Dr. Webel is an Assistant Professor of Nursing at the Frances Payne Bolton School of Nursing at Case Western Reserve University. She is a nurse scientist interested in Studying and promoting healthy lifestyle behaviors in adults living with HIV. Her recent work investigates how a nurse-led intervention can be adapted to improve cardiovascular health in adults living with HIV (EXTRA-CVD), the relationship between exercise and diet intake and the symptom experience in adults living with HIV (PROSPER-HIV), and the effect of perceived risk of cardiovascular disease on healthy living behaviors in adults living with HIV. Her work has been funded by the National Institute of Nursing Research, NHLBI, the American Heart Association, the Center for AIDS Research, as well as private foundation grants.

Visiting Scholar 2017-2018

Short bio: My interest in HIV began before I started my master's training, when I analyzed the effects of an exercise intervention on health outcomes of this population. After that, I examined the relationship between HIV infection and physical fitness outcomes, as well as the effects of different exercise interventions for this population. During my master's training, I helped conduct a research project to understand the effects of a combined exercise training on different outcomes, such as muscle strength, body composition and health-related quality of life. With these data, we also analyzed the associations between HIV infection and muscle strength, as well as sex-related changes that occur in this variable. For my PhD, I will continue examining changes that occur on muscle strength over the HIV-infection, but to include information about neuromuscular activation and physiology of muscle tissue.
