Damien Arnol is a data science leader and founder with 13 years of experience turning messy, high-dimensional data into actionable, deployable AI products for retail, biotech, and enterprise clients. He co-founded J2-Reliance and now directs J2R/Atombit, guiding cross-functional teams to build forecasting, anomaly detection, and large-scale recommender systems serving millions of customers and SKUs. Trained as a computational biologist with a PhD from Cambridge, he brings deep probabilistic and Bayesian modeling expertise from projects at SLAC, EMBL-EBI, IBM Research and CNRS, applied to both scientific and commercial problems. Damien combines R&D rigor with product sensibility—bridging business stakeholders and engineers to translate domain problems into mathematical models and production-grade ML systems. He also advises startups in energy efficiency, clinical AI and background checks, reflecting a knack for adapting advanced methods to diverse operational constraints. An underrated strength is his track record of scaling research-grade probabilistic models into resilient, industrial deployments.
