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.

Research

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.

    Interests/Hobbies

    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.
