Our lab investigates how to help adults with HIV age well. We use rigorous and innovative research techniques to examine how non-pharmacological approaches prevent and mitigate chronic disease, reduce symptoms, and improve quality of life in people living with HIV.
Can a nurse-led intervention improve cardiovascular health in HIV?
Does High Intensity Interval Training reduce fatigue & improve function in older adults with HIV ?

The University of Washington Webel Research Lab, was founded by Dr. Allison Webel in the School of Nursing, with the mission to conduct rigorous, high-impact clinical research informing healthy aging and HIV. We are deeply committed to community-engaged research studies that center our research questions and methods on people living with HIV (PWH) and their families. Webel Research Lab projects range from longitudinal studies of symptom response to physical activity and nutrition in older PWH, to clinical trials of exercise interventions, and implementation sciences studies testing nurse-led interventions to improve cardiovascular health in PWH.
We value:
-
- Diversity and seek to meaningfully include PWH on our team
- Critical questioning of assumptions, approaches, and data
- Healthy aging in PHW through mitigating symptom burden
- Interdisciplinary and global collaboration
- Research that can directly improve the lives of PWH everywhere
We are a busy, dynamic, and collaborative research lab, involved in research studies designed to identify, understand, and help older PWH age well. Guided by our commitment to meaningful community engagement, we are dedicated to bringing our research findings and knowledge to PWH and healthcare providers throughout the region and the globally.
