I design artificial intelligence systems that hold by structural constraint, not by instruction.

Fifteen years of urban masterplanning and spatial systems design across Europe, the Middle East, Africa, and the Americas taught me that complex systems cannot be governed by behavioural training alone. I develop Constitutional Physics and Aitiopoietic Cognition — a general-purpose, neurosymbolic methodology that binds generative language models to deterministic mathematical rules, physical engines, and verified legal frameworks.

Across eight distinct domains, this architecture makes misalignment, hallucination, and structural failure thermodynamically expensive or code-level impossible.

Methodological Foundation

Constitutional Physics

Standard reinforcement learning (RLHF) produces allopoietic systems that learn what aligned output looks like without possessing an existential stake in structural validity. The Aitiopoietic Methodology re-introduces thermodynamic coupling, turning structural coherence into an operational condition of existence. The LLM operates as a thermometer, not a judge: domain axioms, statutory laws, and physical equations are encoded as hard-coded selection pressures that execute after generation. Unrecoverable structural contradictions trip an automated, inference-layer Constitutional Halt.

Empirical Foundation

Audit of English Planning

A two-year computational-statutory audit of the English statutory planning system: a federated spatial pipeline cross-referencing contested planning sites against 65 live open-government spatial layers. The canonical cohort is a locked, de-duplicated N = 652 contested sites, drawn from a gross harvest of N = 852 grassroots campaigns through a seven-stage sample-flow attrition funnel.

01
The Defensibility Gap — two axes
Statutory protection does not scale uniformly with wealth. Ecological shields skew affluent: Ancient Woodland buffer proximity returns OR = 4.88, p = 8.4 × 10⁻⁶. Built-heritage protection runs the opposite way: Heritage at Risk skews deprived at OR = 7.54, p = 3.2 × 10⁻⁵. The composite with the flood term removed holds at p = 0.0017. What the gap measures is a disparity in affluence-linked, preventative shields specifically — not statutory protection as a single category.
02
Speculative capital concentrates on the best farmland
Grid-scale energy capital intersects provisional Best and Most Versatile agricultural land at 72.7%; strategic residential sprawl at 54.2%; logistics at 50.0%; urban infill at 46.6%. Pearson's χ² on the 4 × 2 contingency table: χ² = 12.72, df = 3, p = 0.0053.
03
Ecological data scarcity peaks in the middle
Data deserts are non-monotonic across deprivation. 34.9% of contested sites sit in an Ecological Data Desert (fewer than 5,000 historical records within 1 km), peaking at 47.4% in IoD2025 decile 6 — the commuter-belt fringe. No detectable class difference overall: p = 0.34.
04
The state's own data infrastructure fails
Three services, three distinct failure modes, one vantage point, one day. HM Land Registry INSPIRE: scripted requests refused at the Cloudflare edge (403); a manual browser capture returned Service WFS is disabled. HSE Major Accident Hazard Pipelines: no national service found by the pipeline. Coal / MRA: configured addresses invalid (HTTP 200 carrying an "Invalid URL" error); the layer is discoverable through the public catalogue and answers correctly.
05
Labour constituencies carry the compound vulnerability
Of the 47 canonical Triple-Jeopardy sites (IoD2025 ≤ 3 and IMED ≤ 3), 41 (87.2%) fall in Labour-held constituencies versus 41.8% of non-TJ sites — a disparity of +45.4 pp, with OR = 9.51 [3.98, 22.73], Fisher's exact p = 7.4 × 10⁻¹⁰. Robust under whole-thesis Bonferroni.
06
The outcome is a clean null
Of 606 decided sites with a resolved NBN count, 546 permitted and 60 refused — a 90.1% developer success rate. Data-desert sites show no detectable difference in permission (OR = 0.98 [0.56, 1.71], Fisher p = 1.00); unresolved corporate ownership OR = 0.75, p = 0.34. The consultation-stage asymmetry does not translate into a detectable difference in the binary permit/refuse outcome — bounding the thesis to the consultation side.

Systems Built

Eight Substrate Proofs

The methodology's generality rests on empirical validation across eight unrelated, high-stakes application domains — each constructed from first principles to demonstrate substrate-independent governance.

Your Planning Voice — Civic Planning Defence
Live · CPA Network
A constitutional platform for UK statutory planning defence. Ingests 54 live UK government data feeds (DLUHC, Natural England, Environment Agency, Historic England) and runs developer documents through 13 Zod extraction schemas. Enforces a 4-validator forensic manifold — the Case-Law Factbook (including R (Finch) [2024] UKSC 20), a 23-rule forbidden-string corpus, an Archetype × Ground matrix, and a Citation Provenance validator — with an automated hard stop at forensic score < 40.

88–93% independent legal verification across live cases: Carrington Moss, Lapwing Green Spaces, Mowbray BESS.

Partnership with the Community Planning Alliance (700+ UK community organisations), Planning Aid England, CPRE, and the Better Planning Coalition.

Integrity-proven via a 31-assertion watchdog suite with zero TypeScript errors across 25k lines.

Darwinian Novelty Indicator — Metascience
Pilot · MetaROR / SPRU
A retrieval-grounded, multi-judge instrument that evaluates genuine scientific novelty directly from full manuscript text. Live 3-database retrieval waterfall (OpenAlex → Crossref → Semantic Scholar), LLM counterfactual displacement reasoning, domain-adaptive dimension weighting, and an Epistemic Groundedness Screen. Includes an automated Review Cap (0.45) and Ouroboros self-veto logic.

73.0% overall on the Liu & Zhai (2026) Axiomatic Benchmark.

SOTA 55.1% on Axiom 3 (claim coverage) vs. 6% prior embedding best — a 9.2× margin.

Special Mention, UKRI Metascience Novelty Indicators Challenge (v4.0 abstract baseline).

Active human-calibration testing with MetaROR (Leiden) and SPRU (University of Sussex).

ARIADNE — Biomedical & Rare Disease Discovery
Rung 4 · Clinical Review
A neurosymbolic evolutionary engine that breeds, scores, and falsifies rare-disease mechanistic hypotheses. Utilises a typed CausalChain graph with an 8-pressure selection genotype. Grounds claims against Monarch KG, ClinGen validity tiers, gnomAD (BA1 population frequency hard veto), HPO semantic similarity, and the BioGRID physical interactome.

Reconstructs established pleiotropic biology (FBN1, SCN5A, RYR1, LMNA).

Enforces deterministic directionality (GoF vs. LoF) via hard-coded clinical mappings.

Executed collaboration agreement with the Platt Lab at the University of Oxford to validate the V-ATPase prediction through a pre-registered iPSC neuronal assay.

AEOLUS — Net-Zero Estate Decarbonisation
Validated · 3 Pilots
A cyber-physical generative engine for public-sector decarbonisation and real-time energy flexibility. Couples LLM proposal generation with five deterministic physics/finance engines (PyPSA, HEM/SAP 10.2, CreditNature / DEFRA 4.0, Met Office UKCP18/23, Parity whole-life costing) and five VDK judges enforcing hard constraints.

Tested on three unseen public-sector estates: Leeds Teaching Hospitals NHS Trust, Lewisham Council Housing, Bournemouth University.

89.6% autonomous repair success rate across 42 runs over 5M+ tokens of telemetry.

Universal 20–25% compute savings invariant across transformer models.

Trinity WFF — Regenerative Governance
Active Development
An 11-principle constitutional genotype engine (Wholeness, Nestedness, Place, Reciprocity, Nodal Interventions, Pattern Literacy, Levels of Work, Temporal Justice, Distributed Authority, Generative Conflict, Implementation Resistance) enforcing dual Gini limits. Project Mirror injects real-time engine telemetry into the prompt context window.

Great Filter experiment: 100% initial population mortality at Generation 4 under hard constraints.

Automatic homeostatic repair triggered within 0.1 s, producing "Eve" frame recovery.

AURA-ECHO — Neurosymbolic Music Inference
Published
A neurosymbolic multi-agent engine operating over a continuous topological state space (MIDI stream as a "cloud chamber"). Generates write-locked structural primitives across an evolutionary arc (EMERGENCE → PLATEAU → DISSOLVE).

313 valid sessions / 18,819 high-resolution observations.

Independently reproduced four biological failure modes: Developmental Arrest, Metabolic Lock, Apoptosis, Brittle Rigidity.

Endorsed by Audrey Tang; 1,800+ paper downloads.

OIKOS — Passivhaus Compliance Verification
Proof of Concept
A neurosymbolic verification system for Passivhaus Classic, Plus, Premium, and EnerPHit standards across seven PHI climate zones. Six extraction sensors over architectural PDFs / PHPP models pass values to a 12-criterion deterministic math genotype and a 5-persona expert AI panel.

Evaluated on the official PHI Darmstadt benchmark: 10/10 extraction accuracy.

Zero false positives; exact agreement with published Passivhaus certification ground truth.

Architected Discovery Engine — Long-Horizon Architecture
System Blueprint
A proposal for recursive autonomous scientific discovery. Inverts DNI v6.0 into a fitness function within a closed loop: Cartographer (mapping 240M voids in literature) → Architect (constitutional mutation engine) → Gauntlet (DNI evaluation) → Breeder (MAP-Elites evolutionary search) → Simulator (digital-twin grounding).

Full technical blueprint completed (April 2026).

Designed to produce machine-authored, simulation-grounded hypotheses with pre-registered experimental protocols.
