My research focuses on space plasma physics and solar physics, with particular emphasis on solar wind turbulence, magnetic reconnection, and the origin of solar wind. My recent work focuses on three areas: (1) analyzing satellite observations from missions such as Parker Solar Probe, WIND, and MMS to investigate dynamic processes in the solar wind; (2) developing high-performance magnetohydrodynamic (MHD) simulation codes to study plasma turbulence, magnetic reconnection, and solar wind dynamics; and (3) advancing fundamental theories on current sheet instabilities, solar wind generation, and MHD turbulence. In addition, I am interested in applying machine learning techniques to predict space weather from remote-sensing observations of the Sun.
