Gareth Mitchell lectures in science communication at Imperial College London. For many years he presented the weekly technology programme Digital Planet on the BBC World Service. He also presents occasionally on BBC Radio 4’s Inside Science. We explore parallels between Gareth’s work as a presenter and podcaster and my own experience as a clinician.
