Applied mathematics · AI safety · Cardiff, UK

Ioan Barber.
Mathematics for a safer AI future.

A Cardiff mathematician working where AI safety, machine learning, and growth marketing meet. I help people and organisations build things that are careful, effective, and ready for what's next.

About

I'm a third-year MMath student at Cardiff University. I believe helping society safely navigate the arrival of transformative AI is one of the defining challenges of our time, and that field-building is one of the highest-leverage ways to help.

I'm incoming Vice President of the Cardiff University AI Safety Society and founding AI Safety Hub Wales, connecting Welsh businesses with vetted AI safety professionals. Under that sits a technical core in mathematical modelling, simulation, and machine learning, and a performance-marketing background from co-founding a growth agency.

I lecture and tutor mathematics entirely in Welsh. Whatever the project, I aim for work that's rigorous, honest, and genuinely useful.

What I do

Three kinds of work. Each one starts with the same short form at the bottom of the page — pick the topic and tell me what you need.

Growth & marketing

Meta-certified paid social and search, landing pages, and lead funnels — plus the positioning and content to actually scale a brand, not just run ads. This is the growth engine I built co-founding an agency.

Founders & ideas

Building something? I work with early founders — idea through to first revenue — on product and go-to-market, warm introductions, and small cheques where it fits. I take a particular interest in AI, applied maths, and simulation. Early and rough is fine, and what you send stays between us.

Academic & tutoring

One-to-one maths tutoring from A-level to Master's, in English or Welsh, and mentoring for people heading into research or an AI-safety career. AI-safety advisory too, through AI Safety Hub Wales.
