I’m excited to have our perspective on virtual cells out.

This is very worth reading to see just how hard AI safety is going to be as these systems continue to get more powerful. The AI safety community has long emphasized how hard reward specification is: here’s a real world instance of a paper clip maximizers. openai.com/index/expand...

Expanding on what we missed with sycophancy

A deeper dive on our findings, what went wrong, and future changes we’re making.

I’m very excited for this workshop on Generative AI for Biology workshop that we’re hosting at UCL in London. It hybrid so you can attend virtually or in person (limited spots so reach out).

Excited to share that our work on ''Inference Set Design for Biological Data'' @valenceai.bsky.social was accepted at ICLR25! 🚀 The paper is available now on arXiv, and we're looking forward to share and discuss the potential of active learning in AI for drug discovery this April in Singapore! 🧬 📊

I’m super excited that Learning Meaningful Representations of Life is back for ICLR 2025. We have a fantastic group of speakers lined up and there’s never been a better time to think about what makes a “meaningful” representation and how to learn one. Consider submitting!

Finishing off NeurIPS right: a swim at Jericho Beach. Air temp: 5°C, water temp: 6°C. A very effective way of icing a broken ankle.

I’ll be at NeurIPS next week (hobbling around on crutches with a broken fibula). Reach out if you’d like to talk causal representation learning / virtual cells / active learning. Also - I’m looking for phd students, so if you’re applying for phds in these areas, reach out !

We're hiring two interns and a full time post in the Valence labs London office. If you're interested in causal inference / generative models / latent variable inference and how to use these ideas to impact real world drug discovery programs, consider applying: job-boards.greenhouse.io/valencelabs
