My second dissertation paper is now out in @natcomms.nature.com! Here we introduce the co-expression-wide association study (COWAS) method for identifying pairs of genes or proteins whose genetically regulated co-expression is associated with complex traits. 🧵⬇️ www.nature.com/articles/s41...

I'm excited to present this new model to detect positive selection on regulatory sequences, which has been 3 years in the making! Thanks to Alexandre Laverré and @phylogenetrips.bsky.social for their amazing work on this project. 😃 doi.org/10.1101/2025... Thread!

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 www.sfa-phrt.ch/success-stor...

SIB is organizing the next edition of #eccb2026 (Geneva, 31.08.2026 - 04.09.2026), and we are now inviting the community to submit their tutorial and workshop proposals. 👉 A great opportunity to share tools, methods and expertise with 1,000+ international participants. Deadline: 5 January 2026.

🧵1/ Excited to share our new paper introducing a new #singlecell assay: scTF-seq, a high-throughput single-cell approach to explore how transcription factor (TF) dose shapes cell identity and reprogramming outcomes. 🔗 www.nature.com/articles/s41... Big congrats to the entire team @EPFL & @SIAT_China

🚨 New preprint out! We reconstructed parental haplotypes in >440k individuals (UK & Estonian biobanks) to estimate assortative mating directly in the parental generation. This reveals intensified assortment in recent generations. www.biorxiv.org/content/10.1...

Wow! If this holds up, it will be a triumph of science (i.e., of many hundreds of dedicated scientists over decades) over a devastating disease.

Excited to share our latest manuscript, "Exposure accumulation drives age-dependent disease architectures and polygenic risk scores," led by Xilin Jiang: www.medrxiv.org/content/10.1... I am attempting an explainer thread for the first time here: (I am usually too exhausted to post one)

I wrote about gene-gene interactions (epistasis) and the implications for heritability, trait definitions, natural selection, and therapeutic interventions. Biology is clearly full of causal interactions, so why don't we see them in the data? A 🧵:

Study of 230,000 people finds many examples where the effect of a genetic variant differs depending on the parent of origin, especially for growth and metabolism - fascinating! Amazing study, congrats @rjhfmstr.bsky.social, @zkutalik.bsky.social and team 👏

Extremely cool paper from @rjhfmstr.bsky.social @zkutalik.bsky.social and team. I still need to get my head around how the same genetic variant has opposite effects depending if it’s maternally or paternally inherited and why.

🚨 News recherche Des caractéristiques telles que la taille, le métabolisme ou encore le risque de développer certaines #maladies peuvent être influencées de manière différente selon que le variant #génétique en cause provient de la mère ou du père. ➡ www.unil.ch/news/1754464...

Congratulations to Zoltan @zkutalik.bsky.social , Robin @rjhfmstr.bsky.social and the whole team for this fantastic work out today in ‪@nature.com 👍 ‬ www.nature.com/articles/s41... Your parents' genome matters more than you think 😉https://www.unil.ch/dbc/en/home.html @fbm-unil.bsky.social

🚨 Our parent-of-origin study is out in Nature! 🧬 Maternal and paternal alleles can have distinct — even opposite — effects on human traits, revealing a hidden layer of genetic architecture that standard GWAS miss. 🔗 www.nature.com/articles/s41... Highlights below!

Thrilled to see this project come to life — a huge team effort with collaborators in 🇨🇭 🇪🇪 🇳🇴! Huge thanks to all co-authors and funders! @zkutalik.bsky.social @lilimilani.bsky.social @srubinacci.bsky.social @adriaan-vd-graaf.bsky.social @unil.bsky.social @estbiobank.bsky.social and many more !

Traits like disease risk can be affected differently, and in opposite ways, depending on which parent the genetic variant responsible comes from. Work led by SIB scientists @zkutalik.bsky.social & Robin Hofmeister at @unil.bsky.social/UniSanté & published in Nature👇 www.sib.swiss/news/the-imp...

🚨New preprint is out! How do genetic effects on complex traits change with age? In this work, we compare different approaches to obtain age-varying genetic effects, and show how design and modeling choices can impact the conclusions we draw. shorturl.at/17snd A thread 🧵👇

This represents a real tour-de-force by @adriaan-vd-graaf.bsky.social. It has so many strong aspects: (i) establishment of large scale ground truth data for causal inference [metabolomics/transcriptomics]; (ii) sophisticated method and (iii) biological insights through real data application.
