Dr Jens Holtvoeth joined FIDELIO as a research associate in January 2020 working on the collection and modelling of secondary environmental data and supporting also the organisation of social surveys in European national parks.

Jens was awarded a PhD in Geosciences in 2004 by the University of Bremen, Germany, and has since worked in the fields of paleoclimatology and environmental geosciences, mainly on ecosystem adaptation to past climate change. He has been a postdoctoral researcher at the Woods Hole Oceanographic Institution and at Liverpool University and, from 2014 to 2019, a lecturer at Bristol University, teaching a range of environmental subjects, from the global carbon cycle to analytical geochemistry, as well as being a personal tutor and supervising BSc and MSc projects. 

Jens’ research has targeted, for example, past changes in sea surface temperature in the North Atlantic, the effects of oceanic iron fertilisation on deep-sea ecosystems and the geochemical fingerprint of soil organic matter in lake sediments. Prior to his academic career, Jens gained substantial experience in site investigation, working freelance in environmental consultancy. In 2014, he became involved in an interdisciplinary project with Dr Nikoleta Jones and Dr Chrisovaladis Malesios, among others, on the local population’s perception of severe environmental pollution in a Greek river catchment. This successful collaboration is now continued in FIDELIO.
