Science Interests: Galaxies and supermassive black holes, jets and outflows. Active Galactic Nuclei studies using Very Long Baseline Interferometry, in particular the VLBI kinematics and the multi-wavelength studies (radio/optical/X-ray/gamma-ray) on AGN inner-jet. M87 jet dynamics.
Technical interests: VLBI wide-fied imaging, high-dynamical-range interferometric imaging, mm/sub-mm data calibration, single-dish data calibration and imaging.
