James Nicholls

Senior User Researcher — UCD × AI

Discovery to beta in government’s most complex, secure services — and research into how organisations adopt AI.

Available from 15 September 2026 Contract user research Outside IR35 Remote / hybrid London–Kent

I’m a user researcher who works in government’s more complex corners — defence, justice, trade, weather — where services are high-stakes, regulated, and often behind a security fence. Fifteen-plus years of GDS-aligned research, from first discovery interview to live assessment, turned into the maps, models and evidence that product teams actually use.

Where I’ve worked

Ten organisations, from defence data to the national weather service.

MOD Data Services — research across security tiers

Senior User Researcher · 2025–2026 · OFFICIAL-SENSITIVE and SECRET environments

Ten months setting research strategy for a defence data portfolio.

The work

Ten months leading research for the MOD’s data services portfolio, including its data and analytics platform. I ran multi-method programmes — depth interviews, a diary study, moderated sessions — with analysts, data scientists and RAF users, and set the portfolio’s research strategy.

What it changed

The work surfaced how tooling and workflows break across classification tiers, published as interactive evidence packs that informed platform and investment decisions. I also built the portfolio’s user-needs repository and brought user evidence into the department’s AI adoption work.

  • Depth interviews
  • Diary study
  • Moderated sessions
  • Research strategy
  • User-needs repository

How I work

Evidence first

GDS-aligned, multi-method — interviews, diary studies, ethnography, usability — synthesised into artefacts teams use, not decks that get filed.

At home in hard places

Secure, regulated, mission-critical settings; comfortable earning access and trust where research is hardest to do.

UCD × AI

I bring AI into the research workflow where it earns its place — and research how organisations adopt it.
