I am a PhD student in the School of Mathematics and Statistics at the University of Sheffield, under the supervision of Nick Gurski. My area of interest is category theory, particularly concerning coherence and operads/multicategories. I have recently been thinking about coherence for 3-categorical structures by considering computads for 3-globular operads.


(With Nick Gurski) Operads with general groups of equivariance, and some 2-categorical aspects of operads in Cat
