Marianne Guenot

Doctor Marianne Guenot is a science reporter based in the UK who writes about health, AI, nuclear sciences, archeology, solar and planetary sciences, space exploration, and the commercial and political impact of science and tech. 

As part of her work, she visited the world's first final repository for nuclear waste, probed the economy of the climate crisis, untangled the complex factors playing into how the food chain pushes a health and climate crisis, tracked mysterious uranium cubes from the Manhattan project back to a Germany first prototype nuclear reactor, examined the motivations behind a tech tycoon's disastrous exploration of the deep sea, and deciphered the intricate business case behind NASA's return to the moon.

Marianne holds a master's and Ph.D. in biomedicine and a master's degree in science communication. 

She worked with Business Insider from 2021 to 2024. Before then, she edited news and opinion at The Lancet and Nature Medicine. There, she wrote editorials read by leading policymakers.
