Bayesian Teaching for Personality Inference in LLMs

Six open-weight LLMs were taught to perform Bayesian belief updating over Big Five personality traits — extending the Qiu et al. (2026) framework from task-level preferences to stable trait inference.

Fine-tuned models matched the Bayesian teacher within 0.5pp on a 50-item questionnaire, and the inferred personality model transferred to an unseen flight-recommendation task with no task-specific training data.

Experience

Bloomberg

Data Engineering Intern

2025

Built automated Python pipelines integrating multiple internal sources, reducing processing time by 98%. Anomaly-detection logic surfaced data-quality issues feeding London-wide trading and risk reporting.

Full Spectrum

Operations Manager

2024–25

HealthTech startup supporting parents of autistic children. Drove product development and user research, ran user interviews, iterated on prototypes, and built investor pitch materials.

Solenya

AI Researcher

2024

Investigated zero-shot recommendation systems, boosting new-user recommendation accuracy by 15%. Synthesised findings into actionable technical reports.

Addionics

Data Analyst

2023

Automated data collection, cleaning, and visualisation of battery test results in Python, streamlining reporting for R&D decision-making.

Edinburgh AI Society

Funding Lead

2023 – present

Scaled membership from 30 to 400+. Helped secure Anthropic as headline sponsor and personally closed Nebius, Wordsmith AI, and Malted AI.

Selected work

Research, systems, and product-shaped engineering.

The common thread is practical intelligence: models that adapt, data systems that make messy signals usable, and interfaces that help people understand what is happening underneath.
