Our group focuses on problem driven development of AI/ML approaches to data exploration, hypothesis generation and computational scientific discovery to facilitate translational biomedicine.

We currently focus on representation learning and (un-)supervised analysis of spatial omics data. We develop new and extend existing explainable, scalable and readily deployable methods for multi-view learning, graph neural networks, metaheuristic optimization and optimal transport to:

• Identify clinically relevant spatial regions and interactions by explanatory modeling and optimization of global and local tissue/condition specific persistent multicellular patterns.
• Learn higher order spatial structural and functional organization to form taxonomical models of tissues for comparative analyses and generation of in-silico samples.
• Integrate spatial multiomics data with databases of prior knowledge to discover context specific mechanistic insighs spanning multiple omics layers.

Our interest is to address questions of structure-function relationships in disease, progression and response to treatment.

We value collaborations with clinical, experimental biology groups and groups working on the development of novel methods for the acquisition of 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.

Positions

Interns/Master theses

We offer opportunities for internships and supervision of master theses. We recommend that the duration of the internships is no shorter than three months. To inquire and apply write to contact<at>tanevskilab.org. Please include a CV, information on relevant courses attended during bachelor and/or master studies as well as well as a cover letter describing your more specific interests in the work done in our lab.

Postdoc

We are looking for a postdoctoral researcher for a 2 year project on the topic of Identifying the clinical relevance of higher order tissue organization in the tumor microenvironment from spatial multiplexed omics data. The position is offered as part of the Health + Life Science Alliance Inter-institutional Postdoc Program. The position will be shared between the Tanevski Lab at the Heidelberg University Hospital and the Hartmann lab at DKFZ.

In this project, we are leveraging the MIBI (multiplexed ion beam imaging) platform established in the Hartmann lab, combined with the experience of the Tanevski Lab in representation learning, optimization and graph-based approaches. Our aim is to identify the different levels of structural and functional organization in tumors from colorectal carcinoma and breast cancer patients to better understand how cellular behavior impacts therapeutic responses and clinical outcomes. Beyond the immediate cellular neighborhood, we will expand the analysis both toward the broader tumor microenvironment and toward capturing higher-level organizational patterns.

The candidate should:

• Have either a degree in computer science, engineering sciences, physics or mathematics, or a degree in biological sciences or medicine with previous experience in computational work.
• Have experience programming in R or Python.
• Interest in spatial omics and cancer biology.

For all PhD and Postdoc postions we offer:

• Work contract and funding according to TV-L with all corresponding social benefits.
• Stimulating and supporting interdisciplinary research environment with access to international research networks.
• Access to state-of-the-art spatial omics and clinical data.
• Access to high performance computing infrastructure.
• Access to further training opportunities offered by the Heidelberg University and Heidelberg University Hospital.

To apply please submit a letter of motivation tailored to the position (1 page), CV and a list of references with contact details to contact<at>tanevskilab.org.
