Research

We study how the spatial organization of tissue shapes cell state, disease progression and response to therapy. We develop interpretable AI/ML and optimization methods that turn imaging, single-cell and spatial omics data into mechanistic hypotheses and clinical prediction.

We are affiliated with the Institute for Computational Biomedicine and the Translational Spatial Profiling Center at Heidelberg University and Heidelberg University Hospital. We are members of ELLIS (European Laboratory for Learning and Intelligent Systems), the Interdisciplinary center for scientific computing, and contribute to the Scientific Machine Learning initiative at Heidelberg University.

We work at the intersection of AI and biomedicine to address a fundamental challenge in biology and medicine: understanding the principles governing tissue organization and plasticity. We study how the spatial organization of tissue shapes cell state, disease progression and response to therapy. The measurements are single-cell resolved and spatially structured, the labels sit at the level of the sample or the patient, and the organization itself is unannotated. We therefore treat these as problems of learning structured representations under weak supervision on geometric data, and we constrain the models to remain readable, since their output is a hypothesis that has to survive testing at the bench or in the clinic.

  • Cell state depends on tissue context. The molecular state of a cell is predictable in part from its surroundings, and the contribution of context can be separated from the contribution of the cell itself. We build multiview and graph-based models that keep this decomposition explicit rather than absorbing it into a single latent space, across transcript, protein and imaging modalities.
  • Contextual programs are local and persistent. Patterns of intra- and intercellular relationship recur at consistent spatial scales across samples and conditions, which makes them learnable from sample-level labels without cell-level annotation. We develop compressed representations that preserve this locality, so that what the model used remains recoverable.
  • Tissue organization changes in structured ways. Spatial programs are reconfigured across disease stages and under therapeutic pressure, and those trajectories are constrained rather than arbitrary. We formulate this as an alignment and transport problem over tissue geometry, to reconstruct how organization evolves and to generate hypotheses about adaptation, immune evasion and resistance.
  • Tissue geometry carries clinical signal beyond molecular composition. Spatial arrangement predicts progression and therapeutic response where composition alone does not. We build explainable models that expose which spatial patterns drive a given prediction and distil them into compact, testable descriptions of tissue for patient stratification.

We value collaborations with clinical, experimental biology groups and groups working on the development of novel methods for the acquisition of single-cell spatial omics data. We welcome synergistic collaborations with computational groups towards the construction of more robust theoretical and computational frameworks for the analysis of all aspects of biomedical data and beyond.

Tools

The Multiview Intercellular SpaTial modeling framework (MISTy) is an explainable machine learning framework for knowledge extraction and analysis of single-cell, highly multiplexed, spatially resolved data. MISTy facilitates an in-depth understanding of intra- and intercellular relationships. MISTy is a flexible framework able to process a custom number of views describing a different spatial or functional context such as intracellular or broader tissue structure, cell-type composition, functional footprints or anatomical regions.

Kasumi is a method for the identification of spatially localized neighborhoods of intra- and intercellular relationships, persistent across samples and conditions. Kasumi learns compressed explainable representations of spatial omics samples while preserving relevant biological signals that are readily deployable for data exploration and hypothesis generation, facilitating translational tasks.


DOT is a method for transferring cell features from a reference single-cell RNA-seq data to spots/cells in spatial omics. It operates by optimizing a combination of multiple objectives using a Frank-Wolfe algorithm to produce a high quality transfer. Apart from transferring cell types/states to spatial omics, DOT can be used for transferring other relevant categorical or continuous features from one set of omics to another, such as estimating the expression of missing genes or transferring transcription factor/pathway activities.

TOAST (Topography-aware Optimal Alignment of Spatially-resolved Tissues), is a spatially aware Fused Gromov-Wasserstein (FGW) framework for intra-, intersample and temporal alignment of spatial omics data, which explicitly incorporates spatial constraints into the optimal transport objective. TOAST transfers annotations across aligned samples, recovers differentiation trajectories and maps single cells to spatial locations.


ContextFlow is a context-aware flow matching framework for inferring structural tissue dynamics from longitudinal spatially resolved omics data. It integrates local tissue organization and ligand-receptor communication patterns into a transition plausibility matrix that regularizes the optimal transport objective. By embedding these contextual constraints, ContextFlow generates trajectories that are not only statistically consistent but also biologically meaningful, making it a generalizable framework for modeling spatiotemporal dynamics.

SpaCEy is an explainable graph neural network that uncovers organizational tissue patterns predictive of clinical outcomes. SpaCEy learns directly from molecular marker expression by modeling tissues as spatial graphs of cells and their interactions. Its embeddings capture intercellular relationships and molecular dependencies that enable accurate prediction of variables such as overall survival and disease progression. SpaCEy integrates a specialized explainer module that reveals recurring spatial patterns of cell organization and coordinated marker expression that are most relevant to the model's predictions, distilling compact protein marker sets plus spatial context for improved patient stratification.
