Florian Kas, MD

Rheumatologist, Postdoctoral Fellow of Medicine

University of Pennsylvania Perelman School of Medicine

Dr. Käs’s interest in vasculitis began during his medical training at the University Hospital of Zürich, Switzerland, where a strong focus on nephrology gave him a solid foundation in both systemic and organ-specific manifestations of vasculitis. Drawn by the field’s diagnostic and therapeutic challenges and the opportunity to improve patient care, he chose to pursue rheumatology.

As a 2025-2026 Vasculitis Clinical Research Consortium-Vasculitis Foundation Fellow, Dr. Käs aims to become a well-rounded clinician-researcher, advancing the diagnosis, management, and understanding of vasculitis while actively engaging with the international vasculitis community and its experts and patient advocates.
