BIO
I use contemporary asymptotic methods to find solutions to continuous and discrete problems arising within applied mathematics, and explore behaviour that is invisible to classical asymptotic methods. I spend a lot of time looking at a special class of behaviour known as the Stokes Phenomenon, that only appears at exponentially small orders in an asymptotic expression. Understanding this behaviour can be an important way to describe effects that normally lie beyond the reach of common asymptotic methods.
I studied a BEng (Hons)/BAppSci (Hons) at the Queensland University of Technology in Brisbane, writing an Honours and Masters project with Prof. Scott McCue. I moved to the University of Oxford in 2009 to study for my DPhil., under the supervision of Prof. Jon Chapman, studying exponential asymptotics in unsteady and three-dimensional flows. I was awarded my doctorate in 2013.
I moved back to Australia, and worked at The University of Sydney as a postdoc with Prof. Nalini Joshi on the asymptotics of discrete integrable systems. In 2016, I was appointed as a Lecturer in Applied Mathematics at Macquarie University where I worked until 2023, after which I returned to The University of Sydney in my current role as a Senior Lecturer in Mathematics.
