Hrvoje Tkalčić

Professor Hrvoje Tkalčić is a renowned geophysicist at The Australian National University's Research School of Earth Sciences, specializing in global seismology and deep Earth structure. As Head of Geophysics and Director of the Warramunga Seismic & Infrasound Facility, he leads research into Earth's core-mantle dynamics, planetary seismology, and seismic source physics. His work integrates advanced observational techniques and computational models to explore Earth's interior and other planetary bodies.

• Affiliations: ANU since 2007; Elected Fellow of the Australian Academy of Science (2024); Member of the IUGG/IASPEI Executive Committee (2023–2027).
• Education: PhD in Geophysics from UC Berkeley (2001); Diploma in Physics from University of Zagreb (1996).

Research Interests: Focus on the Earth's inner core anisotropy, planetary core imaging, and lithospheric structure using seismic and correlation wavefields. Recent breakthroughs include discoveries of distinct anisotropy in the innermost inner core and Mars' core structure using InSight mission data.

Grants & Awards: Recipient of the 2023 CAS Distinguished Scientist Fellowship, Royal Astronomical Society Price Medal (2022), and multiple ARC grants. His team's work has advanced seismic inversion techniques and global core-mantle boundary imaging.

Labs/Teams: Leads the Warramunga Array Facility and collaborates with international teams on Mars seismology (InSight) and Antarctic seismic deployments. Supervises a dynamic group of PhD students and postdocs exploring Earth's deep structure and planetary processes.
