Paul Knowles, the inventor and leading figure behind Decentralised Semantics, is a pioneer in semantic data infrastructure and trusted data exchange. As Co-founder and Chief Data Officer of Secours.ai, Paul is helping build the foundational data infrastructure for the AI-driven future — enabling responsible artificial general intelligence (AGI) through ethically grounded, consent-based, and interoperable systems.
He is the inventor of the Overlays Capture Architecture (OCA) — a breakthrough public utility framework for data harmonization and semantic interoperability across distributed ecosystems. OCA enables structural, definitional, and contextual alignment of data, ensuring deterministic integrity, provenance, and meaningful interoperability at scale.
Paul brings over 25 years of experience in pharmaceutical biometrics, having led or contributed to major data initiatives at companies including Roche, Novartis, GlaxoSmithKline, Amgen, and Pfizer. His unique blend of scientific depth and systems-thinking equips him to align complex data pipelines with next-generation AI and data governance architectures.
In addition to his leadership at Secours.ai, Paul continues to serve as an official editor and steward of the OCA Technical Specification. He is also active in broader digital trust ecosystems, including his work with 0PN, where he contributes to the development of next-generation transparency and security applications aligned with international privacy standards and adequacy frameworks.
