Andrew is a harmonic analyst who specialises in developing functional calculus methods to investigate solutions to partial differential equations in rough geometric contexts. His current research is partially supported by the Royal Society International Exchange grant Eliminating symmetry and permitting singularity in periodic homogenization.

  • PhD in Mathematics, Australian National University, 2011
  • BSc (Hons) in Mathematics, University of Queensland, 2004


Andrew obtained a Doctor of Philosophy in Mathematics from the Australian National University in 2011. He subsequently held postdoctoral positions at the University of Missouri and the University of Oxford before joining the University of Birmingham as a Lecturer in Mathematical Analysis in 2015.


Semester 2

LC Real Analysis

Postgraduate supervision

Andrew is interested in supervising postgraduate research students in harmonic analysis, operator theory and partial differential equations. Some example projects include those given below.


Research Themes

Andrew’s research concerns the development of modern techniques in harmonic analysis, functional calculus and geometric measure theory for application to partial differential equations on Riemannian manifolds and rough domains. This includes elliptic systems with rough coefficients, local T(b) techniques, first-order methods, quadratic estimates, holomorphic functional calculus, singular integral theory, layer potentials, Hardy spaces, boundary value problems and uniform rectifiability.
