Dr. Ana-Maria Orbai is an instructor of medicine at the Johns Hopkins University School of Medicine. Her areas of clinical expertise include arthritis and rheumatology.

Dr. Orbai earned her M.D. from the Iuliu Hatieganu School of Medicine and Pharmacy, Cluj-Napoca, in Romania. She then completed internship and residency training in internal medicine at the Johns Hopkins University-Sinai Hospital program. Subsequently, Dr. Orbai pursued fellowship training in rheumatology at Johns Hopkins.

At the outset of her fellowship training, Dr. Orbai focused on research projects in systemic lupus erythematous (SLE) and contributed to the development of new classification criteria for SLE, published in 2012. Thereafter, in the second half of her fellowship, Dr. Orbai discovered her passion for patient-reported outcomes in the context of inflammatory arthritis, where she has since focused her research efforts.

Dr. Orbai joined the Johns Hopkins Arthritis Center and is actively involved in patient care with a predominant focus on psoriatic arthritis and rheumatoid arthritis. Her research efforts seek to understand, from patients, how they experience arthritis in their lives. This knowledge will build the foundation for choosing and designing measures of disease activity and health-related quality of life measures that can be used to improve the care and outcomes of people with arthritis. more
