Epithelium Microbiome lnteractions

We are coordinating the BACTORG consortium (with Melanie Börries from Freiburg) to yield translational breakthroughs in cancer microbiome science in cooperation with 7 leading medical centers in Germany and the Netherlands. Using patient-derived bacterial strains and organoids, we validate the functional relevance of clinical multi-omics datasets. In doing so, we envision to design personalized prevention and treatment strategies for colorectal cancer that take the gut and tumor microbiome into account.

In collaboration with several international partners, we are exploring the role of the microbiome in liver cancer development, progression and treatment response. Using patient-derived organoids of different types of liver cancer and tumor-relevant bacterial strains, we perform diverse phenotypic assays to elucidate functional roles of these bacteria for subsets of liver cancer patients. 

In collaboration with Emulate Inc, we develop next-generation organ chip platforms that allow us to study the impacts of bacteria on colorectal cancer migration and metastasis formation. Using diverse patient-derived organoids and further microenvironmental components, we re-build the complexity of the tumor microenvironment one step at a time.

Projects in our group are meant to generate groundbreaking basic scientific insights and translate those to patient benefit in cancer prevention and treatment. Your project with us should allow you to follow your own scientific interests in collaboration with the team and boost your scientific profile. Therefore, your project will emerge from the intersection of your experiences, future plans, and what our lab environment can enable you to do. Most PhD and postdoc projects in our group can be summarized in 2 categories:

1. Functional studies on bacterial strains in cancer development and progression. 
These include organoid and organ chip culturing, bacterial culturing, genetic engineering with CRISPR Cas9, co-culture development, immune cell co-cultures and mouse model transplantations.

2. Integrative bioinformatics of host and microbiome in patients.
In this type of project, you can do up to 80% dry lab work, coupled to generating your own datasets and validating the patterns you discover together with group members and external collaborators. Our focus is on host transcriptomics (single cell and bulk), bacterial strain whole genome sequencing and microbiome-targeted sequencing of patient tissues.
