Research Focus
Dr. Randolph S. Marshall's lab focuses on understanding how blood flow issues in the brain can affect cognitive function in patients with asymptomatic carotid artery stenosis. They're investigating whether interventions like carotid revascularization could help prevent cognitive decline in these patients. Their work combines advanced imaging techniques with clinical trials to explore treatment options that could improve brain health and potentially establish new guidelines for managing cognitive impairment related to vascular conditions.

Career totals from OpenAlex, compared against labs that share a department. A department spans everything from one paper to tens of thousands, so bar heights are on a log scale — otherwise the largest lab would flatten every other bar to a line.
