Jan J. SojkaJan J. Sojka is Department Head of the Department of Physics at Utah State University. His research explores how our upper atmosphere and its ionosphere are coupled with the magnetosphere and driven by the Sun and solar wind in an effort to unravel ipacts on our technologies, focusing particularly on the modeling of the ionosphere and its couplings and drivers, to enable assessments of how well our theories conform to reality. For over four decades, Professor Sojka has been involved with sounding rockets, and magnetospheric and ionospheric satellite missions, as well as numerous ground-based facilities. He is currently Co-Investigator on the NASA SDOs EVE instrument observing the X-EUV solar irradiance. Read More Read Less
