Dr. Michael Wiltberger is a Scientist III in the High Altitude Observatory of the National Center for Atmospheric Research. His main research interest is modeling and analysis of magnetospheric processes using global scale magnetohydrodynamic simulations. Specific areas of interest include coupling between the magnetosphere and ionosphere, structure and dynamics of ultra-low frequency waves and their impacts of radiation belt particles, and coupling between the magnetotail and the inner magnetosphere during storms and substorms.
