Dr. Xing Li was born in the People's Republic of China. He was educated in the University of Science and Technology of China at Hefei and the Harvard-Smithsonian Center for Astrophysics. He got his bachelor's and master's degrees of science in plasma physics. His PhD thesis was about the property of minor ions in the fast solar wind. After he completed his PhD study he worked in the Harvard-Smithsonian Center for Astrophysics as a post doctoral fellow and developed solar wind models (wind driven by turbulence-driven ion-cyclotron waves and 16 moment models).
In March 2001, he was appointed as a lecturer in the physics department. His research interests are the coronal and solar wind physics, various plasma waves and instabilities in space plasma and the corona, and multi-fluid and MHD modeling of the corona and wind. A long standing interest is the heating and acceleration mechanisms of the solar wind. His current research interests are space plasma turbulence at very small scales where energy dissipation of turbulent fluctuations and particle heating are possible.
- Solar Wind Plasma Turbulence:
Coronal heating has been a myth for several decades. The temperature of solar atmosphere at the photo sphere is about only 5000 degrees. However, it reaches about 1 million degree in less than 20000 km above the photosphere. It has long been thought that turbulence plays a key role in the heating of the solar corona and its extension: the solar wind. My main research interest is the analysis of space plasma turbulence using multi-spacecraft data analysing techniques. We use k-filtering and phase-differencing techniques to have close-up snapshots of plasma perturbations in order to understand and better describe the behaviour of turbulent fluctuations at ever small scales
I am also interested in the broad space plasma physics, such as propagation of plasma waves, plasma instabilities.
