    A Cambridge PhD thesis in three research questions
    Happy new year 2026! I’ve officially passed my PhD thesis defence! Writing the thesis was a meditative and reflective period; a culmination of almost 4 years of research. As I look back, I feel...

    I'm very late to sharing this news: Deep Learning for RNA design is published in Science and chosen as the cover article! Now over 3 years ago, gRNAde started as a side-project in my CS PhD because I wanted to do something real beyond benchmarks. Its been an amazing journey

    On the citizen science platform Eterna, #AI methods matched expert human players at inventing sequences that fold into an RNA pseudoknot, a structure in which loops pair with distant parts of the same molecule. This opens a route to automatically designing RNA therapeutics,
    Each diagram is a designed RNA pseudoknot, a structure in which loops pair with distant parts of the same molecule. On the citizen science platform Eterna, artificial intelligence methods matched expert human players at inventing sequences that fold into these shapes, opening a route to automatically designing RNA therapeutics, sensors, and catalysts from scratch.

    I still remember years ago GPT4 was a (pretty poor) baseline in @nc_frey @samuel_stanton_ papers at Prescient - this is now possible with prompting, reasoning about biology and geometry!

    Many drugs work by binding to a specific target in the body and blocking or changing what it does. An important first step in the drug development process is designing a molecule that can bind tightly to its target. Traditionally, that's meant weeks or months of expert work per

    Feel kind of sad. Obviously it was said that as soon as benchmarks go public the labs train on the test set or RL on them. But this reminds me of school, rote learning for doing well in exams, etc.

    But we also took a chance to have a look at some in-the-wild scheming, reward seeking, etc. examples, and dumped it in appendix. 1) Summarizer unfaithfulness Reasoning summaries often omit important information from the original trace. Here, Opus 4.8 realizes it knows the
