Cheminformatician & data scientist — machine learning for drug discovery.
I build ML models and tools for drug discovery (molecular property and ADMET prediction, DNA-encoded library screening, generative de novo design, and ultra-large chemical space search) and ship them as production systems used by medicinal chemists on live projects. PhD in chemistry (Cambridge), with hands-on synthetic research experience.
- Research Software Engineer at OpenADMET (Open Molecular Software Foundation) — building the blind-challenge infrastructure behind the PXR and CYP challenges (4,000+ submissions from 400+ participants), now open-sourced and adopted by other groups.
- Technical blog: jonswain.github.io — tutorials on cheminformatics and machine learning.
- Contributor to the OpenADMET blog.
- Invited talk: "DIY AI: Open-source AI for drug discovery" — University of Auckland 2026 Gibbons Memorial Lecture series.
