Our latest work on shape-programmable tissues is out in @science.org. By positioning topological defects in cellular nematics, we encode frustrated 2D force fields that relax into predictable 3D shapes. Collaboration with Marino Arroyo’s lab, led by @pauguillamat.bsky.social at @ibecbarcelona.eu.

*Sharing code for research publications*
Here's the process that I've ended up with, through various collaborators like Robert Forkel, @simongreenhill.bsky.social , Stephen Francis Mann and others.
Not perfect perhaps, but works pretty ok.
A student asked, so I made this illustration.

Very happy to announce that I will be joining the Faculty of Biology & @cibss.bsky.social at @uni-freiburg.de as an Emmy-Noether funded group leader.

We will tackle the molecular and genetic basis of developmental timing and size control using diverse Oryzias species. We are hiring at all levels !

All key features at a glance – with the #tidyplots cheatsheet 🤩

Who needs PowerPoint when you have Quarto and @emilhvitfeldt.bsky.social's extensions?!

I wanted to make an image-heavy presentation. Usually, I'd reach for Keynote.

But Emil shared quarto-revealjs-editable, which let me stay in Quarto land 🥰 Thanks, Emil!

Imputation integrates single-cell and spatial gene expression data to resolve transcriptional networks in barley shoot meristem development - Nature Plants Spatially resolved gene expression during barley development was done by integrating an scRNA-seq dataset from cells with unknown position with spatial transcriptomics. This dataset is publicly availa...

We recently published a first story on combining spatial and single cell transcriptomics in barley (see here: www.nature.com/articles/s41...)

Lets go for the next level now, i.e. understanding gene networks and barley meristem development in 4D!

Announcing the publication of TAIR12: Consult the fully reannotated genome on the European Nucleotide Archive - Phoenix Bioinformatics TAIR (The Arabidopsis Information Resource), together with our nonprofit host Phoenix Bioinformatics, is pleased to announce the public release of TAIR12

🎉📣 #TAIR12, the latest reannotation of the Arabidopsis thaliana genome, is now available under accession number PRJEB100887 on ENA and NCBI!

Thank you all the volunteer researchers whose hard work has made this possible!

dplyr 1.2.0 dplyr 1.2.0 fills in some important gaps in dplyr's API: we've added a new complement to `filter()` focused on dropping rows, and we've expanded the `case_when()` family with three new recoding and re...

dplyr 1.2.0 is out now and we are SO excited!

- `filter_out()` for dropping rows

- `recode_values()`, `replace_values()`, and `replace_when()` that join `case_when()` as a complete family of recoding/replacing tools

These are huge quality of life wins for #rstats!

New preprint!
SOSEKI polarity proteins are mechanoresponsive integrators linking growth and tissue mechanics during lateral root formation. Their polarity marks growth boundaries and reorganises in response to mechanical alterations —reshaping how we think about axis formation.

📢 It came to my attention that due to more restrictive recent regulations, our colleagues in Japan have immense difficulties shipping (receiving?) seeds by mail. Apparently, having someone carry them is the most reliable option. Anyone travelling soon from 🇯🇵 to 🇪🇺?

Our work on mapping the dynamics of phospholipids during lateral root formation is now published in @jxbotany.bsky.social We show that PI(4,5)P₂ plays a key role: targeted reduction in pericycle promotes LR development.

Our new paper is out!
1/14 How does an organ rebuild its shape after injury? It's not just about making new cells, but aligning them in the right direction — like bricks shaping a structure. We show that it's all driven by Cell Geometry!
