About me

Hi, welcome to my homepage. I am currently a PhD student working in astronomy. I become a member of the Chris Ormel group in Department of Astronomy, Tsinghua University, China since 2021. My research interests lie on studying planet formation with hydrodynamic simulations. Esspecially in,

  • Planet-disk recycling flows in protoplanetary disks;
  • Volatile delivery to young planets by pebbles;
These topics help us understand questions like, the mysterious origin of water on Earth, the diversity of water content of exoplanets and the role of volatiles during planet/planetesimal formation etc. Connecting results from hydro simulation to observational signatures would also be the topic I would like to learn and explore.

I usually use the famous MHD code Athena++ in my research and try to develop new modules adding new physical processes, e.g, phase change (sublimation/condensation), into it. It would be super interesting if you have any ideas related to the phase change process so feel free to contact me.
