaggeration to say that motivated behavior and valuation of its outcomes is an integral part of daily life. The cortico-striatal brain network has been shown to play an important role in motivated behavior as well as in fatigue and depression that so many clinical populations experience, including individuals with traumatic brain injury and multiple sclerosis. Using functional neuroimaging, I investigate the functioning of the cortico-strital network during motivated behavior and its relationship with fatigue and depression. I also explore functional and effective brain connectivity in relationship with cognition in individuals with traumatic brain injury and multiple sclerosis.
