As a rehabilitation neuroscientist, Dr. Gomes-Osman is driven to answer questions that can impact people’s ability to live more functional and independent lives. She has published many research studies focused on figuring out ways to make rehabilitation therapies more effective for instance, by combining it with nerve stimulation and non-invasive brain stimulation. In addition to her interest in physical health, her work in recent years has focused on better understanding how we can promote brain health for individuals who are aging. This interest in brain health has stemmed both from scientific curiosity, and from experiencing the reality behind the statistics, witnessing memory deficits as a family member. She finds great joy in mentoring the next generation of physical therapy clinicians and clinician-scientists, whether it be in the classroom, or carrying out studies to disentangle the complex relationships between physical exercise, brain health and postural control in older adults and individuals with various neurological conditions.
