Research Interests

I am interested in the magnetic turbulence of interstellar medium in all scales, from the supernova driving of galactic dynamo to the relatively small scales of star formation. I also wish to find way to connect theoretical models with observational signatures, and therefore I consider radiative transfer modeling to be an integral part of my work. In addition, I have general interest in the computational methods of astrophysics, particularly using GPUs.
