I am a DPhil student at the University of Oxford working with Prof Alex Schekochihin (Oxford) and Dr Anthony Field (CCFE). I am interested in all manner of plasma turbulence, but my research focuses on the generation and stability of zonal flows in tokamak plasmas. My DPhil work is centred around a fluid model for ion-scale turbulence in tokamak plasmas that is derived from the more general gyrokinetic equations
