Small personal update: very pleased to be in Singapore next week to present 2 spotlight papers at ICLR 2025 on AI for molecular design!! 🇸🇬

DM me if you want to meet up and chat about AI for bio, drug discovery, science policy or just chat about aviation!!!

16/ What’s clear is that getting data and compute right is essential—not just for breakthroughs in science but for keeping the UK competitive globally.

Here’s hoping this plan gets the funding, leadership, and focus it needs to succeed!

Happy to chat about any of this.

15/ Side note: UK universities could supercharge their AI teaching by embracing industry expertise (where the real knowledge is)

I teach a course at Cambridge led by a DeepMind researcher, and it’s the most popular in the department.

Charlie Harris @harrisbio.bsky.social · Jan 13

14/ US universities do this well with CS minors, which foster computational literacy across disciplines.

The UK could adopt similar models to produce scientists who are not only domain experts but also skilled at applying AI tools to their fields.

Charlie Harris @harrisbio.bsky.social · Jan 13

13/ The plan has solid ideas on AI skills, but it's not *just* about creating more "AI graduates." We need to train domain experts in the natural sciences to understand and use AI effectively.

Almost all scientists should know neural networks as well as they know Excel and stats

Charlie Harris @harrisbio.bsky.social · Jan 13

12/ Another standout: the plan proposes an internal headhunting team within the UK Government to attract top global talent to AISI, the UK Sovereign AI Team, and UK-based companies.

Will they also have the power to fast-track visas? From experience, i hope so....

Charlie Harris @harrisbio.bsky.social · Jan 13

11/ The UK Sovereign AI Team could be a great connector of
-Public institutions creating scientific datasets
-Industrial labs capable of training models on those datasets

This sort of collaboration could really unlock breakthroughs in science

Charlie Harris @harrisbio.bsky.social · Jan 13

10/ The plan’s proposal to create a UK Sovereign AI Team is great. This unit will partner with private and academic sectors to back national champions and remove roadblocks in AI, with a strong focus on AI for science and robotics.

Charlie Harris @harrisbio.bsky.social · Jan 13

(Usual reminder that AlphaFold3 was trained for 120k+ GPU hours... this is multiple times more than the whole compute budget of my lab this year)

Charlie Harris @harrisbio.bsky.social · Jan 13

9/ Another question: who will the AIRR programme directors work for? UKRI? ARIA?

Will they be empowered to deploy large amount of compute into highly productive groups at the cutting edge?

There is no point in this if it means everyone only gets a few GPU hours each.

Charlie Harris @harrisbio.bsky.social · Jan 13

9/ One question: will these AIRR programme directors also decide how funding is allocated for data generation?

For scientific initiatives, compute and data strategies are deeply interconnected. Ideally, the same person would oversee both to ensure alignment.

Charlie Harris @harrisbio.bsky.social · Jan 13

8/ Another standout is the creation of AIRR programme directors—mission-focused individuals with autonomy to strategically allocate compute to high-potential projects.

A kind of "Compute Czar" role, this could significantly accelerate progress on big bets in AI for science.

Charlie Harris @harrisbio.bsky.social · Jan 13

7/ However, there’s a risk of duplicating efforts where existing world-class institutions, like the EBI managing the PDBe, are already doing excellent work.

Not every problem needs to fit into a National Data Library-sized™ hole. Let’s build on what we already have!

Charlie Harris @harrisbio.bsky.social · Jan 13

6/ People often say, "Big Pharma has lots of data!"—but much of it is unstructured and sparse, making it unsuitable for deep learning.

The plan acknowledges this challenge and recommends creating better infrastructure and incentives to make datasets AI-ready.

Charlie Harris @harrisbio.bsky.social · Jan 13

5/ That’s why I’m thrilled to see the plan emphasise strategic data initiatives:
-Identifying high-impact datasets
-Improving data quality
-Incentivising researchers and companies to unlock and curate datasets

These efforts will make sparse, unstructured datasets better for AI

Charlie Harris @harrisbio.bsky.social · Jan 13

4/ If we want breakthroughs beyond protein folding, we need to address data gaps across science.

AlphaFold was made possible by sustained investment in protein structure data.

Similar long term commitments are essential for other fields like materials and climate science.

Charlie Harris @harrisbio.bsky.social · Jan 13

3/ AI breakthroughs like AlphaFold wouldn’t be possible without decades of work on datasets.

e.g., AlphaFold was trained on protein structures from the Protein Data Bank (PDB), which took 50+ years and ~$20 *billion* to create.

This is the kind of foundational effort AI needs.

Charlie Harris @harrisbio.bsky.social · Jan 13

2/ There’s a lot to like in this plan:
- Expanding UK AI compute capacity by 20x
- Establishing AI Growth Zones
- Building up AI talent pipelines

But as a scientist, what excites me most is the report’s focus on **data**—an area we really need to get right.

Charlie Harris @harrisbio.bsky.social · Jan 13

1/ Just read through the Matt Clifford AI Action Plan now.

Tl;dr: it's great but here are a few things that stood out to me as someone interested in AI for Science and sovereign compute and data capability.

A thread: 🧵

A common issue I see in ML, both from ML "experts" and "users", is overly optimistic assumptions.

"experts" (people designing algs) usually assume the data is very simple

"users" (people using algs) usually assume that algorithms are more robust than they really are

Conclusion: always be careful!

Added NewCo Kerna Labs, a new AI-first mRNA payload design company founded by former Moderna CSO with $6M in seed.

Also added new Cradle Bio series B worth $73M

Now I can share external links without the posts being down regulated - I thought it would share this again!:)

I have compiled a list of now 100+ companies in the 'TechBio' space into a fully open database for the community.
