معرفی
Prof David Dobson is a Professor of Earth Materials at the Department of Earth Sciences, University College London. He leads research on high-pressure Earth materials, particularly focusing on deep Earth core-mantle dynamics. His work utilizes advanced facilities like multi-anvil presses and diamond cells to study mineral phase transitions under extreme conditions.
Research interests include Earth's core alloy composition, mantle transport properties, and the mechanical behavior of deep-Earth minerals. Key areas of exploration involve high-pressure experiments on Fe-alloy phases, seismic anisotropy in the D'' layer, and the kinetics of mantle phase transitions.
Recent experimental studies investigate grain boundary dynamics in olivine aggregates, melt viscosity effects in subduction zones, and frictional melting mechanisms in transition zone earthquakes. His work bridges mineral physics with global geodynamic modeling, contributing to seismic and thermal interpretations of Earth's interior.
Prof Dobson teaches GEOL0039 (Earth and Planetary System Science) and GEOL0023 (Crustal Dynamics and Mountain Building), integrating experimental mineral physics with geological processes.
His lab operates state-of-the-art high-pressure apparatus including modified Paris-Edinburgh cells and deformation multi-anvil presses at synchrotron facilities, enabling in-situ observations of mineral phase behavior under mantle conditions. Collaborations include the Bayerisches Geoinstitut and international neutron diffraction studies.
