Hello! I am Chris Baraniuk, a freelance science and technology journalist based in Belfast, Northern Ireland.
My work has been published by some of the world's top media organisations, including the BBC, New Scientist, Wired, National Geographic, The Guardian, Science and The Economist.
From climate change to the Covid-19 pandemic, events can unfold today at a pace that
seems bewildering. In my view, good journalism is able to help people both understand and navigate a complex world. When I begin working on a new story, I set out to investigate and learn — then pass those learnings on.
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 new audiences and I love being 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 gathering, don't hesitate to get in touch using the form below.
Feel free to send me an email. You can use this contact form, or shoot something over to chrisbaraniuk [at] gmail [dot] com. (Which is where the form will send your email anyway!) You might also like to follow me on BlueSky.
