I am a post-doctoral researcher at the Institute for Numerical and Applied Mathematics at the University of Göttingen working with Russell Luke. Prior to Göttingen, I received a PhD from the University of Newcastle (Australia) under the supervision of Jonathan Borwein where I was a member of the Centre for Computer-assisted research mathematics and its applications (CARMA). My thesis was titled "Iterative projection and reflection methods: theory and practice".
My research interests lie mostly within continuous optimisation and its applications, as well as related areas such as variational and convex analysis.
