Research Interests
Dr Delphine Dissard has recently started a new postdoctoral research position in BioGeochemistry at the University of Western Australia. Her research topic focussed on Paleo pH and ocean acidification (anthropogenic) reconstructions based on Boron isotopes and B/Ca ratios in biogenic carbonates (corals and foraminifera). Having previously completed a Post Doc Position at the Scientific Laboratory for Climate Science and Environment (LSCE-CNRS, Gif-sur-Yvette (Paris)/France) and a PhD at the Alfred Wegener Institute in Germany (AWI Bremerhaven), she has gained a wide range of transferable skills and experience in field work, lab experiments (foraminifera culture, carbonate chemistry sampling DIC, ALK, Boron isotope and B/Ca ratios sample handling, cleaning, and chemical extractions) and analysis (LA-ICPMS, ICP-QMS, MC-ICP-MS, ICP-EOS). Throughout her studies, she developed research skills with particular interest in paleoclimatology, geochemistry, biomineralisation, and calibration of geochemical (and ecological) proxies, an important tool to evaluate the validity of climate change scenarios.
