My primary research interests lie in understanding the ultrafast spin dynamics at the nano-scale and then in exploring ways to exploit spins and spin waves (magnons) in practical applications, e.g. within magnonics and magnetic data storage technologies.

Further details of my research projects can be found at the magnetic materials research pages.
