Dr. Lie Zhu received his B.S. degree in physics from University of Science and Technology of China in 1982, M.S. degree in space physics from University of Science and Technology of China in 1985, and Ph.D. degree in space physics from University of Alaska Fairbanks in 1990. In September 1990, he joined the Center for Atmospheric and Space Sciences (CASS) at Utah State University as a post doctorate. Currently, he is research associate professor.

During his research career, Dr. Zhu has conducted theoretical studies, numerical modelings, and simulations in a broad area of space plasma physics, with the focus on magnetosphere-ionosphere coupling, substorm phenomena, polar cap arcs, Alfven wave propogation, field-aligned currents and potential drops, MHD instabilities, high-latitude phenomena during northward IMF, flux transfer events, and ground magnetic perturbation. Dr. Zhu also has substantial experience in data analysis and model-observation comparison studies.

Dr. Zhu has authored or co-authored more than 40 scientific papers and has given more than 40 presentations at both national and international meetings. He was an associated editor of the Radio Sciences for the HLPS special section from 1995 to 1998.
