Ghana Engineer Builds AI Chatbot to Fight Hypertension

When Audrey Agbeve put on glasses for the first time at 13, the world snapped into focus. She didn't know everyone else could already see the details on chalkboards, the sharpness of distant faces, the depth of colors she'd been missing.

That moment of clarity changed everything. The simple power of science to transform lives stayed with her, guiding her toward biomedical engineering and eventually to artificial intelligence.

At Kwame Nkrumah University of Science and Technology in Ghana, Audrey faced a practical challenge for her final year project. She wanted to help people manage hypertension, but complicated health apps often fail in communities with limited resources. So she asked a different question: what if the technology met people where they already were?

The answer was WhatsApp. Nearly everyone in Ghana already uses it daily, trusts it, and knows how it works. Audrey built an AI-powered chatbot that delivers hypertension education through the messaging app people already have in their pockets.

The project worked because it was simple. No new downloads, no training sessions, no fancy interfaces that might confuse users. Just helpful health information arriving through a familiar, trusted platform.

Her work caught the attention of researchers at the Kumasi Centre for Collaborative Research in Tropical Medicine. Now Audrey works in their AI and Digital Health unit, surrounded by clinicians, data scientists, and fellow researchers who share her vision.

Working alongside doctors and mentoring students has taught her something crucial. Technology doesn't succeed because it's clever or elegant. It succeeds when it fits into real workflows, functions within actual infrastructure constraints, and makes sense to the people using it every day.

Why This Inspires

Audrey's approach challenges how we think about health innovation. She's not chasing flashy prototypes or pilot projects that fade after funding runs out. She's building tools designed to last, to scale, and to reach communities often left behind by healthcare advances.

Her focus on sociotechnical approaches recognizes a truth many tech developers miss: health systems are as much about people and society as they are about code and algorithms. The best solution is useless if people can't or won't use it.

As the world marks the International Day of Women and Girls in Science, Audrey's journey from blurred vision to health innovator reminds us that breakthrough solutions often start with seeing a problem clearly and asking better questions.

She's helping others see new possibilities in healthcare, one WhatsApp message at a time.
