Bio
Very long baseline interferometry (VLBI) can achieve microarcsecond accurate (differential) astrometry, which has many unique and key astrophysical applications. Meanwhile, geodetic and (absolute) astrometric VLBI is unique in the establishment of the terrestrial reference frame (TRF), the celestial reference frame (CRF), and the earth orientation parameters (EOPs). My research interests cover both fields and include (1) new techniques/methods to improve VLBI astrometric capability/accuracy, such as accurate phase calibration, astrometry with multi-frequency/beam, geodetic VLBI at high frequency; and (2) their astrophysical applications, such as the mass-loss process of evolved stars, Galactic structure, frequency-dependent position difference of quasars and stars (multiple radio bands & Gaia). In addition, I am a crucial member in improving the astrometry performance of the East Asian VLBI Network (EAVN).
