I was born in Xi'an, China, and came to UCLA to study space physics. Now I live with my wife and son in Los Angeles.
  • Education
    • Ph.D. in Space Physics, University of California, Los Angeles, Oct. 2013
    • M.S. in Space Physics, University of California, Los Angeles, Jun. 2010
    • B.S. in Space Physics, Peking University, Jul. 2007
  • Professional Activities
    • Principal Investigator for NASA's Heliophysics Guest Investigator program.
    • Chair and Convener for AGU Fall meeting sessions.
    • Referee for Nature Physics, Journal of Geophysical Research - Space Physics, Geophysical Research Letters, Annales Geophysicae, Advances in Space Research, Planetary and Space Science, Science China Earth Sciences, and NASA H-GI proposals.
    • Tohban (duty officer) of NASA's THEMIS mission


My research interest covers the Earth's magnetosphere and ionosphere, and outer planets' magnetosphere. My research focuses on:

  • Transient energy carriers at the dayside magnetopause and in the magnetotail, especially their role in global energy transport during geomagnetic storms and substorms.
  • How the current system of the magnetosphere and the ionosphere change in response to geomagnetic activities.
  • I investigate these subjects using data from THEMIS, Van Allen Probes, MMS, and Cassini missions.

    In addition, I simulate the response of the Energetic Particle Detector onboard the Electron Losses and Fields Investigation (ELFIN) CubeSat and participate in the Europa Clipper misson.


    I enjoy reading comic books, playing video games, and building model kits. Building model kits is an art; finished kits are pieces of art, not toys. My training in fine art 20 years ago allows me to be proficient at model kit building.
