Eline M. J. Schotsmans is a post-doctoral researcher in forensic archaeology and taphonomy at the Laboratory of Anthropology of Past and Present Populations (PACEA) at the University of Bordeaux, France, and an honorary fellow at the University of Bradford, UK. She has worked on various forensic cases and conducts research in taphonomy that lies at the interface between archaeo-anthropology and forensic sciences.

Nicholas Márquez-Grant is a Lecturer in Forensic Anthropology and Course Director MSc in Forensic Archaeology and Anthropology at Cranfield University, UK. He is also a Research Associate at the University of Oxford. He has analysed human remains from a number of countries and chronological periods and currently undertakes forensic casework in the UK.

Shari Forbes is a Professor and ARC Future Fellow in the Centre for Forensic Science at the University of Technology Sydney. She is also the Director of the Australian Facility for Taphonomic Experimental Research (AFTER), the first facility in Australia that allows scientists to study the decomposition of human cadavers. She is regularly consulted on forensic casework and assists police to search for and locate human remains using police dogs and geophysical equipment.
