Dr. Kerschbaumer is a postdoctoral scholar in the Division of Immunology and Rheumatology at Stanford University, conducting research in the Robinson and Khatri Labs. His work integrates clinical rheumatology with computational and systems immunology, applying meta-analytic techniques on transcriptomic datasets to uncover mechanisms of autoimmunity and improve therapeutic strategies in rheumatology.

He trained in internal medicine and rheumatology at the Medical University of Vienna, Department of Medicine III, Division of Rheumatology, where he also completed his PhD under Professors Smolen and Aletaha on treatment outcomes in inflammatory arthritis, followed by his habilitation on strategies to optimize the interpretation of clinical trial data in rheumatoid and psoriatic arthritis.

Dr. Kerschbaumer has been actively engaged with the European Alliance of Associations for Rheumatology (EULAR), contributing as Fellow, Methodologist, and Co-Methodologist to multiple international taskforces, including the 2019, 2022, and 2025 rheumatoid arthritis recommendations and the 2019 and 2023 psoriatic arthritis recommendations.
