Andy Extance

Before becoming a full-time science writer, Andy Extance worked for six and a half years in early-stage drug discovery research, followed by brief stint in silicone adhesive and rubber manufacturing.

However, when he had his first feature – on a cause of common heart-related problems in new drug candidates – published in Chemistry World in 2004, the course of his career shifted. After working as news editor for Compound Semiconductor magazine, he went freelance in 2009. Today Andy’s science writing explores everything related to chemistry, from Earth’s environment to space, from food to fusion, and from solar cells to how we smell.
