Welcome to my research webpage! I’m Jiaqing Bi (毕嘉擎).

I am a postdoctoral fellow at the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA). Currently, I am temporarily based at the University of Toronto.

I obtained my Ph.D. (in 2023) and M.S. degrees in Astronomy from the University of Victoria in Canada, advised by Dr. Ruobing Dong. Before that, I obtained my B.S. degree in Physics (Honors Program) from Xi’an Jiaotong University in China.

My research aims to better understand how planets form in circumstellar disks. To be more specific, I focus on the dust dynamics under planet-disk interactions, binary-disk interactions, stellar radiation, and so on. I study this topic from both theoretical and observational approaches. I build disk models with 3D grid-based hydrodynamic codes (e.g., FARGO3D) and a GPU particle code developed by myself (see Bi & Fung 2022). I also work with submillimeter interferometry data from ALMA. For more details on my research activities, please refer to my publications.
