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 Principal Investigator on an NSF project to improve capabilities to predict electron precipitation in geospace weather and on a NASA project to explore the hypothesis that ionospheric outflows are integral in the development of a planetary-scale oscillation known as the magnetospheric sawtooth mode. 

I  teach courses at Dartmouth in engineering design, applied mathematics, electromagnetic fields and waves, magnetohydrodynamics and plasma physics, space systems engineering, 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, and my research community as editor-in-chief of the Journal of Atmospheric and Solar-Terrestrial Physics, associate editor of Journal of Geophysical Research and Geophysical Research Letters, convener of many scientific sessions, workshops and symposia, and panelist and contributing author for two National Academy of Science Decadal Surveys of Solar and Space Physics.
