Biography Hrvoje Tkalčić studied physics and geophysics at the University of Zagreb (Faculty of Science), from which he gained a Diploma of Engineering in Physics degree (speciality in Geophysics with meteorology) in 1996. He continued his postgraduate study at the University of California at Berkeley in the Department of Earth and Planetary Science, and defended a PhD thesis entitled Study of deep Earth structure using seismic body waves in 2001.Who is Who in Croatian Science: Hrvoje Tkalčić – Education. Retrieved 24 February 2018. He was employed as a research assistant at the UC Berkeley Seismological Laboratory (1997–2001), as a postdoctoral fellow at the Institute of Geophysics and Planetary Physics of the University of California San Diego (2002–2003), and as a postdoctoral researcher at Lawrence Livermore National Laboratory in Livermore, California (2003–2006). In 2006, he began a continuing position as Scientist in the Seismology group at Multimax, Inc., in Emeryville, California. From January 2007 until April 2013, he was a Fellow at the Research School of Earth Sciences (RSES) of the Australian National University (ANU), Canberra, Australia. From April 2013 until December 2018, he was a Senior Fellow and associate professor in Seismology and Mathematical Geophysics at RSES, ANU. He was Head of Seismology and Mathematical Geophysics from January 2017 to April 2021 and Professor E1 from January 2019 to June 2023. He has been Head of the Geophysics Area since April 2021 and Professor E2 since June 2023.Who is Who in Croatian Science: Hrvoje Tkalčić – Employment. Retrieved 24 February 2018.
He has published 130 papers in peer-review journals in the field of seismology and mathematical geophysics,Australian National University, Canberra – ResearchGate: Hrvoje Tkalčić Retrieved 4 December 2020. and an academic book on the Earth's inner core.Cambridge University Press – The Earth's Inner Core. Retrieved 4 December 2020. His primary research interests involve studying Earth's structure and dynamics using state-of-the-art seismological techniques, with the main focus on the Earth's core and the lowermost mantle, and developing new techniques for imaging Earth's interior, including both seismic and correlation wavefield. Other interests include studying the physics of tectonic and volcanic earthquakes by means of waveform modelling and improving volumetric raypath coverage of the Earth's interior through the installation of seismic instruments in remote parts of the planet, including on the ocean bottom.Tko je tko u hrvatskoj znanosti: Hrvoje Tkalčić – Znanstveni interesi .

He participated in a number of scientific field campaigns to establish temporary seismic networks in remote parts of Australia and the Southern Ocean. The main objective has been to image the structure of the Earth's interior using seismic tomography and other imaging techniques. He actively participates in special sessions at a number of international geophysical conferences.The Australian National University – Research School of Earth Sciences: Hrvoje Tkalčić, Curriculum Vitae .
