Overview
Virginia Byers Kraus, MD, PhD, is the Mary Bernheim Distinguished Professor of Medicine, Professor of Orthopaedic Surgery, Professor of Pathology and a faculty member of the Duke Molecular Physiology Institute in the Duke University School of Medicine. She is a practicing Rheumatologist with over 30 years’ experience in translational musculoskeletal research focusing on osteoarthritis, the most common of all arthritides. She trained at Brown University (ScB 1979), Duke University (MD 1982, PhD 1993) and the Duke University School of Medicine (Residency in Internal Medicine and Fellowship in Rheumatology). Her career has focused on elucidating osteoarthritis pathogenesis and translational research into the discovery and validation of biomarkers for early osteoarthritis detection, prediction of progression, monitoring of disease status, and facilitation of therapeutic developments. She is co-PI of the Foundation for NIH Biomarkers Consortium Osteoarthritis project. Trained as a molecular biologist and a Rheumatologist, she endeavors to study disease from bedside to bench.

Plasma extracellular vesicle signatures of metabolic health and exercise response in a pilot study of older adults.
Journal Article Am J Physiol Cell Physiol · February 1, 2026 Extracellular vesicles (EVs) are key mediators of intercellular communication and regulators of cellular function, yet their roles in metabolic health and exercise response are poorly understood. This pilot study analyzed plasma from older adults (n = 20) ...

Journal Article iScience · January 16, 2026 Caloric restriction (CR) extends lifespan and enhances healthspan across species. In humans, the CALERIE Phase 2 trial demonstrated that CR improves inflammation, cardiometabolic health, and molecular aging. To explore underlying mechanisms, we examined CR ...
