Thibaut Cossart is a PhD student in Environmental Science at the University of Geneva, Switzerland. He has an MSc in Marine Biodiversity and Biomolecules from the University of Toulon, France. His research is focused on the interactions between phytoplankton and mercury. He highlighted the role of phytoplankton in the biogeochemical cycle of mercury by (i) evaluating the biotic transformations performed by a cyanobacterium and natural phytoplankton communities and (ii) determining the effects of thiol bioligands on the bioaccumulation of Hg species by cyanobacteria. |
Javier García Calleja is a PhD student in the Amouroux lab at the IPREM, CNRS-UPPA, Pau, France. He holds a BSc in Chemistry and a MSc in Analytical and Bioanalytical Chemistry from the University of Oviedo, Spain. His research includes (i) development of mathematical approaches based on isotope pattern deconvolution for studying Hg compound reactivity in in situ Hg incubation experiments and (ii) characterisation of bioligands involved in Hg speciation in phytoplankton by hyphenated techniques based on elemental and mass spectrometry. |
João P. Santos holds a BSc in Biology, an MSc in Ecology, Environment and Landscape and an MSc in Marine Sciences from the University of Porto, Portugal. He worked with the nitrogen cycle communities until he started his PhD. Currently, he is a PhD student in the Slaveykova’s lab at the University of Geneva, Switzerland. He studies the interaction of diatoms and natural phytoplankton communities with different mercury species, and explores their capability to accumulate, transform and detoxify mercury. |
Dr Elaheh Lotfi Kalahroodi is a postdoctoral researcher in Environmental Geochemistry at the Umeå University in Sweden. Her research is focused on studies of the biogeochemical mechanisms of organic and inorganic contaminants in the environment through isotope fractionation of stable non-traditional isotopes. She evaluates and optimises methodologies to trace and quantify the spread of Hg from contaminated sediment sites to surrounding sediment and pelagic and benthic biota using Hg stable isotope measurements. |
Dr Isabelle A. M. Worms is a senior scientist of environmental biogeochemistry and ecotoxicology at the University of Geneva. She is a biochemist with a MSc in Molecular Chemistry. Since her PhD, her research interests include (i) understanding the bioavailability of trace metals, (ii) developing AF4-ICP-MS to assess the role of natural organic matter on the binding and dispersion of trace metals in surface water and (iii) identifying key processes involved in nanoparticle stability using quantitative approaches. |
Dr Zoyne Pedrero ZAYAS is a research scientist at the French CNRS appointed at IPREM, CNRS-UPPA. She is an analytical chemist and her work principally focuses on metal speciation (mainly Hg and Se) by hyphenated chromatography based separation mass spectrometry techniques and isotopic analyses in living organisms. Her research interest comprises, among others, the interaction of Hg and Se in biota as well as pollution sources and metabolic processes tracking. |
Dr David Amouroux is a research director at the French CNRS appointed at IPREM, CNRS-UPPA. He is responsible of the Research Unit for Environmental Chemistry and Microbiology. He is an environmental and analytical chemist, specifically interested in the cycling and reactivity of contaminants in the environment. Some of his research lines include: (i) transformations and transfer of mercury, selenium and other metal(loid)s at aquatic environment interfaces and (ii) development of analytical and experimental methods using stable isotopes of trace elements to investigate biogeochemical mechanisms in the environment. |
Dr Vera I. Slaveykova is a full professor at the University of Geneva and president of the School of Earth and Environment Sciences. She works on the development of concepts and tools for a better understanding of the fundamental processes governing the behaviour and impact of trace elements and nanoparticles in the aquatic environments. Her current research interests and portfolio include (i) speciation and bioavailability of trace elements, and nanoparticles in the aquatic environment and (ii) aquatic toxicology of inorganic contaminants and nanoparticles; transcriptomics and metabolomics. |
