My research focuses on turbulent/intermittent processes that occur in the exhaust region of a tokamak. In particular I focus on the behavior of mesoscale coherent bursty events known as filaments, that transport particles and heat from the confined plasma towards material surfaces. My current area of interest is the behaviour of filaments in the divertor, below the X-point. This is a poorly understood area which is proving to be much more intermittent than previously thought.
