I combine field and laboratory studies to understand the origin of Earth's continental crust, its composition and architecture. Within this broad research avenue, I concentrate on aspects of continental tectonics with emphasis on Precambrian crustal evolution, old and young orogenic belts, continental extensional tectonics, and the link between orogeny, erosion and sedimentation. With my students and colleagues, we seek to unravel plate tectonics processes around the Eastern Mediterranean with special emphasis on the Cadomian and Avalonian continental collage of SE Europe and Asia Minor, Precambrian crustal evolution of the Arabian-Nubian Shield, the provenance of the great Paleozoic sandstone of northern Africa and Arabia and its linkage to Pan-African orogens.

My research involves the application of trace-element ratios and Sr, Nd, Pb, Mo and Fe isotopic compositions to follow the fate of metals in the environment, in archaeological artifacts and in humans. The clean lab and our sensitive analytical instruments enable me and my students to study small-samples and/or materials with low elemental concentrations (e.g., dust samples, teeth and brain). Currently, my group is involved in research projects centering around:

1.     Records of aeolian, fluvial and lacustrine sediments as tracers of paleo-environment conditions and sediment sources.

2.     Tracing metal artifacts in antiquity.

3.     The dark side of ancient metallurgy: Measuring toxic metals and metallic isotopes (and aDNA) in human populations and in artifacts to trace the impact of early industries through time.

4. The association between elemental anomalies in the human brain and mental diseases.

We carry out these projects in collaboration with researchers from the Hebrew University (Earth Science, Archaeology, Medicine), the Geological Survey of Israel, Israel Oceanographic and Limnological Research, The Israel Antiquities Authority, Tel Aviv University, Haifa University, GFZ - Potsdam, Germany, Columbia University, University of California San Diego, University of Michigan, and the Institute of Geology and Geophysics, Chinese Academy of Sciences.
