It’s been a fun first few week of my sabbatical. Many exciting meetings w/ @peterfineran.bsky.social lab, learning new stuff and brainstorming ideas. And my own lab has been off to a crazy great start to the year. The early/late zoom meetings have me burning the candle at both ends…
Dunedin welcomed me to my sabbatical at @universityofotago.bsky.social with @peterfineran.bsky.social with style.
I’m an @univpugetsound.bsky.social alum. Super cool to see UPS STEM highlighted. 10/10 would recommend. Liberal arts education FTW.
Sometimes I'm excited to read a paper and every paragraph blows me away. And sometimes I'm just as excited and every paragraph leaves me wondering if the referees were sleeping on the job. Today it was one of the latter.

What controls expansion & contraction of DNA repeats (e.g. Huntington's)? We were thrilled to collaborate w/ the lab of Marta Olejniczak to find out. Check out the cool screen from @sebasiegner.bsky.social and @matthiasmuhar.bsky.social that reads out repeat sequence. www.biorxiv.org/content/10.1...
I’m very grateful to @ethz.ch @vseth.ethz.ch.web.brid.gy for a Golden Owl award. People who know me know that I respectfully decline science awards. But recognition directly by students hits different!
Congratulations to @sebasiegner.bsky.social who defended his PhD on Friday! His name will be on 6-7 papers by the time he leaves the lab, including a co-first Nature paper. What a superstar! Keep an eye out for his postdoc application 😉
Reposted in edited form b/c I realized my original post could have been misinterpreted.
I recently received an AI-generated referee report. Almost all suggested experiments were already main figures & referee admitted using AI when asked by the editor. But they claimed they only used AI to write. No way. Editors, what do you do in this case? Referees, at least read the paper!
For me, it was the referee who used AI. Though AI generated papers and edits are certainly a problem.
I just realized my original post could be read the wrong way. Paper was from my lab and out for review in a high profile journal. Four years of work by a dozen people in multiple labs and AI slop seem to have been the judge.
It has been disappointing to see the general lack of interest and investment into population genetics and genomic medicine in Switzerland. While we can resort to other national cohorts for research the country can only benefit if the know-how can be applied locally

957 proposals were submitted in the latest round of ERC Synergy applications. They expect to fund 50 which means around 5% success rate. This is really not sustainable and a lot of people are likely avoiding doing this knowing how poor the chances are.

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!
This was a great collaboration with the lab of Virginijus Siksnys!
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
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-...
This was an incredible collaboration with the labs of Randall Platt, Gerald Schwank, Steve Jackson, Helmuth Gehart, and Timm Schroeder. Special thanks also to the NOMIS Foundation who supported some of the very ambitious experiments.
Definitely true that epigenetic state can affect repair. We try to control for this by editing in highly expressed housekeeping genes with approx equal epigenetic states in all cells. And HDR is just one change. There are stereotyped differences in categorical and molecular end joining outcomes.
Generally true, but I'm pretty sure we're not seeing sampling error. If that were true, then equally populated cell subtypes would have similar differential outcomes. Instead, we can recover cell type solely by clustering on differential outcomes! And "stemmy" cells share outcomes across lineages.
There's some crazy stuff in this preprint. For example, did you know that some neuronal subsets actually do HDR with surprising efficiency?
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...
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.
Excited to share our latest preprint. Work led by PhD student @jordancjwilson.bsky.social with @profmarciniak.bsky.social, @villungerlab.bsky.social & our @erc.europa.eu partners @jcornlab.bsky.social & @loizoulab.bsky.social, that sheds light on the action of WEE1 inhibitors. bit.ly/4bDpxZl
Do you want to know about the invisible secrets of #HDR during #CRISPR genome editing? Check out our preprint at www.biorxiv.org/content/10.1.... New methods, crazy biology, and theft from the genome! From PhD student @charlesyeh.bsky.social
I’m still learning Bluesky, so now tagging people I mis-tagged. Sorry! @charlesyeh.bsky.social @albertomarin.bsky.social @fedeteloni.bsky.social @gerlichlab.bsky.social
