About

Ut ab ordine chaos, sic ab absurditate veritas.
As from order, chaos; so from absurdity, truth.

PhD studying evals under randomness with GNNs.

Particularly interested in evaluation frameworks, turning research into useful production ML systems, and the intersection of randomness and model performance.

Timeline

July 2025 - Present Current

AI Engineer

StackOne

Building AI features and training tool-calling models. First month spent building an AI agent that translates provider errors into clear resolution steps.

June 2024 - June 2025

ML Engineer

OKKO Health

Built predictive models for early disease detection using remote patient monitoring data for AMD macular degeneration patients. I'm proud to have developed an AI anomaly detection system to support the mission of preventing avoidable blindness.

2020 - 2024

PhD in Artificial Intelligence

University of Bristol

Researched best practices for evaluations and evaluating under randomness. Thesis: 'Unsupervised Graph Neural Networks' - focused on evaluation methodologies and model comparison. Defined metrics for quantifying model performance under uncertainty, with applications in graph neural networks and beyond.

2016 - 2020

MEng Engineering Mathematics (1st with Honours)

University of Bristol

Applied mathematics to real-world engineering challenges through an interdisciplinary lens. Core focus on mathematical modelling, data science, and machine learning fundamentals. Master's dissertation explored biologically-inspired RNN Hebbian learning rules for decision-making processes. The program's emphasis was on on bridging pure mathematics with practical engineering applications.
