Gemini Meeting – Geneva, 17–18 November 2026, Centre Médical Universitaire, Faculté de médecine – Université de Genève
A heartfelt thank you to all participants who joined us for two inspiring days dedicated to digital twins in stroke care. The workshop was hosted by Sandrine Morel and Philippe Bijlenga, with the support of Alexandra Portilha and Abriam Sandralegar from the Hôpitaux Universitaires de Genève.
We were delighted to welcome around 50 participants from partner institutions and local groups who joined following the open announcement shared within our networks.
🔍 Highlights of the Meeting
• Opening Session – Spotlight on the Work of Prof. Ivan Olier (Liverpool)
The workshop opened with a session dedicated to Prof. Ivan Olier’s research within the Target and Aristoteles projects.
We presented his innovative approach to patient similarity graphs, where each patient is characterised through diagnoses and condition-specific factors. Similarity is computed using an original metric, enabling the construction of structured patient graphs that feed novel neural-network models. His work offers valuable insights for the digital-twin community.
• Cardiac Electrophysiology & Biomechanics – Geneva Team
Dipen Shah and Dyonisos Adamopoulos presented their latest research linking atrial morphology, vessel wall shear stress, fibrosis on MRI, and electrical abnormalities to guide ablation strategies.
A rich discussion followed on co-registration accuracy and the role of CT imaging as a reference.
• Work Package Progress
All teams reported steady progress, with the pieces of the puzzle progressively aligning. The first digital twins are emerging, and the community is now fine-tuning the launch of the upcoming clinical trial evaluating how digital twins can improve first-pass thrombectomy success.
• Data Science & Parallel Workshops
The afternoon began with an introduction by Christophe Gaudet-Blavignac to semantic technologies, FAIR data, and the vision of a new “Babel Tower” for modern scientific knowledge.
Parallel sessions then explored:
- Software delivery
- Bayesian networks
- First-pass treatment success & thrombus fragmentation twins
- Probabilistic estimation of aneurysm treatment success
- Data harmonisation
- Integrating multi-organ perfusion models with disease progression
The day concluded with the General Assembly and a final wrap-up workshop.
Culture & Networking
Participants enjoyed a guided visit of the exhibition “More than Meets the Eye” at the Musée Rath https://www.mahmah.ch/expositions/au-dela-des-apparences, led by Jean-Yves Marin, former director of the Geneva Museum of Art and History, and Nathalie Bijlenga, exhibition curator, followed by a warm networking dinner at the Kiosque des Bastions.
Building the Future of Digital Health
We sincerely hope this workshop helped align perspectives, strengthen collaborations, and create bridges with neighbouring communities working to advance human health through data, modelling, and digital-twin technologies—ultimately to reduce the burden of disease.
