DPhil Student

I am a DPhil Condensed Matter Physics Student cross-appointed between the University of Oxford at Clarendon Laboratory and ISIS at the Rutherford Appleton Laboratory (RAL). I work with both Prof. Thorsten Hesjedal and Dr. Nina-Juliane Steinke. I received my MSci Degree in Physics from Royal Holloway University of London (RHUL) where I conducted research on Nanoelectromechanical Systems (NEMS) with SQUID based motion transduction for my masters project. I have also conducted research in Nanomagnetism during summer internships spent at the National Physical Laboratory (NPL) where I performed magnetoresistance measurements on permalloy nanomagnetic devices and also created a vector magnet system for use with nanosamples.

My research involves Investigating Magnetic Order in Topological Insulators. Using molecular beam epitaxy (MBE) I synthesize ferromagnetically doped topological insulator films and sophisticated ferromagnetic proximity heterostructures. This growth is supported by advanced characterisation facilities at the Rutherford Appleton Laboratory such as neutron and X-ray based techniques in order to investigate the fundamental mechanism of ferromagnetic doping and proximity coupling of topological insulators which will lead to a wealth of spin-based phenomena by combining ferromagnetic films and topological insulators in hybrid structures.
