A real buzz as we kicked off our conference yesterday! An informative and collaborative day with key talks from Kathlén Kohn (KTH) and Benjamin Guedj (UCL), and a poster reception in the afternoon. Today is dedicated to exchanging knowledge and forging links with industry colleagues. More soon!

It’s been a busy first year for the Erlangen AI Hub building our team of talented postdocs! At our Year 2 Kick Off at Oxford Mathematics this week, it was great to bring the hub team together, exchange knowledge and ideas, and share some of the group’s research at the intersection of #maths and #AI

I'm grateful to share - I was awarded the MSc Marjorie McDermott scholarship by the Department of Mathematics at Imperial College London 🥳 In receiving this, I want to thank the math community at Imperial for being so inclusive and supportive of my math journey (especially as an outsider coming in).

The slides and recording should be online soon. We also plan to open source the attack dataset and publish a detailed technical report.

Thank you @satml.org for hosting a great conference in hygge-central Copenhagen! Running the LLMail-Inject competition was an incredibly rewarding experience - often in unexpected ways - so it was an honor to present it and share the results of our preliminary analysis of the attack submissions.

Back by popular demand, we have launched Phase 2 of the LLMail Indirect Prompt Injection Challenge, with an additional $6,000 in prizes! This round features a conformal-prediction-based blocklist and updated defences, including TaskTracker trained on more expressive activation signals.
