Professor Henk Kars has a background in mineralogy, petrology and geochemistry. After having finished his PhD Early-Medieval Dorestad, an Archaeo-Petrological Study, he performed between 1984-1994, in close cooperation with specialists in different areas of science, a variety of archeometric studies in the fields of provenancing (stone, ceramics), ancient technology (iron production), dating (geomagnetism, 14C, dendrochronology) and (geochemical) prospection, which has ... Read moreresulted in a high number of papers in international, often peer-reviewed, journals. Since 1995 the research subjects changed from main stream science in archaeology to the in situ preservation of archaeological heritage. This is demonstrated by the participation and coordination of EC-projects that studied the in situ deterioration of the metal artifact, bone and wood. Today he is an internationally acknowledged expert with regard to the preservation ofarcheological remains in situ. In addition to this he has been member of the management team of the Dutch National Service for Archaeological Heritage (ROB) for more than five years. His career at Vrije Universiteit Amsterdam (VU) started in 1994 where he was appointed, on a part time basis, to the first chair of Archaeometry in the Netherlands. In 1997 he became director of the post-academic course "Management van Archeologische Projecten" (projectmanagement for archaeologists), which is performed within a partnership of both universities of Amsterdam and ROB. Since 2002 he has been a fulltime professor Geo- en Bioarchaeology at the VU and director of the newly established Institute for Geo- and Bioarchaeology. Lida van den Eijkel (MSc) studied Environmental Sciences at Wageningen University, a comprehensive education in both the biotic and the abiotic environment. She specialized in soil and water pollution, with strong emphasis on microbiology and physical chemistry. Part of her education was a 6 month stay in Siberia to study the hydrobiology and pollution of Lake Baikal (at the University of Irkutsk and Limnological Instiute of the Academy of Sciences).After graduating she worked for consultancies on projects of soil remediation (especially cases of metal pollution), for a company that developed (superconducting) magnetic systems as a clean-up technology for waste water and soil, and for the (now) Ministry of Infrastructure and the Environment (Rijkswaterstaat) on the pollution of flood plains.She moved to the Netherlands Forensic Institute more than 25 years ago to work with the new to be established department of Environmental Forensics, in the beginning doing pioneering organizational work as well as forensic case-work with regards to the enforcement of environmental laws in The Netherlands. Later she extended the case-work to criminal law enforcement, examining especially soil and water contact traces.In recent years she concentrated on environmental forensics again. Fields of special interest and work are the use of data collections of soil characteristics, the application of (recycled) materials as fertilizers, care duty for soil and GIS. An emerging field of work is the water and soil pollution due to organized serious crime, such as the delibarate dumping in the environment of waste resulting from the production of illicit drugs.
