About me

      Hi there! I am Yun, a postdoctoral researcher at Lagrange Laboratory of CNRS. I am working on an assortment of problems in the context of planetary system formation and evolution.
      In particular, I use state-of-the-art computational tools (such as the high-efficiency parallel tree code pkdgrav) to investigate the evolution of small bodies and support on-going and upcoming small-body space missions and data interpretations. You can find a list of my publications on NASA/ADS or Google Scholar.

Latest Research

      Based on numerical modeling and integration of information from both observations and in-situ detections, my research aims at deciphering the physical properties and evolutionary history of different kinds of small bodies and eventually revealing some aspects on the Solar System evolution. Here are the research topics I am recently or currently dedicated to:

  1. Origin, physical properties, and dynamical evolutions of several small bodies in and beyond the Solar System
  2. Granular dynamics applied to the surface and interior processes of small bodies
  3. Planetesimal evolution at different stages of stellar evolution
