IVHM & system architecture.

Integrated Vehicle Health Management is what turns a sensor network into a decision-support system. I work across the full IVHM stack — from data acquisition through diagnostics, prognostics, and asset condition assessment — for platforms where safety and availability are non-negotiable.

Physical twin, data twin.

A live B737-800 IVHM digital twin. The 3D pane on the left is the physical asset; the schematic on the right is the data twin, rendered with real ATA-coded sensor positions across air-data, engine, fuel, hydraulics, ECS, gear, and structures. Telemetry flows: sensor → DAU (data acquisition unit) → AIMS (aircraft information management system) → SATCOM uplink → ground IVHM service.

Designing a health system?

Whether it's an airframe, a fleet of pumps, or a process plant, the IVHM principles transfer. Let's talk about what your platform actually needs to know.
