Genome editing, functional genomics, and cells figuring out how to eat themselves without dying. Professor of Genome Biology at ETH Zürich.
Congrats to Moritz Schlapansky, who successfully defended his PhD thesis on Friday! You can read his work on "scOUT-seq" profiling of single cell transcriptomes + editing outcomes in millions of cells and living mice at www.biorxiv.org/content/10.1...

In 2026 I'm taking a sabbatical in @peterfineran.bsky.social lab @universityofotago.bsky.social. I'm looking forward to learning a lot from Peter's lab and excited to get back to my prokaryotic/viral roots! Also planning to some trips to the rest of the Pacific and Asia. So much to look forward to!

Sometimes #Cas9 is too dang big. But mini Cas proteins are bad at both NHEJ & HDR. PhD student Fedor Gorbenko used mammalian cell evolution for *HDR* to make REALLY super #Cas12f1 and #TnpB. As good as or better than Cas9! Base editors included! www.biorxiv.org/cgi/content/short/2025.10.27.684765v1
Directed evolution of compact RNA-guided nucleases for homology-directed repair in mammalian cells
RNA-guided nucleases enable DNA editing and offer promise for treating genetic diseases, particularly when used for precise sequence replacement. However, many of the most effective enzymes, such as S...

Thanks to CRISPR/Cas technology, researchers can precisely edit genetic material to treat hereditary diseases. To achieve this, they need to identify undesirable cuts in the genome at an early juncture. Pioneer Fellow Lilly van de Venn is developing such testing methods. ethz.ch/en/news-and-...

Ever noticed that #CRISPR editing results differ between cells? Awesome PhD student Moritz Schlapansky developed "scOUT-seq" to measure single cell transcriptomes + editing. 1.2 million cells, 74 cell types, living 🐭. Cell subtypes differ wildly from bulk average! www.biorxiv.org/content/10.1...
Cell-stereotyped DNA repair outcomes are widespread during genome editing
Genome editing outcomes are governed by DNA repair pathways that vary with cell type and state. We developed scOUT-seq (single-cell Outcomes Using Transcript sequencing), a scalable approach that join...

Long time no see, everyone! Things have been a bit more busy than ususal, hence the radio silence. But stay tuned for some fun news in the next few days.

New #preprint from the lab! Do you want to see the invisible? So did we! When DNA genomes get broken, cells somehow find related sequences to fix the break. But how do they find it? We developed a way to look at sequence *search*, not just sequence usage.

Cells are filled with toxic stuff that damages healthy proteins. Is that garbage just left to rot on the curb? No way! Ubiquitin ligases have evolved to recognize chemical damage and clean it up! www.nature.com/articles/s41...
C-terminal amides mark proteins for degradation via SCF–FBXO31 - Nature
SCF–FBXO31 scans proteins for C-terminal amidation and marks them for subsequent proteasomal degradation.
