SNSF Ambizione group leader at ETH Zürich. Bacterial transcription factors 🧬
🥳 New preprint! 🥳
While planning molecular screening experiments, we went deep down a rabbit hole on group testing strategies to improve throughput. We present PoolPy, a tool to facilitate the design of pooled experiments.
This is still preliminary, happy to take feedback!

PoolPy: Flexible Group Testing Design for Large-Scale Screening
In large screening campaigns, group testing can greatly reduce the number of tests needed when compared to testing each sample individually. However, choosing and applying an appropriate group testing...

🥳 New paper out!
In this work, we identified small molecule effectors modulating the activity of transcription factors in E. coli.
Using metabolomics + transcriptomics, we could parse the entire regulatory network and predict signal molecules for 41 TFs!

A division of labor controls the degradation of fucoidans in the ocean
Fucoidans, complex polysaccharides produced by brown algae and diatoms, contribute to long-term carbon sequestration due to their resistance to microbial degradation1,2. While individual microbes can ...

We are searching for a postdoc in Marine Phytoplankton Metabolism and Carbon Storage! You'll get the chance to work in Belgium to combine high-throughput metabolomics and enzymes to study how microbes naturally sequester atmospheric carbon in organic marine molecules!
