I am a postdoctoral researcher at the Inria Saclay Centre in Palaiseau, France, where I am working with Gabriel Scherer and Noam Zeilberger in the PARTOUT team.
Before that, I was a PhD student at the Centre of Australian Category Theory (CoACT) and Macquarie University in Sydney, Australia.
I am broadly interested in category theory and its applications, and so far my research has focused on lenses, (op)fibrations, cofunctors, and double categories.
