Research Areas

  • Ultrahigh Pressure Mineralogy, Experimental Petrology, Ultra-High Pressure Metamorphism and Deep Subduction, Deep Earths Mineralogy and Geophysics

Research Interests:

The focus of my researches is on solid Earth geophysics. I use mineralogy as tool for studying ultrahigh-pressure metamorphic rocks from collisional orogenic belts, their microstructures, compositions and mineral phase transformations at very high pressures and high temperatures in order to provide understanding of the architecture of the Earth's interior and its geodynamics. It includes also experimental modeling of the ultra-deep metamorphic process and mineral phase transformations utilizing Walker 's style multianvil apparatus and diamond anvil cell devices.  Origin of diamonds from ultra-high pressure metamorphic terranes, deep subduction of continental crust. Experimental synthesis of diamonds from different source of natural carbon in presence of H2O at high pressures and high temperatures and their implication for geology, geophysics and materials science. My researches combine geological observations and analytical studies of minerals with advanced electron microscopy and synchrotron assisted micro X-ray and micro IR and Raman spectroscopy and experimental modeling of mineral behaviors at extreme conditions.

Current projects and research opportunities:

1. Nitrides in terrestrial rocks: A window into the geodynamic history of the Earth.

2. Fate of continental crust subducted to Earth's mantle transition zone: experimental studies.

3. Diamond formation in subduction zones; diamond synthesis from a supercritical COH-fluid

4. Nanoscale geological materials – from mineralogy: Focused Ion Beam, nanoSIMS, synchrotron IR and Raman spectroscopy, Scanning and Transmission electron microscopy.
