Dr. Bell is the recipient of the Norma B. Anderson Prize in Medicine from Johns Hopkins Hospital and a Physiology Society (UK) Award for Research. Her research interests are focused on the impact and diagnosis of frailty in individuals with cardiovascular disease and the use of non-invasive imaging techniques. Her work includes long term outcomes of older adults with frailty following hospitalization and the use of non-invasive imaging techniques to further advance mechanisms of the frailty syndrome. Since 2012, Dr. Bell has collaborated with Dr. Jefferson and the ICU delirium team on the Memory & Aging Project where Dr. Bell is examining the association and long-term impact of frailty on diastolic cardiovascular function and impaired blood pressure augmentation.
