I am an independent theoretical physics researcher developing D1 Field Theory, a proposed fundamental field framework investigating the underlying structure from which spacetime, gravitation, cosmology and particle-physics phenomena may emerge.
My research combines theoretical modelling, mathematical analysis, numerical simulation and computational physics.
D1 Field Theory proposes that a fundamental D1 field underlies the physical structure of the universe.
The research programme investigates whether phenomena normally described by separate physical theories can emerge from the dynamics and structure of a common underlying field.
Current areas of investigation include:
- Spacetime emergence
- Gravitation and General Relativity
- Black-hole structure and interiors
- Cosmology and cosmic acceleration
- Baryogenesis and matter–antimatter asymmetry
- Particle physics
- Composite Higgs models
- Higher-dimensional structure
- Quantum foundations
- Numerical and computational physics
My current theoretical programme is focused particularly on the relationship between D1 Field Theory and General Relativity.
This includes investigating whether Einstein gravitational dynamics can be derived from the underlying D1 field, developing a working D1 description of black-hole interiors, and investigating the microscopic origin of Newton's gravitational constant (G).
I am also developing computational models to investigate the behaviour of D1 systems and their possible emergent physical properties.

This research develops a D1 Composite Higgs framework involving discrete (Z_4) crystalline vacua and investigates its numerical structure and phenomenological implications for LHC physics.
My wider D1 research programme and research outputs are archived through Zenodo and Figshare.

This repository contains code, numerical experiments and supporting material developed during the D1 research programme.
The computational work is used to investigate theoretical predictions, test mathematical constructions and explore numerical behaviour within D1 models.
Where appropriate, code and numerical results are provided alongside the relevant research work to support reproducibility and further investigation.
I am commencing formal university-level study in physics at The Open University in September 2026.
My long-term objective is to develop D1 Field Theory into a mathematically rigorous fundamental physical framework and to investigate its predictions against established theoretical, observational and experimental results.
D1 Field Theory is a developing research programme. I distinguish between established results in physics, mathematical results derived within the D1 framework, numerical investigations, and speculative or proposed physical interpretations.
The objective is to develop the theory mathematically and subject its predictions to increasingly rigorous theoretical, numerical and observational tests.
