Lucia McCallum

Dr. Lucia McCallum is a Senior Lecturer in Geodetic VLBI at the School of Natural Sciences, Physics, University of Tasmania. She specializes in Very Long Baseline Interferometry (VLBI) for Earth observation, focusing on measuring the Earth's shape, rotation, polar motion, and plate tectonics. Her work connects geodetic techniques (GNSS, SLR, VLBI) via space tie satellites, with leadership in the ARC DECRA-funded project and the AuScope VLBI collaboration with Geoscience Australia.

• PhD from Technische Universität Vienna
• Active since 2014 in UTAS radio astronomy group

Her research bridges geodesy and astrophysics, advancing the next-generation VLBI Global Observing System (VGOS) for millimeter-level precision. This technology addresses critical geoscientific challenges like sea level rise prediction and terrestrial reference frame stability.

Recent publications (2025-2014) span VGOS optimization, GNSS satellite tracking, atmospheric signal corrections, and space tie methodologies. Her work emphasizes international collaboration through the International VLBI Service for Geodesy and Astrometry (IVS) and leadership roles in the Asian Oceania VLBI Group (AOV) and IVS Working Group 7.
