Pioneering Applied Artificial Intelligence
From foundational NLP research to scalable medical data systems. We transform unstructured narratives into actionable science.
RESEARCH AREAS
NLP and Deep Learning
Basic Research in NLP
Our basic research focuses on foundation models for NLP, particularly reasoning, adaptation, and evaluation. We investigate how these models represent knowledge, reason over information, and generalize across tasks and domains. We designed and trained foundation models, such as Soofi, MedAlpaca, and medBert.
View Publications in Basic Research in NLPNLP in Healthcare
Together with leading health care providers in Germany we focuses on language models for representing patients and predicting clinical outcomes. More recently, we investigate long-context models and medical reasoning with foundation models.

We design methods to explain and benchmark foundation models, from visualizing internal representations to evaluating long-context understanding and reasoning. We study their capabilities, failure modes, and reliability in realistic settings.

We build interactive systems that make foundation models accessible and explainable. Our demos visualize model representations, support human-in-the-loop learning, and interactively explain model predictions.

Two research streams

Modular and Self-Improving Foundation Model Systems
Our researches modular foundation models that combine specialized components instead of relying solely on monolithic LLMs.
KEY HIGHLIGHTS
• SOOFI: A sovereign German-English foundation model based on a hybrid MoE Mamba-Transformer architecture.
• Reasoning Post-Training: Improving capabilities after pretraining.
• Global Exchange: Co-organization of the Shonan Seminar for empowering local open-source LLMs.

Interpretable Patient Representations with Foundation Models
Our develops interpretable patient representations from clinical text to support diagnosis, outcome prediction, and clinical decision support.
KEY HIGHLIGHTS
• medBERT.de: Domain-specific medical language models.
• S-PROTO & SPONGE: Sparse prototypical representations and cross-lingual knowledge transfer.
• Clinical Evaluation: CliniBench & DeepICD-R1 for medical reasoning and rare clinical outcomes.
