                                   RESEARCH                                    

    I work with solar system research, a very fascinating subject and full of unsolved questions and interesting mysteries. My main research interests are:
  • Origin and evolution of the Solar System
  • Physics and dynamics of trans-neptunian objects - TNOs (or Edgeworth-Kuiper belt objects - KBOs), asteroids, Centaurs, Trojans, comets, and other minor bodies
  • Terrestrial and giant planet formation
  • Planet migration
  • Orbital resonances

                           Outreach and public releases                         

    • "By Jupiter: the gas giant's Trojans were captured, not pre-formed" published in the Australian news THE CONVERSATION, based on the Jupiter and Neptune Trojans research
Link
    • "Trojans may yet rain down" published in Universe Today, based on the Neptune Trojans and comets research
Link
    • "Cosmic Trojans may sneak comets towards Earth" published in New Scientist, based on the Neptune Trojans and comets research
Link
    • "Searching for a hypothetical trans-neptunian planet - the 9th solar system planet candidate" published in SANKEI NEWS (in Japanese), based on the outer planet research
Link
    • "Science vs. pseudoscience in the solar system" broardcast by the Korean SBS TV channel, cited the outer planet research among the latest solar system science hot topics
    • "An unknown planet in the outskirts of the solar system?" press conferences held at Kobe University and the National Observatory of Japan, based on the outer planet research. Subsequently, more than 100 articles were published in news and magazines about solar system and Kuiper belt science and the existence of hypothetical trans-neptunian planets around the world. Please refer to my CV for more details and links
    • For details about other outreach and public activities, please refer to my CV
