Jan Sojka is a Professor and Department Head in the Department of Physics at Utah State University's College of Arts & Sciences. He serves as president of the Space Science and Aeronomy Section of the American Geophysical Union and is a member of the Center for Atmospheric and Space Sciences (CASS). His leadership extends to national scientific initiatives, having chaired the National Science Foundation CEDAR Science Steering Committee from 2005-2007.
- BS in Physics from Edinburgh University, 1976
- PhD in Auroral Suprathermal Electrons from University College London, University of London, 1976
Professor Sojka's research focuses on ionospheric and magnetospheric physics, with particular expertise in space weather phenomena, heliophysics, and ionosphere-thermosphere coupling. His work combines theoretical modeling with observational data analysis to understand complex space plasma processes. He has made significant contributions to understanding geomagnetic storms, substorms, and the dynamics of the Earth's upper atmosphere. His research group employs wavelet analysis techniques to study magnetospheric and ionospheric currents, contributing to improved space weather forecasting capabilities.
An analysis of his 15 most recent publications reveals a strong emphasis on space weather applications, particularly in ionospheric modeling and forecasting. His work spans multiple disciplines including space physics, atmospheric science, and statistical analysis. Key research themes include the development of data assimilation techniques for ionospheric specification, understanding the impacts of solar variability on the Earth's upper atmosphere, and characterizing ionospheric irregularities that affect radio communications and navigation systems.
- Utah Professor of the Year, 2002 (Carnegie Foundation for the Advancement of Teaching)
- D. Wynne Thorne Research Award, 1999 (Utah State University)
Professor Sojka has mentored several graduate students including David Smith (2014), Chad Fish (2010), and Jennifer Meehan (2015-2017). His research has been supported by multiple NSF grants, including the WAMI (Wavelet Analysis of Magnetosphere and Ionosphere) project funded by NSF award DMS-0413653. He has served on NSF and NASA review panels and has contributed to major scientific initiatives through his leadership roles in professional organizations.
He leads the WAMI research project, a collaborative effort between space physicists and statisticians focused on developing advanced techniques for analyzing magnetospheric and ionospheric currents. The WAMI team has developed new statistical methods based on wavelet and functional data analysis to better understand space weather phenomena and improve storm activity indices.
