I’m Dr Michael Welsh (or Dr yomcat), from Wellington, New Zealand. I was married on the 23rd of February 2008 to Melissa (this is so I can remember our wedding anniversary). My mathematical adventures, including my theses (hilarious word) are on the Internet for everyone to not understand.

I’m interested in mathematics, mainly of the discrete kind, with combinatorics a special interest.

I am also a keen amateur photographer, and so I feature a fair bit of my photography on this blog.
