Research Interests

My research interests are three-fold, comprised of (1) field-related petrological studies, (2) experimental petrology, and (3) archaeometry. Field-related petrological studies focus on igneous and metamorphic rocks from world-wide localities, including Germany, Namibia/Angola, Australia, Samos, Greece, Rogaland, Norway, and Syria/Turkey. Related experimental studies are mainly concerned with fluid-rock interaction processes on the micro- to nanoscale. Archaeometric projects focus on Aramaic sculptures and ancient ceramic production of Turkey/Syria.
