My research within the broader field of geospace science focuses on system-level studies of the solar wind-magnetosphere-ionosphere interaction, its plasma electrodynamics, magnetohydrodynamics, and collisionless transport processes, with applications to space weather prediction. With my students and research collaborators, I am currently investigating and developing simulation models for ionospheric outflows into the magnetosphere; electron precipitation into the high-latitude ionosphere and thermosphere; plasma kinetics that enable superfluent ion outflows and electron precipitation; and the effects of all of these processes on global geospace dynamics. I serve as Principal Investigator for Dartmouth’s Heliophysics Theory Project sponsored by NASA, and I am a co-investigator with the Center for Integrated Space Weather Modeling, a multi-institutional Science and Technology Center sponsored by NSF. I am also team leader, with six other principal investigators, for one of NASA’s Living With a Star, Targeted Research and Technology projects focusing on geospace dynamics during storms. I teach courses at Dartmouth in engineering design, applied mathematics, electromagnetic fields and waves, magnetohydrodynamics and plasma physics, and on issues in technology and society. In past years I have served the School of Engineering as Director of its MS/PhD Program, Senior Associate Dean, and Interim Dean.
