Hello! Welcome to my portfolio website. I've been a full-time freelance journalist for six years now, focusing on technology, biology and medicine. From artificial intelligence to Earth's climate, things are happening today at a pace that can seem bewildering. For me, journalism is a fantastic crash course in what's happening now and a powerful way to hold those in authority to account. My own work has been published by some of the world's top media organisations, including the BBC, New Scientist and The Economist - a few examples are listed above. I hope to keep bringing science stories to people around the globe for a long time to come.

BBC News appearance

I've appeared on BBC World TV, BBC World Service Radio, BBC Radio 4, Sky TV and other international channels. It's always a pleasure to share my stories with wider audiences and I love getting asked to contribute to programmes (hint hint!). My talks on science and technology subjects have featured at a smattering of live events in the UK and further afield. If you're looking for someone to speak at your next live science- and or technology-themed event, don't hesitate to get in touch using the form below.
