Ben Fairbairn

Senior Lecturer in Mathematics

MMath MA (Cantab) PhD (Birmingham) FHEA

Hi! Welcome to my website. Thanks for stopping by.


In 2018/19 my main BSc teaching responsibilities is Real & Complex Variable. On the MSc I am teaching Group Theory. All materials can be found on moodle.


My research is primarily concerned with groups and related matters in combinatorics and occasionally even geometry. A more comprehensive account of who I am, where I've been and what I do can be found here (and in particular my publications and preprints, many of which are also on the arXiv can be found here).

My Erdős number is 2 (Erdős-Cameron-Fairbairn). Since Erdős finally stopped publishing about a decade after he died (well, almost), this is about as low as it can possibly get!

How to find me virtually

Typing b.fairbairn and then typing one of those fancy "at signs" before proceeding to type in an appropriate place (I recommend some form of software that is designed to send emails) should get my attention.
