Research

My current work has two aspects. One involves the use of double dots to probe single electron physics in both silicon and superconducting aluminium, and perhaps to implement the building blocks of future quantum technologies. The other involves the coupling of high-Q magnetostatic modes to optical cavities, part of the rapidly expanding field of magnonics.

I'm also interested in other aspects of low dimensional device physics, particularly the properties and applications of nanowires and arrays of nanocolumns.
