Dr. Steven Tomczyk is a Senior Scientist Section Head in the High Altitude Observatory of the National Center for Atmospheric Research in Boulder, Colorado. His is an expert in the development of instrumentation for the measurement of magnetic fields in the solar corona, chromosphere and photosphere, with the goal of understanding the Sun's influence on the Earth.Dr. Jie Zhang is an Associate Professor at George Mason University. His research interests have two folds. The first one focuses on fully understanding the physical mechanisms of solar flares and coronal mass ejections (CMEs), the two most energetic phenomena occurring on the Sun that also affect the environment throughout the entire solar system, including the space near the Earth, Moon and Mars. The second one focuses on the practical purpose of creating robust models to characterize the initiation and propagation of these eruptions across the integrated Sun-Earth system, with the aim of providing an accurate prediction of space weather.Dr. Timothy Bastian is a scientist at the National Radio Astronomy Observatory.
