Kyle BourassaKyle Bourassa, PhD

Kyle is a Postdoctoral Scholar working in the Moffitt-Caspi Lab at Duke University. He is funded by the National Institute on Aging through a T32 training grant (T32-AG000029) provided to the Center for the Study of Aging and Human Development in the Duke University Medical Center. Kyle received his B.A. from the University of Virginia in Psychology and History. He subsequently received his M.A. and Ph.D. in Clinical Psychology with a focus on Health Psychology from the University of Arizona. He completed his doctoral internship at the VA Puget Sound Healthcare System in Seattle.

Kyle’s research focuses on understanding the impact of stressful life events—such as divorce, bereavement, and trauma—on health across the lifespan. His work examines the social, behavioral, and affective mechanisms that link the experience of these stressors with dysregulated cardiovascular physiology, relevant disease outcomes, and mortality. To do so, Kyle makes use of both longitudinal cohort study designs and lab-based experimental paradigms, integrating top-down and bottom-up approaches. In addition to his work examining mechanisms of action, Kyle also studies how behavioral interventions might improve health among people who experience stressful life events.

liza-genaoLiza Genao, MD

Liza Genao received her medical degree in 2004 from UNPHU School of Medicine in the Dominican Republic. She completed training in Internal Medicine at Mayo Clinic in 2009 and Clinical Geriatrics at Duke University in 2011. Dr. Genao’s long term career is to improve the quality and equality of care of older adults with end-stage lung disease (ESLD). Her research seeks to understand the impact of aging and multi-morbidity on the functional status and quality of life of this population and derive specific multidisciplinary interventions targeted to those factors found to jeopardize these outcomes. The available medical treatments for ESLD minimally impact symptoms or change the disease progression, and involve challenges and barriers to which older patients are particularly vulnerable. Lung Transplantation (LT) and pulmonary rehabilitation (PR) are the best-demonstrated interventions to improve quality of life. As a result of the introduction of a new lung allocation scoring system (LAS) in the U.S. in 2005, the annual number of LT recipients 65 and older quadrupled. Having trained at Duke University, a leading center of excellence in LT, Dr. Genao became interested on analyzing how the lives of these older Americans changed by the gift of a new lung. During her first post-doctoral training year, under the mentorship of Drs. Kenneth Schmader, Heather Whitson and David Zaas, she completed an analysis of the difference in functional trajectories after transplant between older and younger recipients. This retrospective cohort study used data from the United Network for Organ Sharing (UNOS) registry on all adults that received their first LT after the LAS. The key findings of this study, recently published in the American Journal of Transplantation, were that on average, the functional status at 1-year was higher than at transplantation for all recipients, age was not associated with different rates of decline over time, and even the older recipients rarely reached significant disability at 48-months post LT. Dr. Genao ongoing studies include: survival benefit for older adults with LT compared to remaining on wait-list, causes of death after LT and healthcare utilization before and after LT in older Medicare Beneficiaries. In January of 2012, Dr. Genao’s participated, in a multidisciplinary workshop held by the Association of Specialty Professors, National Institutes of Health (including NHLBI, NIA, NIAID, NIDDK) and the American Geriatrics Society (AGS), to address issues related to kidney, liver, heart and lung transplantation in older adults and propose the agenda for future research. Also during this year she became an awardee of the Hartford Scholar in the Center of Excellence in Geriatric Medicine and Training program at Duke University. She has served in the AGS Junior Faculty Research Special Interest Group Steering Committee and the Duke Institutional Review Board since 2011. Dr. Genao is currently Medical Instructor, Department of Medicine, Duke University Medical Center.

JENNIFER R. DUNGAN, RN, PhD in Nursing Science with a Minor in Genetics from the University of Florida College of Nursing, 2006
Project (Project Mentor: William Kraus, MD): I have focused my training on two aspects of aging and genetics of cardiovascular disease: The first part of my project extends my dissertation work. It explores gene expression signatures of aging in cardiovascular disease using microarray. I am examining blood-based RNA from subjects in the Duke CATHGEN study of coronary heart disease to explore the effect of age on transcription profiles in people with a narrow burden of cardiovascular disease. This is an unbiased search for candidate genes that may help to explain some of the genetic contribution to aging in the context of heart disease. Second, I am focused on the genetic epidemiology of coronary artery disease and the phenomena of survivorship (survival in the context of having a chronic disease). Using a family-based database of early onset coronary artery disease (Duke GENECARD, PI: Elizabeth Hauser, PhD) and a population-based database of people who undergo cardiac catheterization (Duke CATHeterization GENetics/CATHGEN, PI: William Kraus, MD), I am exploring survival and survivorship in order to establish a proof of principle for the genetic contribution of this phenotype to heart disease. Through this project, I am also establishing a foundation in the study of temporal (time related) variables and their effect on gene association studies, so that we may better understand their impact on our analyses and appropriately control for their effects.

In her own words: The Duke Aging RTP has provided me with a strong foundation in aging focused research, allowing me the flexibility to explore my own area of interest (survivorship in coronary heart disease) while also engaging me in the important age-related research taking place at Duke and beyond. It has given me the opportunity to expand my level of expertise and research skills and present my research at such meetings as the American Society of Human Genetics and the Council for the Advancement of Nursing Science, to name a few. Overall, Duke University is a unique atmosphere that offers tremendous resources for training, career development, and even peer socialization. The Duke Aging Center has a long-standing tradition of excellence and accomplishment, but without a precocious atmosphere. I feel this program has strengthened my foundation in aging research, made me a more well-rounded researcher, provided extraordinary networking opportunities, and prepared me for a smooth transition into independent academic research.

Project: Diabetes and its precursor, metabolic syndrome, are major risk factors for cardiovascular disease (CVD). Metabolic syndrome – the clustering of CVD risk factors – is a particularly powerful precursor to CVD. The prevalence of each of these conditions increases with age and are the cause of significant disease burden and disability in elderly populations. The development of countermeasures for metabolic syndrome in middle aged populations has the potential to have dramatic implications for the disability of elderly Americans by preventing, delaying or mollifying the development of disease in the elderly. Understanding the mechanisms whereby lifestyle interventions, such as exercise, mediate beneficial effects can lead to the design of better and more effective strategies to prevent disease and modify quality of life in the elderly. While physical activity has been observed to improve insulin sensitivity in individuals with the metabolic syndrome, the molecular mechanisms responsible for these benefits have yet to be elucidated. The goal of my project was to determine the effects of long-term endurance exercise training on the insulin-signaling cascade in middle-aged patients with the metabolic syndrome with the goal of understanding the development of disease in aging individuals.

In his own words: The Research Training Program in Aging exposed me to different research disciplines and provided me with an appreciation for multidisciplinary research in aging. Topics covered during the weekly seminars were stimulating and informative, both on a professional level and a personal level.

Participation in the program also provided the opportunity for professional development. For instance, preparing the “mini-R01” grant proposal to gain acceptance into the program improved my writing skills and the experience of developing the proposal will be helpful when I write an actual R-01. In addition, Duke offers numerous opportunities for professional development through seminars (lasting from a couple of hours to 3 days), programs and other resources. Seminars cover topics such as: improving scientific writing, developing an R-01, and how to manage a lab.

solimeoSAMANTHA SOLIMEO, Ph.D. in Anthropology, University of Iowa, 2005; MPH in Gerontological Public Health, University of Iowa, 2002
Project – A Qualitative Study of the Older Male Experience of Osteoporosis (Postdoctoral Supervisor/ Mentor: Deborah T. Gold, PHD): This study will examine the self-reported experiences of community-dwelling men aged 50 and older with osteoporosis to improve our understanding of their social experience. In addition, the study will contribute to existing efforts to evaluate the reliability and validity of a recently developed measure of disease-related quality of life for male osteoporosis patients, the Male OPAQ. These aims will contribute to the larger goals of increasing knowledge about male osteoporosis patients, producing new information pertaining to male osteoporosis diagnosis and treatment, and developing a standardized instrument to measure disease-related quality of life among older men with osteoporosis.

In her own words: The Postdoctoral Fellowship has afforded me the opportunity to build upon my doctoral research by broadening my knowledge of how age and gender influence the experience of other chronic disorders in later life. It has provided me with the flexibility to translate my dissertation findings into published manuscripts. The fellowship has given me the institutional support to participate in professional organizations through committee work and scholarly presentations at the meetings of the Gerontological Society of America and the American Anthropological Association, as well as Editor of Anthropology & Aging Quarterly. The weekly seminars have introduced me to new areas of gerontological inquiry as well as to scholars from other disciplines who share similar research interests. Overall, the fellowship has been an important and productive experience, effectively bridging graduate school to an academic position.
