Whilst at Usborne Alice has worked on books on all kinds of science topics, from space to energy to the periodic table.

Micaela Tapsell

Biography

Originally from Zimbabwe, Micaela has always enjoyed learning about different cultures and exploring the great outdoors. When she’s not rafting the rapids of the Zambezi river or camping among the African wildlife, she is writing books on all sorts of delightful subjects, from science’s greatest unknowns to the wildflowers of the world.

Tom Mumbray

Biography

Tom studied History at university before joining Usborne in 2018. Since then he’s worked on books about Planet Earth, technology, maths and inventions (and learned lots of amazing facts about everything from paleoburrows to fireworks along the way).
