This is really only meant as a collection of links I use frequently, so there is no need to send me suggestions for missing links (believe it or not, this happens!). In addition, you may want to browse around the site if you are after my contact details for professional purposes or need a copy of one of my articles (my history of science papers only). Feel free to drop me a line if you have any queries! Or click here for my academic skills training and public speaking site.

Please see our group's PhD positions available page for any opportunities to pursue a PhD in astrophysics; if you're interested in a PhD in the history of astronomy, and specifically the history of maritime navigation and the "longitude problem", please get in touch as I have a few projects in mind!
