This has been a really fun project and a chance to experience, thanks to the collaborative spirit of Oskar, Stephan, Ben, Clemens, Divy, and Takashi, the best side of what science can be.

excited to announce that this January we are relocating to Yale to start a theory initiative at the Center for Systems and Engineering Immunology (CSEI): @yalecsei.bsky.social looking to hire 2 postdocs to join us in this endeavor. more details can be found here: sites.google.com/uw.edu/statp...

📢 We are announcing the Adaptive Immune Profiling Challenge 2025! Can you predict immune state labels from adaptive immune receptor repertoires? 💰 $10,000 prize pool! 🗓️ Launches Nov 5 on @kaggle.com More Info: uio-bmi.github.io/adaptive_imm...

The final version of our "Thrifty" paper is up now: elifesciences.org/articles/10... . We were motivated to fit wide-context mutation models based on previous analyses showing "mesoscale" effects and a position-specific effect. But, how to avoid exploding the number of parameters? 🧵

I'm stoked to have this long-term and highly collaborative effort out in the wild. We present an experimental evolution system to quantitatively study the rapid evolutionary dynamics of B-cell affinity maturation. These evolutionary mechanisms underpin antibody responses and immune memory formation.

Thrilled to announce that our work (w. with fantastic @neher.io and Liam Shaw) has been published on Molecular Biology and Evolution! 🎉 academic.oup.com/mbe/advance-... Are you curious about how fast the genome of E.coli evolves structurally (gains, rearrangements...) ? 🧬 A summary thread [1/N]🧵

After a long and winding odyssey, excited to finally drop anchor in open-access waters. This preprint shows how neutral allele frequency time series can illuminate disease transmission rates between communities— key for epidemic fore- & backcasting. medrxiv.org/content/10.1... 🧵

Curious about generative modeling for T and B cell receptor repertoires and its role in understanding immune system diversity? Watch my talk here youtu.be/HVUYG-UmRH8?.... Thanks to the @airr-community.bsky.social and @victorgreiff.bsky.social for the opportunity to share our work!
