Welcome! I am a Sherman Fairchild Postdoctoral Fellow at Caltech, studying a variety of topics in plasma physics, fluid dynamics, numerical methods, geophysics, and astrophysics. Much of my work focuses on the theory of turbulence and generation of magnetic fields (the dynamo). Such processes are fundamental to a wide variety of geophysics and astrophysics, including the Earth’s magnetic field, the solar wind, stars, galaxy clusters, accretion disks, and the question of why the universe should be magnetized at all. I also work on the dynamical interaction of dust and gas and have previously studied Hamiltonian mechanics, symplectic numerical algorithms, guiding center and gyrokinetic theory.
