Origins & governance

Founders and Board.

Senscio’s current mission is a maturation of the founders’ original vision: build systems that can sense, understand, and act on complex change over time. Today that vision is expressed as Healthcare Continuity Infrastructure anchored in the home and organized around the member.

Founders

Hugh A. Stoddart, PhD, and Piali De, PhD, co-founded Senscio and developed the foundational ideas behind Scio™, Digital Twin for Health, HealthGraph, and the company’s continuing focus on persistent understanding.

In memory of Hugh A. Stoddart, PhD

Hugh A. Stoddart, PhD, was co-founder of Senscio Systems and the original architect of the Scio framework. His work on semantic representation and reasoning helped establish the foundation for Digital Twin for Health and HealthGraph.

Hugh saw how disparate signals—symptoms, vitals, medications, behaviors, and clinical context—could be represented as a unified knowledge structure that evolves over time. That insight continues to shape how Senscio maintains persistent understanding and turns changing member state into timely action.

Though he is no longer with us, Hugh’s ideas, inventions, and collaborative spirit are woven into the fabric of Senscio. Every digital twin we maintain and every day of stability we help create for a member is part of his legacy.
