Research Interests

How stars like the Sun and planets like the Earth are formed? In order to answer this question, I have been using radio telescopes, particularly radio interferometers, to observe nearby star and planet forming regions. Radio interferometers allow us to observe fine structures of dense cores and disks where stars and planets form. In order to have better observational tools, I also have been working to build radio telescopes (Submillimeter Array and Atacama Millimeter and Submillimeter Array). My near future goal is to image protoplanetary disks at a resolution of 0.01”. I have started an ALMA Large Program "Early Planet Formation in Embedded Disks (eDisk)" since 2019.
