Background and activities
I am currently working with Prof Dennis Meier to investigating next-generation 2D materials for future nanotechnology. My research interests are in any ferroic system and their domain walls, specifically how to manipulate  and control the domain walls.
Postdoc with Prof Michael Carpenter, Department of Earth Science, University of Cambridge. Measuring elastic and anelastic to investigate the role of elastic strain and microstructure dynamics in controlling the structural evolution, as a function of temperature and magnetic field. We investigated skyrmion system Cu2OSeO3 , double perovskite solar cells  , and high temperature superconductors, in submission.
PhD with Prof Marty Gregg and Dr Alina Schilling, Physics department, Queen’s University Belfast.
PFM and FIB lead investigation the first single phase multiferroic material with room temperature magnetoelectric coupling   . With a focus on the nature of the magnetoelectric coupling  .
Masters Project with Prof. J. F. Scott, Physics department, University of Cambridge .
