From 20–24 April 2026 my colleagues and I will be hosting the conference Farey’s legacy in frieze patterns and discrete geometry at the International Centre for Mathematical Sciences, Edinburgh. The workshop will bring together researchers in frieze patterns, continued fractions, and discrete geometry, using Farey’s legacy as a unifying narrative. Registration will open in due […]
From 12 to 16 May 2025 I attended the workshop Frieze patterns in algebra, combinatorics and geometry at the Centre International de Rencontres Mathématiques in Luminy (near Marseille). I gave three talks on Frieze patterns and Farey complexes. CIRM is located in Parc national des Calanques, a low mountainous region with rich botany and plenty […]
For several years I’ve walked at first both my daughters, and then just my youngest daughter, to school in Aspley Guise. With a new school in September those journeys will end, so we have photographed the route, recording the biota we have encountered. The journey starts from our front garden, with beech, hazel, and hawthorn […]
The Open University is recruiting a postdoctoral research associate to work on my EPSRC funded project The Farey framework for SL2-tilings. You can apply for it from the following link. Postdoctoral Research Associate – The Farey framework for SL2-tilings It starts on 1 July 2022 and lasts three years. Some background to the project can […]
I recommend this short video for the vision of Rewilding Britain.
Many thanks to those who attended today’s Royal Institution Masterclass on Navigating by numbers, which I hosted together with Margaret Stanier. The desmos activities will remain active for a couple of weeks yet, available at https://student.desmos.com/join/8k8baa. Here are the slides from the masterclass.
Thank you to those who joined Andrew and me tonight for the Navigating by numbers online workshop as part of Maths Week Scotland. Here’s the abstract for the workshop: Our exploration will take us from intriguing frieze patterns of numbers, through triangulated polygons and repeated fractions, to a beautiful infinite tessellation with remarkable properties. Along […]
I had the pleasure today of delivering a workshop in Belfast on The mathematics of dessins d’enfants as part of the Northern Ireland Science Festival 2020. This workshop explored some of the more geometric aspects of the Navigating by Numbers outreach programme. The abstract sums it up: The workshop will be an interactive exploration of […]
Today marks the launch of the Navigating by numbers outreach programme. The purpose of this programme is to communicate an attractive array of mathematical ideas centred on the Farey graph to as wide an audience as possible – from school learners to academic researchers. My PhD student Margaret Stanier and I launched the programme with an […]
