August marked a significant transition for ACEAS as we farewelled our Deputy Director, Professor Nerilie Abram (Australian National University), who has stepped into the nationally significant role of Chief Scientist at the Australian Antarctic Division (AAD).

Since ACEAS’s inception, Nerilie’s insight, collegiality and clear thinking have shaped our work. We are excited to see another world-leading scientist take on the AAD Chief Scientist role and look forward to working with her toward a stronger Antarctic program in Australia. Thank you, Nerilie.

With Nerilie’s departure, we warmly welcome Professor Paul Tregoning as our new Deputy Director from Australian National University (ANU).

Professor Tregoning is a geophysicist who uses space-geodetic observations to study changes in the Earth caused by different geophysical processes such as tectonic deformation, climate-driven variations in sea level and polar ice caps, tidal deformation etc. His research over the past two decades has included studies of:

• Inter-seismic strain accumulation in active tectonic regions
• Present-day sea level variations around the Australian coastline
• Hydrological processes and the ocean/continent exchange of water
• Mass balance changes in polar regions
• The elastic loading of the Earth through atmospheric pressure and hydrological loading processes
• Modelling high-accuracy satellite orbits
• The retardation of signals propagating through the Earth's atmosphere

He is a member of the GRACE-FO space gravity Science Team, a Fellow of the IAG, and was an Editor of Journal of Geophysical Research – Solid Earth (2014–2023).

Professor Tregoning joins our other Deputy Directors, Professor Matt England (University of New South Wales) and Professor Zanna Chase (University of Tasmania), on our Management Committee.
