I am Jieshuang Wang (王界双). I obtained my PhD in 2018 from Nanjing University. I was an Alexander von Humboldt Fellow at Max-Planck-Institute for Nuclear physics in Heidelberg, and now I'm working at Max-Planck-Institute for plasma physics in Garching near Munich. My research interests are high-energy astrophysics with multi-messengers, including cosmic-rays, neutrinos, gravitational waves and their electromagnetic counterparts. I have experiences on analytical modelings, numerical simulations and data analysis.
