Welcome! I am a Sherman Fairchild Postdoctoral Fellow at Caltech, studying a variety of topics in plasma physics, fluid dynamics, and numerical methods. Much of my work focuses on understanding basic processes that govern the dynamics of gas and plasma in astrophysics: instabilities, the theory of turbulence, and the generation of magnetic fields (dynamo). Such processes are fundamental to a wide variety of astrophysics and geophysics, including the Earth’s magnetic field, the solar wind, stars, galaxy clusters, accretion disks, the interstellar medium, and the question of why the universe should be magnetized at all. I have also previously studied Hamiltonian mechanics, symplectic numerical algorithms, guiding center and gyrokinetic theory. Please visit my research page or publications for more information.
