I’m starting at the Hubrecht Institute at a new group leader from September. I will be hiring a PhD student through the PhD program ⬇️ If you, or anyone you know, is interested in theoretical biophysics, I will be very excited to hear from them — please send inquiries to my ISTA email for now :)

New paper out in Nature Physics: we show that the embryonic epigenome forms according to universal physical rules. www.nature.com/articles/s41...

Sometimes publishing interdisciplinary work is difficult but if you absolutely want to make sure that even general science journals don't find an Editor, try analyzing public health data through physics-inspired data parameterizations.

How does human body surface area scale with size? Using 3D laser scanning and DXA in 106 adults, we found BSA scales linearly with height and mass. No power laws needed, and lean/fat/bone breakdowns don’t really improve predictions. journals.physiology.org/doi/full/10....

In February, I had the great pleasure of giving a talk at the Gulbenkian Institute for Molecular Medicine about our work on modeling human physiology to improve patient treatment. A fabulous visit and many great questions from the audience. gimm.pt/news/modelin...

It is with great sadness that the University shares the news of the death of Professor Sir John Gurdon, founder of the @gurdoninstitute.bsky.social Read our tribute to the visionary Nobel Laureate and watch an interview from 2012, just after he won: bit.ly/4mM8o3r

🚨Job alert in theory/math devbio 🚨 I’m currently advertising postdoc positions to join my group. We’re building reaction-diffusion models to understand some of the crazy things embryos can do. We are based in a beautiful part of Scotland :). Please share! www.abdnjobs.co.uk/vacancy/rese...

I am thrilled and honored that—alongside my work as a researcher in industry—I have been appointed Adjunct Professor at @penningtonbiomed.bsky.social. I will be working with Dr Steven Heymsfield and Dr Peter Kotanko in the area of human body composition and metabolism.

New preprint: How do cells measure time? In human development, pluripotent epiblast cells pause for about two weeks before differentiating into more specialised cell types. We show that this timing is controlled by a transcriptional clock that works like an hourglass. www.biorxiv.org/content/10.1...

Developmental timing differs strikingly between mammals. All embryonic and some placental lineages emerge from the pluripotent epiblast in a temporally defined sequence, lasting about two weeks in the...

New preprint: are deep neural networks just complicated curve fitters or can they show emergent behavior that is independent of the data? We show that training deep neural networks gives rise to emergent weight morphologies independent of the training data. arxiv.org/abs/2501.05550

I'm always amazed by hallmarks of universality in social systems. This linked paper by Pal et al. shows how a minimal model of random voting behavior can reproduce margin distributions across many countries. They suggest that deviations from this universality might hint at electoral malpractices.

Interspecies scaling laws (allometries) are a fascinating phenomenon. Here we investigate allometric scaling relationships of quantitative cardiomyocyte properties across different mammalian species. doi.org/10.1242/jeb.... (w/ Tanja Kloock and Christian Mühlfeld)

If you run your own domain, you can change the handle of your Bluesky account to your domain name. This provides a bit of an identity verification. See here: bsky.social/about/blog/4... Note that I am not an IT security expert and can't speak to any security issues that might arise from this.

Teaching statistical physics this term. If things get difficult, we get help from super heroes like Mr T (who can relate macroscopic variables) or S-man (who can derive them micrscopically). There is also a villain called Boltz-man who has the habit of creating super-large numbers.

In this collaboration with Ben Simons' and Shosei Yoshida's lab, we propose a minimal mechanism for the intricate spatiotemporal dynamics of the spermatogenic wave. Congratulations to Toshiyuki Sato (experiment) and Yuting I. Li (theory) for their outstanding work! www.biorxiv.org/content/10.1...
