Why?
Medicine traditionally meets in silos: conferences are built around specialties (radiology, pathology, laboratory medicine, etc.). But the data those specialties produce—structured test results, images, pathology reports—only reaches its full potential when different clinical perspectives meet data science, policy and industry.
Connect across and beyond medicine
We bring together clinicians, laboratory specialists, radiologists, pathologists, data scientists, legal and policy experts, and industry—so practical problems are discussed from every angle, not just one discipline’s viewpoint.
Turn routine diagnostic data into practical value
The summit focuses on near‑term, real‑world possibilities: how the data we already generate in clinical workflows can be used for better diagnostics, quality assurance, and research.
Collaborate responsibly
We encourage close cooperation with data scientists while respecting legal and ethical boundaries (GDPR, patient privacy, data governance). Practical, lawful workflows and safeguards are part of the conversation—not an afterthought.
Balance insight and interaction
D4 pairs short, focused talks from field experts with generous networking time and hands‑on demos so attendees can both learn what’s working today and make the connections needed to build it tomorrow.
Make impact, not just slides
D4 2026 is a compact, cross‑disciplinary meetup designed to move diagnostics forward by combining clinical expertise, data science, and policy in practical, ethically sound ways—while giving people time to connect, collaborate and invent together.

Who?
D4 2026 brings together people who actually build and run data‑driven diagnostics—across laboratory medicine, radiology, pathology, data science, policy, law, and industry. Our speakers share practical lessons from real deployments, honest challenges (yes, including the messy parts), and a clear focus on what matters most: better diagnostics for patients through collaboration.
Axel
Axel Unger is a healthcare innovation leader working at the intersection of AI, digital health, and service design. He focuses on turning emerging technologies into real-world, patient-centered solutions—bridging strategy, implementation, and the human side of innovation. At D4 2026, he will set the stage with a keynote on leading innovation in the age of AI.
Joe
Jochen Lennerz is a physician‑scientist and pathologist at Harvard Medical School / Massachusetts General Hospital, where he helps lead work at the intersection of diagnostics, data, and integrated care.
At D4 2026, he brings a thoughtful, big‑picture perspective on how we define certainty and value in diagnostics in the digital age.
Evis
Prof. Dr. Evis Sala is a radiologist and academic leader in diagnostic imaging, with a strong focus on translating advanced imaging methods into clinical practice. At D4 2026, she will speak about human–AI interaction in diagnostic imaging—what it takes to move from promising research to tools that genuinely support clinicians in real workflows.
Arho
Arho Virkki works at the intersection of healthcare data, clinical informatics, and real‑world implementation, with a focus on turning large‑scale health data into practical benefits for research and patient care. At D4 2026, he will share examples from Finland on how data can be used responsibly to enable both scientific discovery and data‑driven care.
Nic
Nicolas Tétreault is a clinical biochemist and medical laboratory innovation leader from Canada, focused on bringing data‑driven methods into routine diagnostics. At D4 2026, he will share clinical insights from Canada’s first approved AI laboratory algorithm, showing how everyday lab data (like CBCs) can be turned into actionable, validated tools for patient care.
Christian
Christian Haverkamp works on the practical deployment of AI‑assisted clinical decision support systems (CDSS) in hospital settings, with a focus on turning promising methods into tools that fit real clinical workflows. At D4 2026, he will share lessons from applied AI‑assisted CDSS in Freiburg—what enabled implementation, what created friction, and what made adoption work.
Medeleen
Madeleen de Geus‑Bosma is a laboratory medicine expert at Leiden University Medical Center (LUMC) and is active in international standardisation work through the IFCC. Her focus is on how digital metrology, units, and nomenclature make laboratory data comparable and trustworthy—exactly the kind of foundation needed for safe, scalable data‑driven diagnostics and AI.
Gregor
PD Dr. med. Gregor Hörmann is a laboratory physician at MLL Münchner Leukämielabor, where he leads work in hematologic diagnostics with a strong focus on translating innovations into routine workflows. At D4 2026, he will share how AI is already being used in everyday hematology testing—from scientific foundations to implementation details and practical integration in the lab.
