In my spare time, I like creating math-art and being part of the math-art community. My projects involve, more often than not, spherical imagery. Including the graphic designs on soccer balls, spherical panoramas, and novelty cartographic projections.
A lot of the work I have done with Mathematical Art has seen the light of day because of the BRIDGES conference – an international conference about the links between mathematics and art. In addition to participating, I’ve been on its Program Committee each year since 2010, and I had the honour of being the chair of the program committee in 2017, and again in 2021.
