Emile Mathieu is a machine learning researcher with 11 years of experience bridging rigorous academic research and industry impact, currently working at Xaira Therapeutics after postdoctoral roles at Cambridge and Oxford. He holds a PhD in Statistics/Machine Learning from Oxford and advanced mathematical training from École Normale Supérieure and École des Ponts, bringing deep probabilistic and applied-math expertise to real-world problems. Emile has hands-on contributions to open-source probabilistic programming—implementing and testing Particle Marginal Metropolis-Hastings in the widely used Turing.jl—demonstrating both theoretical skill and practical software engineering. His background spans ML research internships at Facebook AI and applied roles improving online bidding and transport-data analysis, showing an ability to move from models to deployed systems. Colleagues describe him as a researcher who pairs statistical rigor with a pragmatic focus on reproducible, test-backed implementations.

Contributions summary:Emile implemented and tested Particle Marginal Metropolis-Hastings (PMMH) sampling within the Turing.jl probabilistic programming framework. Their contributions included the creation of PMMH-related files, defining the PMMH sampler, and integrating it with existing sampling techniques such as SMC. The user also added tests to validate the PMMH implementation and incorporated features for proposals and support checking.
