Main Focus

Solar activity is driven by the evolution and dynamics of the solar magnetic field. The photosphere offers the last visage of the magnetic signature before it is lost below the surface. I am interested in the coupling of the photospheric magnetic field to the subsurface layers, which will  provide more boundary conditions for solar dynamo and solar flux emergence models. An extension of this, is to use asteroseismology to infer not only the structure and rotation, but also the magnetic properties of stars. 
To correctly infer the interior stellar properties it is necessary to understand the physics of the wave interactions with the magnetic field, and much of my work has focused on this research.
