Abstract: The CUHK star formation group was founded in 2014 and uses all the major astronomical tools to study star formation. The close collaboration between observers, theorists and instrumentalists allows us to uncover new insights into the interactions between gravity, turbulence and magnetic fields. I will briefly introduce the new tools we developed (a submm imaging polarimeter, a MHD code and some new observational strategies) and, based on which, the discoveries on field-density relation (Zeeman measurements), turbulence anisotropy and ambipolar diffusion.

Bio: Hua-bai Li was born in Taipei, Taiwan, China, in 1974. He received the Ph.D. degree in astrophysics from Northwestern University in 2006. Afterwards, he worked in the Harvard-Smithsonian Center for Astrophysics and Max Planck Institute for Astronomy. In August 2013, he started his professorship in the Department of Physics, The Chinese University of Hong Kong. His research group studies how magnetic fields and turbulence regulate star formation; they use various novel methods in observations, numerical simulations and instrumentation.
