Associate Professor, Department of Communication Disorders
I am interested in research that advances behavioral assessment and treatment of adult neurological communication disorders. Specifically, I am interested in understanding how language functioning and recovery after stroke is affected by mood and attention and in learning how to help people with aphasia transfer gains made in therapy to their everyday communication.

I am from Modesto, California and I love to wakeboard, try new foods, bake, and spend time with my family and friends.
