Summary of Research

    I study how the Universe has been shaped over cosmic time. My research focuses primarily on magnetized plasmas associated with galaxy clusters and galaxy filaments, while also encompassing related boundary fields such as galaxy formation and evolution, and feedback from active galactic nucleus (AGN) jets. I investigate plasma physical processes including shocks, turbulence, magnetic fields, and cosmic rays, using a wide range of approaches, without being restricted to specific methods, such as long-wavelength radio (including VLBI) and X-ray observations, as well as numerical simulations. In recent years, motivated by the discovery of fast radio bursts (FRBs), I have also been engaged in observations of transient objects such as pulsars, magnetars, and long-period transients (LPTs). In addition, I am involved in the development of academic information infrastructure, including AI-based systems, in the context of the international large-scale radio observatory SKAO.
