PROFESSIONAL PROFILE

Dr Renaud Joannes-Boyau’s research focuses on the development and application of direct dating methods and micro-analytical techniques to key questions in archaeological sciences, such as the timing of human evolution, hominid ecological niche, diet and early life history. His research is concerned with the understanding of mobilisation, incorporation and diffusion of isotopes, trace element and radionuclides onto fossil remains. Renaud has made a significant contribution to geochronology and geochemistry applied to human evolution, with the dating of key fossils (e.g. early Homo sapiens from Jebel Irhoud, Homo naledi..) and the geochemical imaging of extinct hominins.

The paper reported on the new methodological breakthrough allowing the accurate ESR dating of fossil teeth, by unveiling the misinterpretation of the compound ESR signal in the fossil teeth.

(2017). The age of Homo naledi and associated sediments in the Rising Star Cave, South Africa. Elife 6, e24231.JIF 7.725; C 59 LINK

This paper revealed the incredibly young age of Homo naledi fossil remains, and its implication for human evolution theory. The challenging dating of new Homo species led to the development of a new methodological breakthrough.
