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.

Since 2018 I have made something of a speciality of writing scientific obituaries.

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.
