Welcome! I am so excited by the launch of this new website! So grab a nice drink and browse through the various pages to learn more about my work and what I do. I’m quite busy with a new blog, the upcoming publication of a new book about the Enigma machine and regular tweets. Please let me know what you think too! I have a newsletter which is becoming more and more interactive so I hope you will sign up, have a read and send me a note.

My work is aimed at the nontechnical reader but everyone is welcome and I have people on my mailing list who are scientific experts and who still read my work.
