Our technology-driven society is dependent upon satellite technology for communication, navigation, and national security, as well as upon a reliable power grid for everyday needs such as money transactions, job functions, and food storage. These infrastructure systems are vulnerable to geomagnetic activity, when charged particles in the space surrounding Earth are energized and transported due to energy input from the Sun. My research centers on studying these charged particles during enhanced geomagnetically active events to improve our understanding of and eventually be able to forecast the characteristics of space during them. Such improved space weather forecasts would provide a reliable warning system to protect satellite and power grid infrastructure.

My research includes three areas: magnetospheric physics, instrument development, and laboratory plasma physics. In magnetospheric physics, I analyze satellite-based data to understand the dynamics of the magnetosphere during geomagnetic storms. These data are often incorporated with computer models to improve understanding of the underlying physics. I am working to develop the next generation of plasma spectrometers to measure charged particles in space, particularly on small platforms such as CubeSats. The spectrometer is also being developed as a diagnostic for fusion energy producing plasma research. I am also involved in laboratory based plasma physics research, particularly with laser-based diagnostics. These studies help us to understand space-relevant phenomena.
