A research agenda.

My research lives at the intersection of optimisation, diagnostics, and decision-making for complex engineering assets. The PhD established the methods; the ongoing work extends them into domains and ventures where the cost of a wrong signal is highest.

The central question

How do we make better decisions when signals are incomplete, noisy, and expensive — and how do we know which signals are worth paying for in the first place?

Three threads, one method.

All of my research uses multi-objective optimisation as its language. The threads differ in what they optimise over — sensors, decisions, or whole asset architectures.

01

Sensor optimisation

What to measure on a complex asset, where to measure it, and how to score what each sensor contributes — formalised in MOSOF and the Normalised Diagnostic Contribution Index (NDCI).

02

Diagnostic decisions

Once the signals are in, how do we turn them into actions a stakeholder can defend? Frameworks that surface uncertainty and trade-offs honestly rather than hiding them in a black-box label.

03

Stakeholder-aware design

An OEM, an operator, and an MRO weight the same problem differently. Methods that make those weightings explicit and let the right answer for each be different — without re-running the analysis from scratch.

From method to application.

Each research output has a direct commercial translation. The methods are not academic curiosities — they are the foundation of consulting engagements, software ventures, and the reason the PhD was worth doing.

Research output

NDCI — Normalised Diagnostic Contribution Index

An information-theoretic scoring function that ranks every sensor in a network by its unique contribution to distinguishing fault states.

Commercial application

The core scoring engine in the Diagnostic Coverage Audit consulting offer and the Sensorry sensor-network design tool.

MOSOF — Multi-Objective Sensor Optimisation Framework

A genetic-algorithm search over sensor configurations across multiple competing objectives — cost, coverage, reliability, weight — producing a Pareto-optimal frontier of defensible options.

Commercial application

The optimisation engine in the Custom Optimisation Framework consulting offer, the Sensorry tooling, and the foundation of the engineering code artefacts.

Multi-objective by default.

Real engineering decisions never have a single objective. Performance fights weight, reliability fights cost, accuracy fights latency. Forcing a single scalar out of that pretends a trade-off doesn't exist; surfacing the Pareto front shows the trade-off honestly and lets a human pick.

The methods are search-based — NSGA-II-family genetic algorithms over carefully encoded candidate spaces — and the validation is empirical, not just analytical: every framework gets tested on a real reference system before it ships.

  • 01Encode — what are we choosing between, and what objectives does the choice trade off?
  • 02Search — multi-objective evolutionary algorithms over the candidate space.
  • 03Score — diagnostic contribution, not just dominance, when the candidates are sensors.
  • 04Surface — Pareto front plus a knee-point recommendation, with explicit trade-offs for stakeholders.

If your team is grappling with sensor selection, diagnostic-system design, or decisions under expensive uncertainty — in academia or industry — I'd be glad to discuss whether there's overlap.
