Research Interests

• Tectonometamorphic evolution of orogenic belts and continental margins, and reconstructing the P-T-time history of metamorphic rocks. These studies involve field mapping, mineral analysis, application of geothermobarometers, phase equilibria, and a variety of geochronological techniques to metamorphic rocks to develop a tectonic model for the area studied.
• Fluid – rock interaction, with special emphasis on the role of fluids in metamorphism and ore genesis (particularly in subduction zone settings).
• Retrieval and assessment of the thermodynamic data of minerals, construction of petrogenetic grids.

Previous Research Projects

• Granulite facies metamorphism and partial melting in the Central Blue Ridge Province, Southern Appalachians
• Origin of Banded Iron Ores, Central eastern Desert of Egypt.
• Petrogenesis of mesothermal Au vein deposits, Egyptian Eastern Desert
• High pressure metamorphism and tectonic evolution of the continental margin of Oman

Current Research Projects

• Tectonometamorphic evolution of the Blue Ridge Province, Southern Appalachian Mountains
• Rare Earth Element Abundance and Distribution in WV Shales, Fireclays, and Tonsteins
• Garnet zoning patterns in blueschists and eclogites from Oman
