Our laboratory seeks to advance understanding, measurement, prevention, and treatment of functional disabilities in persons with multiple sclerosis (MS), with a particular focus on cognition and memory. We are developing innovative assessment tools to evaluate functional outcomes, and reevaluating and revising old assumptions about cognition and memory to improve treatment. My current NIH R01 is a longitudinal study of risk and protective factors associated with cognitive changes over time, with a focus on potentially modifiable factors that may inform clinical decision making.  As a member of the Corinne Goldsmith Dickinson Center for MS, I have the good fortune to collaborate with and learn from our expert team of MS neurologists. Frequent contact and feedback from our patients has also been essential for identifying clinically important questions with the greatest promise for improving quality of life for the persons striving to accomplish goals and live fully in the context of this disease.
