I am a post doc in the [Centre of Australian Category Theory] at Macquarie University.
I work on operad-like structures, their higher analogues, and their applications, particularly in topology.

I’m particularly interested in modular operads and other structures described by graphs admitting cycles. Watch this space for more notes on loops and sphere contractions.

I’m also keen on weak (modular) operads, and always keen to think about generalised associahedra and their symmetries.


  • Operad Theory (in particular modular operads)
  • Higher (modular) operads
  • Applications in mathematics and beyond


I’m in the process of building a site with more detailed and accessible information on my research. Until then, feel free to take a look at the following:

  • Here is the most up-to-date version of my paper on a distributive law for modular operads (CSMs). Please note, this is an unfinished draft and has not yet been proofread.

  • My preprint together with L. Bonatto, S. Chettih, A. Linton, M. Robertson and N. Wahl on a weak operad of normalised cacti is here.

  • On 11 August 2020, I’ll be speaking at Operads Pop-up. Talk slides will appear here.

You can find my cv here.

Please feel free to get in touch if you want to talk about loops, sphere contractions, or anything else related to the topics mentioned above. I’m also keen to hear from others interested in questions of (neuro)diversity and retention in maths.

More soon!
