Can cutting-edge technology transform healthcare without losing its heart?

In this episode of Leadership Conversations, I sit down with Dr Mark Ratnarajah – a paediatrician turned healthcare innovator whose career spans the UK, Australia, New Zealand, and beyond. From early days in paediatric A&E to working with flying doctors in the Australian outback, Mark has always been fascinated by the interface between medicine and technology. His journey took him through Oxford, into private equity, entrepreneurship, and now into the fast-moving world of AI and health informatics – all while maintaining his clinical practice.

Together we explore how medicine, innovation, and leadership intertwine, and why the future of healthcare depends on both bold ideas and compassionate practice.

What You’ll Learn

- The Power of Early Lessons: How family resilience and childhood values shaped Mark’s purpose-driven approach to healthcare and leadership.

- Medicine Meets Business: Why stepping outside clinical practice gave him the tools to blend medical expertise with entrepreneurship and innovation.

- AI and Equity in Healthcare: The opportunities and challenges of using artificial intelligence responsibly, and why data diversity and accountability matter for fair outcomes.

Mark’s story shows us what’s possible when clinical expertise, leadership, and vision collide. It’s a reminder that healthcare’s future lies not just in technology, but in keeping kindness and humanity at its heart.
