Great to see this out there! We infer the evolutionary pathways behind patterns of AMR in Klebsiella across 102 states, finding globally consistent principles, state-specific deviations (and covariates), and validating evol predictions with new genomes. biorxiv.org/content/10.1... 1/

Celebrating grant award with a mountain run! MitoPhyto, a FRIPRO project, will combine modelling and microscopy to explore mitochondrial and mtDNA maintenance across non-bilaterian multicellular eukaryotes. Opportunities to come to Norway: please see next post

Gratulerer med dagen alle sammen! (non-Norway-based folks, happy Norwegian Constitution Day!)

Glad to share this review, which takes a narrative approach to explore mechanisms governing cytoplasmic inheritance. It highlights exciting advances in the field, while also pointing to the many open questions that remain. Have a read here: doi.org/10.1093/plph...

Had a brilliant time at the 54th Jírovec’s Protozoological Days in Frymburk. Amazing organisms, amazing science, lots of exciting organelle work. Beautiful setting too! Thanks to all www.chromera.org/konference/5...

May trails on the way to the final Applied Statistics lecture of the semester!

View from the office as summer approaches

Exciting permanent(!) #JobAlert for a #botanist to work in Bergen, Norway 🧪 PhD required, language proficiency required within two years. Apply by 25 April. #Ecology #Restoration #Botany

Out today: Exciting intermediate between endosymbiont and organelle identified! Endosymbionts in Angomonas deanei lost nearly all bacterial cell division genes. Instead, we identified a host-encoded protein, ETP9, that became specialized for endosymbiont division. 1/2 www.science.org/doi/10.1126/...

Projector broke today, so a good old-school blackboard lecture on an intro to GLMs!

Watching the US take a wrecking ball to science 💔 🤯 Reminder of the importance of doing science in the open. Put data, software, resources in public domain, where no single govt can erase them. This is our collective knowledge. Distributed data systems are essential. www.nature.com/articles/s41...

Great to see this out in final form! www.nature.com/articles/s41... Continuous buildup of single-cell-specific mtDNA mutations throughout ageing, and their links with health. Mitos, scRNA, scATAC, models, ER, neuro... a smorgasbord of science! Congrats all! @syssig.bsky.social

Started likelihood-based approaches for model selection in STAT200 today, one of my favourite things (and behind many of our research projects)! Combined with likelihood-free methods, my claim is that this is how we turn modelling (not really falsifiable) into science (testing hypotheses with data)

A classic to celebrate this evening's proposal submission. If you haven't heard this before, I recommend sticking with it, it's somewhat unlikely you've heard a song like this before! www.youtube.com/watch?v=rxjE... Lyrics www.metalkingdom.net/lyrics-song/...

Some shots from wintery commutes in 2025!

Nice group meeting today, celebrating exciting new positions and discussing the diverse ways we do science with data! Thanks all

We've been thinking a lot about "accumulation models" lately -- inferring how systems accumulate features over time. May be mutations in a tumor, characters in evol bio, gene losses in oDNA. Here's an instance of the well-known Mk model that captures this picture academic.oup.com/bioinformati... 1/

This year’s Mørketidens Mattemøte once again brought mathematicians from across Norway and the Nordic countries to @uitnorgesarktiske.bsky.social for two inspiring days of idea exchange and new connections. Thanks to Tromsø Forskningsstiftelse and Trond Mohn forskningsstiftelse for the support !

Getting back on the reading after a busy semester start. These look exciting in the world of organelle genomes! www.biorxiv.org/content/10.1... www.biorxiv.org/content/10.1... (congrats @sloanevolab.bsky.social et al.!) www.biorxiv.org/content/10.1... (congrats @wallaceucsf.bsky.social et al.!)

Advanced machine learning methods are cool, but here's why I'm excited to be teaching classic STAT200 (applied statistics) this spring! Featuring some of Bergen's mountains youtu.be/IdC7SzPV6EU

First skitur of 2025, chasing the sunrise

Happy new year! Write down 1 once, 2 twice, 3 three times, etc. 122333444455555.... Once you get to forty-five 45s, sum up all the digits you've written down. It's 2025 (45×45). 2025 is the only number except 1 for which this happens. Here's more 2025 fun www.numbersaplenty.com/2025

A new biosensor is born 👼 The NAPstar family of genetically-encoded sensors for live NADP redox monitoring🔋🪫 Jointly with the Morgan lab & @riemerlab.bsky.social we looked in vitro, in yeast, plants & mammalian cells 🧪🦠🧫🌱 Where to go next? @naturecomms.bsky.social doi.org/10.1038/s414...

We're excited to announce a generous $3.3M grant from the Bill & Melinda Gates Foundation.

Happy to share our collaborative review on the expansion of the MutS gene family in plants and all the cool (and in some cases still unknown) roles of these genes. Now published in @theplantcell.bsky.social! doi.org/10.1093/plce...

Second paper from the lab out today (woohoo!). This one led by Rachael DeTar. Check out what happens to mito+plastid translation machinery in plants that have lost photosynthesis! Published in @pnas.org: www.pnas.org/doi/10.1073/... Also available on bioRxiv: www.biorxiv.org/content/10.1...

First commute run for a while, following some illness, travel, and language exams. Beautiful wintery vibes throughout over the Bergen mountains!

Have had some good chats recently about pivoting to non-profit and society journals. A point to share/underline is that such options exist across the "prestige" spectrum. Some examples in the image. All heavily subjective of course; would love to hear thoughts from others!

What's the biggest sofa you can move round a right-angled corridor one metre wide? One of my favourite "easy to ask, hard to answer" maths problems has a [claimed] solution after many, many decades (!) of work arxiv.org/abs/2411.19826 (GIF from blogs.ams.org/visualinsigh...)

Wonderful time visiting and talking at Oslo Natural History Museum www.nhm.uio.no ! A childhood dream come true to present science in such a cool environment. Looking forward to more exploring today!

RTs much appreciated... would love to reach both AMR and biomath folks! "Evolutionary accumulation modelling in AMR: machine learning to infer and predict evolutionary dynamics of multi-drug resistance" arxiv.org/abs/2411.00219 We think EvAM methods have some potential in AMR. 🧵
