Rate My Professor Hamed Gamaleldien

Dr. Hamed Gamaleldien serves as an Adjunct Research Fellow in the School of Earth and Planetary Sciences, Faculty of Science and Engineering, at Curtin University. He earned his PhD in Applied Geology from Curtin University in March 2021, specializing in mantle chemical dynamics. His doctoral thesis was awarded the Krishna & Pamela Sappal Prize for the best doctoral thesis in 2021 at the School of Earth and Planetary Sciences, recognizing his exceptional research on geochemical signatures of the deep mantle that unraveled the tectonic history of the Arabian-Nubian Shield and mantle dynamics. Following his PhD, he held a Research Fellow position in the same school from November 2020 to August 2023, prior to his current adjunct role starting in August 2023. Earlier in his academic career, he studied Geology at Tanta University from January 2010 to February 2013.

Gamaleldien's research focuses on utilizing advanced geochemical techniques to investigate mantle- and crust-derived rocks across global, regional, and micro- to nano-scales, providing insights into Earth's dynamic evolution over its four-billion-year history. This includes the development of the mantle, paleohydrosphere, early continental crust, onset of plate tectonics, superplume-supercontinent cycles, and critical metal formation. His main academic interests encompass early Earth crustal evolution, mantle chemical geodynamics, subduction zone geochemical cycles and related mineralization, and critical metals formation. Key publications include "Cr-spinel records metasomatism not petrogenesis of mantle rocks" (Nature Communications, 2019), "The largest plagiogranite on Earth formed by re-melting of juvenile proto-continental crust" (Communications Earth & Environment, 2021), "Potassium isotopes trace the formation of juvenile continental crust" (2024), "Onset of the Earth’s hydrological cycle four billion years ago or earlier" (2024), and "Iron and zinc isotopes constrain the continental crust formation" (2025). As lead author on the 2024 study examining zircon crystals from Western Australia's Jack Hills, he identified light oxygen isotopic signatures indicating hot fresh water alteration deep in the crust approximately four billion years ago, suggesting early landmasses and hydrological processes that set the stage for life.
