Sabine Klein studied mineralogy with a focus on economic geology, petrology and geochemistry. This was followed by a doctorate on early medieval bronze metal slags from the Höxter/Corvey area at Goethe University in Frankfurt. A research grant from the Volkswagen Foundation enabled a one-year stay at the National Institute of Standards and Technology (NIST) in Gaithersburg, MD, and a second year at the Massachusetts Institute of Technology (MIT) in Cambridge, MD, USA. Back in Germany as a postdoctoral fellow in the Frankfurt Research School "Archaeological Analytics", her research preference for archaeometry solidified, and she finally habilitated in 2008 with a numismatically oriented archaeometallurgical thesis on "The Copper of the Roman Imperial Period and its Raw Material Sources". With the award of the Venia Legendi for Mineralogy and Archaeometry, she was granted the authorization to teach at Goethe University. Since 2016, she has been head of the research area of archaeometallurgy at the German Mining Museum Bochum and professor at RUB. Her expertise is in mineralogy, ore geology, archaeometallurgy, archaeometry, materials science, applied geochemistry and isotope applications. She is experienced in the study of all types of inorganic objects such as metal, ceramics, glass and glazes, slags and metallurgical remains.
