Geophysics & Planetary Physics
University of California, Los Angeles (UCLA)
Post Doctorate Researcher in the UCLA Institute of Geophysics and Planetary Physics, Space Weather Group.
For his Ph.D. dissertation, Dr. Zhang studied the transport of energetic particles in the interplanetary magnetic field. He used theoretical modeling to understand the propagation of solar energetic particles in the inner heliosphere. His most recent experience has been in the observation and analysis of high resolution solar magnetiograms, with emphasis on the sun's polar magnetic field.
Dr. Zhang came to UCLA in January 1997 to work with Dr. R.L. McPherron on magnetic storm research. His present interests concentrate on energetic electrons in the magnetosphere and the importance of the state of the magnetosphere on ring current decay.
