Projects

A research programme, not a portfolio.

Each project is documented the way a laboratory documents its work: the question it answers, why it matters, how it is studied, what it is finding and where it leads next.

AI and Healthcare Decision-Making

How clinical decisions are reshaped when predictive and decision-support systems enter consultation rooms, wards and referral pathways.

When machine recommendation meets clinical judgement, whose knowledge prevails — and what happens to responsibility?
Why it matters
Health systems are among the fastest adopters of AI and among the least forgiving contexts for unexamined assumptions about behaviour.
Methods
Clinical ethnographyPractitioner interviewsDecision-pathway mappingDocument and protocol analysis
Findings
Planned. Early scoping suggests overrides are rarely about disagreement with the output and often about protecting a relationship with the patient.
Impact
Practical guidance for deploying decision support without displacing the moral work of care.
Future implications
Collaboration with health services on implementation and evaluation design.

Project 04

In development

Digital Health and University Students

A study of how young adults use digital health tools, symptom checkers and AI chat interfaces as a first, informal layer of care.

What do students do with digital health information before, instead of, or alongside seeing a clinician?
Why it matters
This population is treated as digitally fluent and therefore unproblematic. Fluency and safety are not the same thing.
Methods
Focus groupsDigital diary methodsSurvey instrumentWalkthrough interviews
Findings
Planned.
Impact
Evidence for campus health services and digital health providers designing for actual help-seeking behaviour.
Future implications
Longitudinal follow-up across an academic year.
