My career has been focused on patient-oriented research. I have been a life-long Michigan resident but left briefly for training as a pediatric resident at New York University. I returned for sub-specialty training as a fellow in hematology-oncology at the University of Michigan. Wonderful mentors, patients, and families led me toward the field of hematopoietic cell transplantation (HCT). Through additional hands-on training in Clinical Research Design and Statistical Analysis at the University of Michigan School of Public Health, I was equipped with skills to conduct well-designed clinical and translational studies. I have been fortunate to work with a great team of interdisciplinary investigators examining clinical and health-related quality of life (HRQOL) outcomes in the HCT field. This stemmed from a deep interest in the translation of novel agents to help prevent a major complication that occurs in patients after allogeneic HCT known as graft-versus-host disease (GVHD). With this interest, I appreciated the important need to better support caregivers who provide care for their loved ones (patients) 24/7.
These two areas of research (GVHD, caregiving) have formed the basis of our team’s research goal to implement and disseminate a scalable product that optimizes caregiver health and well-being, which will, indirectly lead to more effective patient support and improved clinical outcomes. While illness impacts the patient directly, the complete picture of human disease is a collage of the affected patient and family caregiver, experienced by both. As a clinician, I have the privilege to intervene and provide care to patients but also recognize the role to intervene and provide training, coping skills, and self-management strategies to caregivers. This model of family-centered care has inspired me as both a clinician and a scientist. In this NIH-funded Roadmap 2.0 project, the goal is to conduct a two-arm randomized clinical trial where participants (caregiver-patient pairs) will be randomized to a mobile health app arm or to a control arm (or usual care). Our team is very enthusiastic about pursuing the proposed work because we will leverage new technology and novel data analytic tools, which may provide greater insight in patient and caregiver outcomes for future work.

Dr. Barton is currently the Associate Dean for Research and the Mary Lou Willard French Endowed Chair of Oncology Nursing at the University of Michigan School of Nursing. Her research career has focused on oncology symptom management since 2002, having developed, implemented and completed 13 large multi-site intervention trials. Dr. Barton has expertise with clinical trial methodology and symptom self-management, particularly cancer related fatigue and sexual health. Dr. Barton has developed phase II and III clinical trials in a variety of oncology related symptoms including fatigue, hot flashes, peripheral neuropathy, sleep problems, cognitive changes related to chemotherapy, nausea and vomiting, and sexual health using pharmacologic and behavioral interventions such as hypnosis and imagery as well as dietary supplements. Dr. Barton develops complex interventions to improve the health related quality of life of cancer survivors who are facing multiple physical and mental health related issues. Dr. Barton has also focused on mechanistic secondary aims in symptom intervention trials, with support from the Breast Cancer Research Foundation and American Cancer Society in addition to NCI funding for phase III trials. The phase III trials evaluating testosterone for libido, ginseng for fatigue and vaginal dehydroepiandosterone for vaginal atrophy all included translational aims that provided data for hypothesis generation on the mechanism of action of the intervention as well as predictors of symptom expression.
