Brief Bio


My main research interests are in developing the capabilities of radiation-magnetohydrodynamics simulations to investigate various open problems in the atmosphere, wind, and circumstellar environment of our sun and those of other stars. Currently my work is focused on the heating of the solar corona around active regions; physical processes responsible for individual flares and coronal mass ejections; and the way that coronal mass ejections evolve as they propagate outward in the solar wind into interplanetary space. I also have an ongoing research interest in the interplay of matter and radiation in the launching and structuring of the winds of massive, luminous stars across their evolutionary sequence.
