Research Interest: Turbulence from space (~AU) to cosmological level (Mpcs)
Selected Notable Research Items:
Velocity Gradient Technique (VGT, e.g. [block averaging, velocity channel or a theory of VGT])
Differential Measure Analysis (DMA)
Velocity Decomposition Algorithm (VDA)
Statistical Methods of turbulence diagnostics (e.g. SPA+, y-parameter method or curvature)
Interstellar Media (ISM, e.g. our review) & Cosmic Rays Feedback (e.g. CR energization)
Fundamental MHD turbulence theory (e.g. Mode leakage, turbulence decorrelation or kinetic turbulence excess)
Space Turbulence (e.g, Alfvenic turbulence or compressible turbulence observation)
