Biographical details

I obtained my PhD degree in 2006 from National Astronomical Observatories, CAS (NAOC), and spent one year at Max-Planck Institute for Radioastronomy as a postdoc working for SKADS. Since 2007, I have been working at NAOC as a staff member until I moved to Australia in 2011.

Research interests

  • Galactic interstellar medium. Our Galaxy hosts both large scale regular magnetic field and small scale turbulent field. The relativistic electrons spiralling the field generate synchrotron emission which is highly polarized. The magnetized ionized gas introduces Faraday effect which can smear out the polarized emission to a large extent depending on the observation wavelength. The propagation of cosmic ray particles is also influenced by the Galactic magnetic field. What is the configuration of the large-scale field? What is the fluctuation properties of the small scale field? Is it Kolmogorov-like? How it is compared to the regular field? What is the scale height of the thermal gas? How to put everything together to explain observations?
  • Radio continuum survey. The continuum survey is essential to investigate the Galactic interstellar medium. I have participated in the Sino-German 6 cm polarization of the Galactic plane which was finished in 2010. I'm now working on single dish survey data such as GMIMS.
