Education and Positions

  • Postdoctoral Fellow, Academia Sinica, Institute of Astronomy and Astrophysics (2018~present)
  • Doctor of Philosophy (Astronomy), University of Helsinki (2010~2017)
  • Bachelor/Master of Science (Astronomy), University of Helsinki (2004~2010)

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.
