Julius Keyl

Team Lead RWD xAI

Institute for AI in Medicine, Germany

Julius studied medicine at LMU Munich, focusing on cancer immunotherapy and computational oncology. He is currently a clinician scientist at IKIM, where he combines explainable AI and large-scale multimodal data to improve treatment decisions for cancer patients. His goal is to develop personalized AI models based on real-world data that serve as patient-specific digital twins in routine care.
