Why nuclear power will (and won't) stop climate change

I was recently interviewed by science communicator Simon Clark for his latest science video “Why nuclear power will (and won’t) stop climate change” (below). The final result is a brilliant deep dive into nuclear power, and the nuclear versus renewables decarbonisation debate.

Bringing papers alive with video abstracts

As an early-career researcher, building up a decent publication record can feel like a real battle. By the time you’ve finished your work and written it up according to your chosen journal’s particular specifications, the last thing you might feel like doing is spending more time getting it publication-ready.
