Research interests
Much of the visible matter in the Universe exists as magnetised plasma in a state of chaotic, turbulent motion. I am interested in the complex roles that magnetic fields play in generating and mediating this turbulence. A particular interest is how microphysical plasma-physics processes like “magnetic reconnection”, whereby the topology of magnetic-field lines changes, can conspire to control dynamics on the largest astrophysical scales.
Teaching Interests
In the past I have taught undergraduate physics courses on mathematical methods, thermal and statistical physics, fluid dynamics and plasma turbulence.
