Research scientist at #DeepMind My research lies at the intersection of AI/Neuroscience/Cognitive Science
Joined February 2019
Happy to announce that our work has been accepted to workshops on Multi-turn Interactions and Embodied World Models at #NeurIPS2025! Frontier foundation models are incredible, but how well can they explore in interactive environments? Paper👇 https://t.co/8Q9j1VMTYv 🧵1/13

VLMs do *not* describe 3D objects consistently from different angles! But we could summarize different descriptions using a language model, right? Well… here’s what happens when an LLM merges multiple contradictory descriptions of the same object.

Since 1969 Strassen’s algorithm has famously stood as the fastest way to multiply 2 matrices - but with #AlphaTensor we’ve found a new algorithm that’s faster, with potential to improve efficiency by 10-20% across trillions of calculations per day!

Thrilled to be releasing Alchemy, a new benchmark task for meta-RL, abstract structure learning, & latent-state inference. In the paper, researchers show that Alchemy presents a formidable challenge even for state-of-the art RL agents. Game on! https://t.co/eZuPkBKuak

Face masks could be an important tool to help manage community transmission of #COVID19 in the general population, according to independent multi-disciplinary group Data Evaluation and Learning for Viral Epidemics (DELVE), convened by the Royal Society.

A good summary of many of the key thoughts behind the contract tracing APIs that @Google and @Apple are working on together.
1/ Last night, I spent some quality time with the Apple docs on the new contact tracing protocol and APIs they and Google are preparing. I'm quite optimistic about this effort. Here's why.

Good article. A few tidbits: "The systematic inability to listen to experts highlights the trouble that leaders ... have figuring out how to act in dire, highly complex situations where there’s no easy solution." ...
This, from @HarvardHBS, is the best analysis I've seen on what happened in Italy.

Today we're sharing structure predictions for six proteins associated with the virus that causes COVID-19, generated by the most up-to-date version of our AlphaFold system. We hope this contributes to the research community’s understanding of the virus: https://t.co/jW0SIA2b1F

Building our Streams app & showing we can predict AKI 48 hrs before it happens has been one of the great privileges of my life. It’s been an honour to work with so many humble and passionate clinicians @RoyalFreeNHS and @DeptVetAffairs. Here’s the human story behind our work:
Health experts believe artificial intelligence could be the answer. It isn’t the stuff of science fiction. It’s already here. @DAaronovitch meets @mustafasuleymn the brains behind the technology.

We’ve released datasets for scene decomposition & representation learning research: https://t.co/azecxAD6i5. Each image comes with ground-truth masks & features for all objects. We hope to facilitate unsupervised learning in this area, building on models like MONet & IODINE.
