　　Abstract: 

　　In this talk, I will briefly introduce the research activities in our groups in NTHU and my tasks here, covering the fields of galaxy and exoplanet. The research on galaxy study the dynamics of merging galaxy and stars around supermassive blackholes. In the field of exoplanet, we study 1) use transit time variation to find additional exoplanets; 2) the role of aerodynamic drag on the resonant trans-Neptune objects; and 3) the dynamics of both the gas and dust in circumstellar disks, and the interaction between the disk-planet interaction. Finally, I will introduce the role I filled in NIAOT HiRCI （High-Resolution & Contrast Imaging） group - characterizing the imaged objects based on evolution tracks and model photospheres.  

　　All are welcome!
