In the end, we didn't find a bad place to run the #LLMHackthon for materials and chemistry kn Berlin. 🖖

It is very much fun to be back the #EMRS2025! Lots of interesting research and discussions. Sadly, we are also seeing a lot of no-shows in many sessions 😔. It is the first time I have seen this at this scale in a major conference.

We are organizing a cool workshop on research data management for PV research with NOMAD Oasis in Berlin! Registration link and tentative program: events.fairmat-nfdi.eu/event/42/ It's free, with cool people driving the digitalization of research, and there will be 🍕!

Taking some days off in Spain after a super interesting #AI4AM in San Sebastián. What a conference and what a city!

Just finished the exciting #AI4AM2025 conference in San Sebastián — learned a lot! I loved seeing recognition for people developing open-source tools for the community. Even if these tools don’t always lead to immediate breakthroughs, they’re incredibly important for enabling everyday science.

I just had the pleasure of listening to @txie.bsky.social talk about the wonders of MatterSim and MatterGen in Berlin. I think I heard correctly that for their calculations they get something of the order of 5000-10000 GPUs/CPUs in Azure for a couple of weeks! 😳🤯 Exciting times!

For all those providing reviews of scientific papers–firstly, thank you. We would not have a useful scientific literature without you. Secondly, please keep in mind that your reviews are read not only by the PIs but also students. There is no place for anger or impolite language in a review.... 1/

We wanted to make sure it is for everyone to use and also raises interest in the community to add new ways to evaluate MLIPs to gain new insights. The decision to make it open source and MIT licensed was made before we even started developing it.
