Architect and researcher · Founder, Localis AI · Newcastle upon Tyne, UK

I build tools that help people examine planning decisions and public data.

I’m an architect with fifteen years of practice across Europe, the Gulf, Africa and the Americas. My research now combines urban theory, statistical analysis of planning data, and software in which an AI model proposes and a set of explicit rules checks the result.

Current projects

Your Planning Voice
In use

A tool that helps community groups draft planning objections grounded in planning policy. An AI model drafts, and rule-based checks stop anything the evidence doesn’t support. It has been used on three live cases (Carrington Moss, Lapwing Green Spaces, Mowbray BESS) and is developed with the Community Planning Alliance.

Darwinian Novelty Indicator
In testing

A tool that assesses how novel a piece of research is by comparing it with retrieved prior work. Tested on the Liu & Zhai (2026) benchmark. An earlier version received a Special Mention in the UKRI Metascience Novelty Indicators Challenge, and a calibration study with SPRU at the University of Sussex is in development.

Ariadne
Research stage

A system for generating and screening drug-repurposing hypotheses for rare diseases, with human review before any lead is used. Under a collaboration agreement with the Platt Lab at the University of Oxford, one of its predictions will be tested experimentally.

Aeolus
Tested on three estates

A decarbonisation planning tool for public-sector estates that links AI-generated proposals to established energy and carbon models. Tested on Leeds Teaching Hospitals NHS Trust, Lewisham Council Housing and Bournemouth University.

Phyora / PhyOS
Preprints

An experimental layer that monitors an AI model while it runs and halts it when its behaviour becomes inconsistent. Described in the two Constitutional Physics preprints.

Smaller experiments include a regenerative-governance model (Trinity), a music-inference engine (Aura-Echo), a Passivhaus compliance checker (Oikos) and a design for an automated discovery loop.

Research on English planning

My doctoral work audits 652 contested planning sites, drawn from 852 community submissions and cross-referenced against 65 government datasets. The main findings are:
