Jonathan Hickman
I am lecturer in the analysis group at the University of Edinburgh. Previously, I held postdoctoral positions in the University of Chicago, MSRI and the University of St Andrews. A CV can be found here.
Research
My interests lie in Euclidean harmonic analysis, in particular questions pertaining to operators whose definition depends on some submanifold
of \(\mathbb{R}^n\) such as Fourier restriction/extension operators and generalised Radon transforms. I am also interested in discrete analogues
of these objects.
