Research Interests

My research focuses on the development and validation of optimal cognitive outcome measures for use in the clinical care and treatment of neurodegenerative dementias, with a focus on Lewy body dementia. Cognitive assessments must be responsive and adaptable, as well as align well with the priorities of people living with dementia and their care partners. This goal has led me to research less traditional methods of cognitive assessment than paper-and-pencil testing, such as performance-based assessments of activities of daily living, mobile health applications, and wearable devices. In parallel with the development and validation of pragmatic and meaningful outcome measures, my research program also explores complementary therapies for cognition, daily function, and overall wellbeing for people living with neurodegenerative dementias, including neurologic music therapy and cannabis-based therapies.
