Ramzi Touchan is a Research Professor in the Laboratory of Tree-Ring Research and a
Professor in the School of Natural Resources and Environment at the University of Arizona. His field of expertise is
developing long tree-ring chronologies to reconstruct past climate in different parts of the world.
programs include establishing a multi-century network of climate records for the eastern Mediterranean and North
Africa based on tree rings by extending and enhancing existing tree-ring datasets, and by developing new tree-ring
chronologies geographically and temporally. This network is being used to study inter-annual to century scale climate
fluctuations in the region and their links to large-scale patterns of climate variability.
