Join Professor Michele Barbour for an energising and deeply insightful conversation with Dr Luke Cox, CEO of Impulsonics, a University of Bristol spin‑out transforming how cell handling and automation are done in biotechnology. What begins as an exploration of Luke’s journey from engineering undergraduate to PhD researcher becomes an exhilarating story of invention, grit, and entrepreneurial drive. From early work in acoustic levitation to co‑developing a novel “impulse control” technology, Luke unpacks how a speculative research project evolved into a breakthrough method for moving millions of cells simultaneously — enabling automation where traditional tools have long failed. Discover how Luke navigated the risks, setbacks, and thrill of taking on the role of CEO while spinning out a deep‑tech company; how customer discovery reshaped their market focus; and why Impulsonics’ modular, ultrasound‑based approach could unlock scalable personalised medicine, reduced lab waste, and new possibilities in drug discovery. This is a candid discussion about ambition, risk engineering, accidental luck, and finding the “beachhead market” that biologists have needed for decades — all told with Luke’s characteristic insight, humility, and humour. In this episode From engineering undergrad to PhD researcher: discovering acoustic levitation The origins of “impulse control” and its biocompatible applications Why automation in biotechnology breaks down — and how Impulsonics bridges the gap Building prototypes, identifying markets and finding early‑stage grant funding Becoming CEO: translating between tech, biology, and business How automation could enable precision functional medicine The role of AI: hype, data quality, and industry realities Storytelling, improv theatre, and becoming unafraid to ask “stupid questions” Advice for early‑career researchers and aspiring entrepreneurs 🌐 About the Enterprise Sessions The Enterprise Sessions bring together founders and researchers to share candid insights on spin-outs, start-ups, raising capital, and translating research into real-world impact.
