I am a member of the Centre of Australian Category Theory at Macquarie University.
My research interests are in category theory, especially higher and enriched category theory, and categorical aspects of homotopy theory.
During May 2017--June 2019, I was a Postdoctoral Research Fellow in the Department of Mathematics and Statistics at Macquarie University.
In January--May 2020, I will be a Postdoctoral Fellow in the Higher Categories and Categorification program at MSRI.
