Kat Day is a PhD chemist who was once a teacher and is now a writer and editor. By day she mostly works as a freelance editor and proofreader of scientific materials, with bits of article and book-writing thrown in. By night she… mostly does all the stuff she hasn’t managed to do during the day. She’s had articles published in Chemistry World, has written science content for DK and has produced scripts for Crash Course Organic Chemistry. Her fiction can be found at Daily Science Fiction and Cast of Wonders among others. You can follow her on Twitter at @chronicleflask , or check out her blogs, The Chronicle Flask and The Fiction Phial. She lives with her husband, two children and cat in Oxfordshire, England. She thinks black coffee is far superior to tea. The purple liquid on the stovetop is none of your concern. Kat joined the team in 2019, and became assistant editor in 2021.
