Florian Käs, MD
2025-2026 VCRC-VF Fellow
University of Pennsylvania,
Penn Rheumatology Vasculitis Center
Fellowship Focus:
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.
Over the next two years, 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.
