Profile

I completed my PhD at Sidney Sussex College, the University of Cambridge, in 2007, under the supervision of the late Professor Tony Bland. I subsequently worked in post-doctoral positions, both in Cambridge and at the University of Sheffield, before being awarded an EPSRC Career Acceleration Fellowship in 2012, which I used to start my own group. I became a lecturer in 2017, a senior lecturer in 2020, and Professor of Materials Physics in 2024. My groups work is/has been supported by grants from a range of funders including EPSRC, Leverhulme trust, the European Commission, the Royal Society, and the Sir Henry Royce Institute.

Research interests

My research explores the use of nano-scale magnetism and spintronics (spin-electronics) to create new, energy-efficient computing devices, as well understand fundamental physics. The majority of my group's research is currently focused on developing new neuromorphic (brain-like) computing devices that will allow us to use artificial intelligence at a fraction of its current energy cost. More broadly, my group has expertise in the growth of high-quality magnetic thin films and multilayers, the lithographic patterning of these into nanodevices, experimental characterisation via a wide range of techniques and simulation of device behaviour.

Key research interests:

  • Magnetism
  • Spintronics
  • Magnonics
  • Neuromorphic Computing
  • Unconventional Computing
  • Machine Learning
  • Micromagnetic Simulation.
