Biography
Dr Hoogewerff studied geochemistry (M.Sc.) and volcanology (Ph.D.) at the University of Utrecht in the Netherlands (1984-1993). The emphasis of his work was, and still is, using geochemical analysis to trace natural materials to their geographical origin.
During his PhD research he investigated the contribution of the Australian crust to volcanism in Eastern Indonesia. In 1993 Dr Hoogewerff joined the Department of Health Sciences of University Maastricht to teach environmental sciences and develop tracers for the origin of pollutants from their source to environmental and biological targets including human tissues. Dr Hoogewerff transferred to the Geotechnical Institute Arsenal Research in Vienna in 1996 where he continued his environmental exposure research, combining epidemiological data with newly created geochemical maps. Here he also started to apply his techniques for forensic casework and archaeological provenancing. His study on 5000 year old "Otzi" was the first isotope provenancing study on the Tyrolean Iceman.
With an EU grant in 1999 Dr Hoogewerff established the global analytical forensic network NITECRIME that included major national forensic research institutes like the NFI, BKA, US Customs and FBI. In 2006 NITECRIME almagated with the Forensic Isotope Ratio Mass Spectrometry network and Dr Hoogewerff was involved in its management until 2014. In 2000 Dr Hoogewerff moved to the Institute of Food Research in Norwich to manage their isotope facility for food forensics applications and human metabolism studies. Together with other colleagues he initiated the EU funded TRACE project (Euro20M) using the compositional links between soil and food for determining the geographical origin of food products to combat counterfeiting.
Dr Hoogewerff was Senior Lecturer at the University of East Anglia in Norwich UK from 2006 to 2011 and developed and managed their "Forensic and Investigative Chemistry" four-year MChem program. In September 2011 he relocated to Dunedin in New Zealand and first served one year as part-time Chief Scientist and Co-Director of Oritain Ltd. and then continued as Associate Professor in the Department of Chemistry at the University of Otago to expand their Forensic Analytical Science Program until December 2014.
In January 2015 Dr Hoogewerff moved to UC, to join the National Centre for Forensic Studies NCFS (Director 2019-2023) where he convened a number of on-campus and online units e.g. “Environmental and Forensic Geochemistry” and “Forensic Chemistry” and was the course convener of the Online Forensic Science MSc until the NCFS closed down in 2023.
Currently Dr Hoogewerff is the lead of the System Ecology Capability with 20+ staff in the Faculty of Science and Technology, and responsible for the forensic and environmental geochemistry research and a well-equipped analytical laboratory. Dr Hoogewerff convenes 2nd year’s Environmental Tools and Technologies field-based unit and the lab-based 3rd year Chemical Applications unit, focussing on field sampling, analysis and mapping of environmental pollutants like heavy metals, nutrients and microplastics and their possible effects on local ecology.
Current main research focus and funding is on developing new methods to analyse microplastic in water and sediments, to support “forensic” mapping of microplastic distribution and sources in the Canberra region, to assist policymakers with spatial data to reduce plastic inputs in the environment.
An additional recent research interest is the acoustic monitoring of flies and general insect activity in nature reserves and waterways, based on the experience gathered from a PhD project on monitoring fly activity and succession on human remains for Time of Death estimation, using ample recording and machine learning data analysis.
Dr. Hoogewerff is actively engaged in forensic casework and contributed to 80+ scientific papers and over 80 conference presentations including many invited keynotes, and currently has a Scopus h-index of 41 (June24).
Current research interests
- Creation of geochemical maps for environmental and forensic applications.
- The transfer and persistence of particles in forensic and environmental applications.
- Analysis of micro-plastics in soil, water and animal tissues.
- Ecoacoustics and machine learning.
