Nice @physicell.bsky.social shout out at the European Society for Spatial Biology #ESSB2026! Linking modelling with spatial biology is definitely an exciting frontier for these datasets 🤩

I'm at #ESSB2026, as you can tell by these stairs! My flash talk is tomorrow, but I'll actually be presenting my poster today! So why don't we agree that you'll find me at Poster 45 this evening, and then I'll persuade you to come and see it in the Computational Spatial Bio session tomorrow. Deal?

MuSpAn will be at #ESSB2026! Both @josh-moore.bsky.social and I are discussing new mathematical methods that are making their way into the package, during the Computational #SpatialBiology session flash talks on Tuesday - or come and find us with any questions! Paper: doi.org/10.1038/s414...

Happening in SR11.33 after the coffee break! If my thread below isn't incentive enough, the preceding talk is modelling artificial insemination of Water Buffalo - bet you haven't been to any other talks on that this week #EMCTB26

Joshua Bull @joshuabull.bsky.social · 14/07/2026
Are you at #ECMTB26? Do you like topology? Do you like the idea of topological data analysis, but worry that it's too computationally expensive and that you wouldn't be able to interpret the output? If you said "Yes" to any of these, you might like my talk at SR11.33 at 11:50am on Wednesday =)

In 2022 Fantasy Premier League winner @joshuabull.bsky.social made his World Cup predictions. They were okay, but no cigar. However, in the intervening four years he has really honed his mathematical skills. Now he is 100% confident he's found the secret sauce.

The World Cup is almost here and everyone has an opinion about likely winners. But being mathematicians, we have insisted on looking at the data, and we think we have found the secret to predicting results. @joshuabull.bsky.social is our analyst in the studio.

Yes, my wedding has a website Yes, I have also included modelling of the expected temperature on the day Yes, I did this by fitting a Bayesian model to 45 years of temperature data Yes, the wedding website has an easter egg with a little link to find a writeup of how I got the numbers
Text on the website answering how hot it will be: 80% chance of between 21.0 and 31.5 degrees C.Some of the maths of the model fit on the easter egg page (there's SO MUCH MORE LOL I AM A NERD), including a little linear fit with the CI shown.
