A promotional graphic for an oral presentation at the EACL 2026 conference in Morocco. The background features a sunny, historic Moroccan stone fortress gate with palm trees, a clear blue sky, and decorative geometric tile patterns in the corners. Text in the top left indicates the event is at Palais Des Congres, Rabat, from March 24-29, 2026. A banner across the middle displays the presentation title: "Unintended Memorization of Sensitive Information in Fine-Tuned Language Models." Below the title is a flowchart diagram illustrating how Large Language Models (LLMs) trained on sensitive medical text can inadvertently memorize Personally Identifiable Information (PII), and how a "True-Prefix Attack" can extract a patient's name even when fine-tuned for downstream tasks that do not contain PII. Text at the very bottom reads, "Oral Presentation: March 27 | 11:00 AM | Salle La Palmeraie."

Thrilled to present our paper "Unintended Memorization of Sensitive Information in Fine-Tuned Language Models" at #EACL2026 in Rabat! 🇲🇦

Large dense models are often difficult to run on clinical devices.
Instead, this approach uses MoEs to create a sparser, more specialized architecture for different patient demographics and imaging types.
The results: among other improvements, a reduction of up to 76% in inference costs!

Great having Robbie Holland back for a visit at our lab!

He’s at AIMI at Stanford University and gave a speech on auto-generated hypotheses in the context of AI4Science. Not only for the lab, but maybe more importantly for our lab‘s seminar on Multi-modal AI for Medicine (IN2107, IN45072).

🎄 Lab Christmas Party! 🎄

It's always great to use the holiday season as an opportunity to (re-)connect!
We had a blast at our Christmas party with lots of laughs, pizza, and Glühwein 🍷

Wishing everyone a good end to this year and happiest of holidays to those who celebrate! ✨ #AIMsocial

Great being at #NeurIPS last week!

We celebrated the 5th anniversary of our research chair at @tum.de! 💙🥂

It's been an incredible journey of research and collaboration. Thank you to everyone who has made this possible. We are very much looking forward to the next years to come!

Quick look back at an insightful day yesterday at the Bavarian Conference on AI in Medicine, where @paulhager.bsky.social , @luciehuang.bsky.social, Alina Dima, and Vasiliki Sideri-Lampretsa were representing us.

Team, thank you for being such good ambassadors! 👏

However, that’s not all! Yundi is currently extending the framework by integrating K-space signal data and genomic information to further enhance its multimodal capability.

By doing this, ViTa enables a broad spectrum of downstream applications, including cardiac phenotype and physiological feature prediction, segmentation, and classification of cardiac/metabolic diseases within a single unified framework.

ViTa is a multi-modal, multi-task, and multi-view foundation model that delivers a comprehensive representation of the heart and a precise interpretation of individual disease risk. It integrates anatomical information from 3D+time cine MRI stacks with detailed patient-level tabular data.

Towards cardiac MRI foundation models: Comprehensive visual-tabular representations for whole-heart assessment and beyond Cardiac magnetic resonance (CMR) imaging is the gold standard for non-invasive cardiac assessment, offering rich spatio-temporal views of the heart’s …

We are wrapping up our 5th-year anniversary paper series with ViTa by Yundi Zhang et al. (www.sciencedirect.com/science/arti...), a work that adresses: How to realize personalized cardiac healthcare that moves beyond a single task?

But the work hasn't stopped there! Progress on the benchmark is tracked using an online leaderboard: huggingface.co/MIMIC-CDM, and we are currently developing the next generation of medical benchmarks in co-operation with Google for Health.

Models were found to perform significantly worse than doctors, to not follow guidelines, and to be extremely sensitive to simple changes in input. This means more work has to be done before we can safely deploy them for high stakes clinical decision making.

While LLMs aced standard medical licensing exams, the authors argued for evaluation in real-world clinical settings. So they developed a new dataset and benchmark that features and simulates real-world emergency room cases, and tests robustness and adherence to clinical guidelines.

Is it safe to use LLMs in the clinic today? This is the central question that @paulhager.bsky.social and Friederike Jungmann tackled in their 2024 study published in #NatureMedicine, which is our 5th-year anniversary's highlight paper this week.

Paul presented dynamic, temporally resolved lung imaging using INR-based registration. Steven focused on multi-contrast fetal brain MRI reconstruction for improved motion correction and image quality.

Thank you both for sharing your work and always welcome!

Last week we had the pleaure of hosting Paul Kaftan (Institute of Medical System Biology, @uniulm.bsky.social) and Steven Jia (Institut de Neurosciences de la Timone, @univ-amu.fr) for talks on the incredible potential of Implicit Neural Representations (INRs) in medical imaging.

We wish you success in all your future endeavors!

Huge and well-deserved congratulations to Dmitrii Usynin on successfully completing his doctoral journey in our lab! 🎊

Dima’s research has resulted in significant contributions to field of trustworthy artificial intelligence in particular for collaborative biomedical image analysis.

Since then, NIK's underlaying concept has kept significant traction, demonstrated by extensions like PISCO and the adaptation of the implicit k-space paradigm to other areas in the field like motion-resolved abdominal MRI (ICoNIK).
