Following internship, residency, and both geriatric and internal medicine fellowships in Ireland she moved to Johns Hopkins in 2014. In addition to her clinical experience caring for frail older adults with multiple chronic conditions and teaching qualifications, she has extensive knowledge of many aspects of research. She led Ireland’s first population-based TIA epidemiology study and her Ph.D. focused on examining the clinical, etiological, and serum biomarkers that predict stroke after TIA. Since moving to the U.S., she has focused her attention on a number of projects around caregiving, improving communication around medication in skilled home health care, and improving the quality of home-based medical care received by frail elderly patients with multiple chronic conditions (MCCs). She is a co-investigator on a number of complex multisite studies specifically the Caring for Adults Recovering from the Effects of Stroke (CARES) study and the Caregiving Transitions Study. She directs the Linked Administrative Data Resource (LADR) linking administrative claims data to longitudinal studies on aging and leads analyses of NHATS and REGARDS CMS linked data examining healthcare utilization of people with MCCs and the effects of caregivers and other factors on that utilization. more
