We have funding for SWARM-E, a long-term group at @zif-bielefeld.bsky.social! I'll be leading with co-leads @marinapapa.bsky.social @joefresna.bsky.social to better understand collective behaviour across biological and artificial systems. First workshop 2027... www.shoalgroup.org/swarm More soon!

Thank you, @gyllingberg.bsky.social, for all your hard work on the model and the manuscript! This is one of my favorite results coming out of the lab. The model has a lot of potential, I'm looking forward to continuing to work on it with you :-)

📢Coming up, workshop at #Behaviour2025 on our swaRmverse package! 🗓️Tue 26/8, 13:10–14:40 💻Theory & R practical (feel free to bring your data) 🎯Discussion on comparative analysis & metrics 🙏Come & recommend features for version 2.0! 👉RSVP on the app More info: behaviourindia2025.in/workshops.html
Poster with the workshop's title on the left: "Into the Swarm-Verse: a new R package to analyse trajectories of animals on the move". The speaker's name is indicated as 'Marina Papadopoulou' and the date/time as "Tuesday 26th of August, 2025, 1:10-2:40 PM.". On the right there is an example of a swarm space (points of different colors in 3 dimensions), the pictures of the animal groups that they represent, and the logo of the R package. At the bottom, there is the reference to the paper: "Papadopoulou M., Garnier S., & King A.J. (2024) swaRmverse: An R package for the comparative analysis of collective motion.
