An AI Researcher in the Cathedral of Molecular Biology How we designed catalytic RNA functions, and what I learned holding a pipette at the MRC Laboratory of Molecular Biology.

I wrote some personal reflections about being physically embedded in a world-leading molecular biology lab @mrclmb.bsky.social, learning to communicate with experimentalists, back-breaking wet lab work, scientific rigour, and skin in the game!

Excited to release the fully open-source code for gRNAde - our wet-lab validated, generative AI framework for 3D RNA inverse design 🚀⭐️

I pride myself on open-science & this is probably the most intense release I've done!

Pre-pore and cis pores formed by full length perforin-2 during antigen escape from early phagosomes

Pre-pore and cis pores formed by full length perforin-2 during antigen escape from early phagosomes

Time for a new pre-print! How do dendritic cells control pore formation in their own endocytic compartments?

Our work shows that the unique transmembrane anchor of perforin-2 does not protect DC membranes, but instead it enables antigen escape during cross-presentation

Introducing gRNAde: our own little "AlphaGo Moment" for RNA design! 🧬🚀

Unlike proteins, RNA design has long relied on "wisdom of the crowd" (human experts) or the slow crawl of directed evolution — gRNAde changes that! 🧵👇

Rewriting the language of life: Jason Chin’s group in the LMB’s PNAC Division have synthesised E. coli with just 57 codons instead of the usual 64.
Syn57 required 101000+ codon changes & represents a bold step towards programmable life.

Excited to share our latest work! We found transcription factor SPT6 and phosphorylated Pol II CTD help recruit U1 snRNP to elongating Pol II, allowing efficient co-transcriptional splicing.

In the paper, we investigate RNA polymerase ribozymes and their ability to perform rolling circle synthesis (RCS).

We previously showed that RCS is possible, though inefficient. Now, we use cryo-EM and identify a network of unexpected structures (see movie) which affect RCS.
