Summary

Rockstar🎓
Top SchoolRaphael Sonabend-friend is an Associate Director and machine learning expert with a PhD in statistics and over a decade of experience spanning data analysis, consulting, and open-source leadership. He has influenced high-stakes public health decisions through contributions to UK COVID-19 modelling and led multi-million-pound data science portfolios at Wellcome, taking projects from ideation to deployment. As founder of OSPO Now and previous founder of Codort, he blends technical product-building with open-source program strategy, authoring and editing specialist ML texts such as Applied Machine Learning Using mlr3 in R. At NICE he now shapes practical frameworks for evaluating AI in health technology and real-world evidence, combining hands-on code testing with policy and governance design. His background bridges academia and industry—publishing, building reproducible tooling in R/Julia, and advising genomics and health organisations—making him adept at translating complex models into usable, compliant systems. An unexpected thread: he pairs deep survival-analysis research with community-focused open-source stewardship, so his work often moves both science and practice forward.
