What We Do

Our lab studies cognitive health in individuals with multiple sclerosis.  We have an active grant-funded research program that evaluates various aspects of cognition in this population.  We have a particular interest in the following areas:
- cognitive fatigability
- the impact of stem-cell therapies on cognition
- the relationship between cognition and various biomarkers of disease (e.g. imaging, sNfL)
- the assessment of cognition (e.g. psychometrics)
- the impact of exercise interventions on cognition

Our lab consists of a number of dedicated health professionals who are passionate about what we do.  It is our collective goal to improve the quality of life in those people with MS whom we serve.
