I am a science writer, biographer, author and broadcaster. I live in Oxford, UK, and write about science and scientists past and present.

I write mainly about the life sciences, then and now, and also have a particular interest in women in science. I’m fascinated by the lives of scientists and their interactions with the society in which they live.

New! My biography of Dorothy Crowfoot Hodgkin was reissued in October 2019 in a slightly revised and updated edition, with a new title. There is also an audiobook for the first time, which I narrated myself.
