Research Interests

My research interest is star and planet formation, and the goal is to understand the origin of our solar system and the diverse properties of exoplanetary systems. I use various radio telescopes, such as ALMA, SMA, IRAM 30m and JCMT, to observe the gas kinematics in star-forming regions and protoplanetary disks. My recent projects are to investigate the role of the magnetic field in star forming regions and to search for young planets in protoplanetary disks by analyzing the gas kinematics. We are looking for graduate or undergraduate students to join our research group.
