Meet the team
Dr. Artur Hahn
Artur holds a PhD from Heidelberg University, having transitioned from theoretical particle physics to medical physics and machine learning in biomedical research. At Heidelberg University Hospital, he developed AI methods for early cancer diagnosis, connecting large-scale imaging with microscopic tissue changes and revealing diagnostic features in multimodal physiological data. For the past decade, he has been creating high-performance automation pipelines for data processing and enhanced medical imaging with AI, using machine learning, deep learning, computer vision, and generative AI. After seven years in academic research at leading institutions, he joined Philips Research to develop medical imaging technology, focusing on MRI, quantum sensing, AI-based signal processing and monitoring, and GenAI for workflow automation.
Artur started HA AI Consulting with the goal of expanding his experience to new domains and applying creative problem solving with cutting-edge technology to more challenges in everyday work life. With a strong positive conviction of AI's potential to support people in meaningful ways, he hopes to contribute in countering current mental health trends by reducing stress in professional environments.
