viewEberhard MoebiusUNHSpace Science Center & Physics DepartmentDurham, NHMy research interest is centered on the acceleration of particles in and their transport through the heliosphere with the help of composition sensing ion and neutral atom sensors. Using pickup ions in the solar wind (SOHO, ACE, and STEREO) and energetic neutral atoms that originate in the interstellar gas and in the heliospheric boundary regions (IBEX), we are studying the inflow of interstellar gas into the solar system, its interaction with the solar wind, and further acceleration of its products to higher energy. With these tools we scope out the outermost shield of the Earth against cosmic rays and lay the groundwork to understanding short and long time variations of the heliosphere. In addition, interstellar and inner source pickup ions form a suprathermal particle population that serves as an effective source for the generation of energetic particles at interplanetary shocks, which contribute significantly to the energetic particle environment of the Earth.

viewScot R ElkingtonUniversity of ColoradoLaboratory for Atmospheric and Space PhysicsBoulder, COLORADOMy research has focused on techniques leading to a quantitative physical understanding of energetic particle dynamics in the inner magnetosphere and central plasma sheet during geomagnetically active periods. Central to this study is the use of the Lyon-Fedder-Mobarry MHD code to model magnetospheric configuration in response to both real and idealized solar wind conditions. Analytical magnetospheric field models are also used, where necessary, to examine relevant physical processes under simplified conditions. Finally, observational data are used both as a tool for providing realistic initial conditions within the models, and for verifying the validity of the simulations. The fundamental intent of this work is to gain a better physical understanding of the processes playing roles in storm-time radiation belt dynamics. However, all work is undertaken with an eye toward fitting these approaches within the larger framework of a global magnetospheric circulation model, and providing valid predictive tools for space weather forecasting.
viewProf. Jonathan J MakelaUniversity of IllinoisElectrical and Computer EngineeringUrbana, ILMy research interests lie in multi-technique remote sensing of the Earth's ionosphere. He works with ground- and satellite-based instrumentation to study both the quiet-time and storm-time behavior of this region at low- and mid-latitudes. To accomplish this, he develops, tests and deploys suites of sensors to sites around the world. These instruments include portable imaging systems, Global Positioning System (GPS) receivers, and Fabry-Perot interferometers. My research group is currently working on developing new techniques and algorithms to simultaneously analyze these multiple datasets to better understand the underlying electrodynamics of instability processes in the equatorial and mid-latitude ionosphere. These instabilities can cause problems for satellite navigation and communication signals that have to propagate through them. Understanding how and when they develop will lead to more robust systems.

I have dedicated a significant fraction of my research effort towards understanding kinetic processes associated with space plasma shocks, which I find particularly appealing due to their universality; shocks are ubiquitous throughout the cosmos, and the associated particle acceleration is a key contributor to the production of cosmic rays, for example.
