Dr Jasmine Nahrgang is an ecotoxicologist at the University of Tromsø and project leader of two Norwegian Research Council funded projects (POLARISATION and COOPENOR, https://site.uit.no/coopenor). She has worked in the last 6 years on the effects of oil pollution on Arctic marine species through both experimental and field based studies. During her researcher position at APN, she focused on seasonal variations of biomarkers in field sampled Arctic and sub-Arctic organisms (bivalves and fish) as well as the optimization of toxicity tests for Arctic organisms. In her present position at the University of Tromsø, Dr Nahrgang continues studying the effects of oil contaminants on Arctic species, especially focusing on metabolic functions crucial during their life cycle such as the lipid homeostasis through POLARISATION. Dr Nahrgang´s research interest also include ecological and physiological studies of Arctic organisms and their response to combined natural and anthropogenic stressors. Dr Nahrgang is responsible for ecotoxicological courses at both Bachelor and Master levels at the University of Tromsø and the implementation of a ecotoxicological study programme focused towards the High North. She is supervising 2 PhD students and several Master and Bachelor students.
Ireen Vieweg is PhD-candidate at the Institute for Arctic and Marine Biology at the University of Tromsø, Norway. She has a Master of Science in Marine Biology from the University of Bremen (Germany). Next to her studies, she has worked as research assistant at the Max Planck Institute for Marine Microbiology in Bremen (Germany) and gained a good knowledge of molecular methods through this work. In her Master thesis, she studied the effects of environmental factors on the levels of Persistent Organic Pollutants (POPs) in Arctic bivalves from Svalbard. This project was carried out at the Norwegian Polar Institute and more recently, she has been working as research assistant in different projects on Svalbard for the Norwegian Polar Institute. In September 2012, Ireen started her PhD- project as part of the POLARISATION-project and she is going to study the biological effects of polycyclic aromatic hydrocarbons (PAHs) on lipid metabolism in polar cod (Boreogadus saida).
Dr Jordan Nechev is Assistant Professor in Institute of Organic Chemistry at Bulgarian Academy of Sciences, Sofia, Bulgaria. His interests have always been in interdisciplinary approach to organisms’ metabolites, and the factors influencing them – environmental conditions and pollutants. As a result he has a M.S. degree in Biology, and PhD in Organic Chemistry. His work is mostly referred to performance of different extractions from marine benthic invertebrates and their tissues; purification and derivatization of the samples, and their analyses via chromatographic techniques; identification of substances – lipids and some secondary metabolites (sterols, hydrocarbons, volatile and polar compounds), which could be used for chemotaxonomic conclusions, as well as pollutants. In August 2012, he started working on a post-doctoral position, which is part from the “POLARISATION” project at the University of Tromsø. As an integrated member of the project, his work consists of investigating the influence of PAHs in polar cod (Boreogadus saida) including their toxicokinetics, as well as changes in lipid metabolism in the fish.
Morgan Bender is taking a Masters in Biology at UiT with a focus on marine fish ecology. Happy now to be in the warmth of Tromsø, Morgan graduated from the University of Alaska, Fairbanks with two Bachelors degrees, Biological Sciences and Fisheries with a one year study at UNIS. Her research interests are in fish physiology and ecology in response to climate and anthropogenic changes in the Arctic marine environment. Thesis work will emphasis the long-term effects of dietary petroleum contamination of the reproduction of polar cod.
Libe Aranguren is from Pamplona, Spain. She took her bachelor at the University of Navarra (Pamplona) and was an exchange student at the University of Tromsø during the last year. In Tromsø, she discovered ecotoxicology and liked it very much. She is interested in physiological changes in animals caused by anthropogenic pollution in general and especially in the Arctic. She is now taking her Masters in Arctic animal physiology with her thesis in ecotoxicology. Libe will implement the precision-cut liver slice method on polar cod and study PAH induced changes in mRNA expression of selected genes using this in vitro technique.
Dr James Meador is an environmental toxicologist with the National Oceanic and Atmospheric Administration Fisheries Service in Seattle, Washington, USA. For many years he studied toxicokinetics, bioaccumulation, and the environmental factors that control contaminant bioavailability and toxicity. Over the years this work evolved to include toxic responses as a function of tissue concentrations. In 2007 he organized and chaired a SETAC Pellston workshop that was charged with reviewing the tissue-residue approach for toxicity assessment, which produced a series of articles in the January 2011 issue of the SETAC journal Integrated Environmental Assessment and Management. Over the past 20 years his studies have focused on toxic responses in fish and invertebrates resulting from exposure to polycyclic aromatic hydrocarbons, tributyltin, metals, and other chemicals. More recently he has been studying metabolic disruptors that affect growth and energetics in fish exposed to these chemicals at environmentally relevant concentrations. Jim also has expertise in experimental design, statistical analysis of toxicity experiments, and characterizing the toxic dose in relation to adverse effects.
Dr Ibon Cancio received a Master degree in Biological Electron Miscroscopy in the University of Wales (Abreystwith, UK) and a European doctorate degree in Biology from the University of the Basque Country (UPV/EHU). He is Asscoiate Professor in Cell Biology in his home University; in Bilbao. His experience and training include aquatic toxicology, environmental health assessment, toxicogenomics and Cell Biology of peroxisome proliferation in aquatic organisms. He has published more than 40 indexed research articles and book chapters. His research has involved laboratory studies of the biological effects of metal and organic chemical compounds on marine invertebrates and vertebrates, mainly with the aim of developing pollution effect and exposure biomarkers. As a member of the consolidated reasearch team Cell Biology in Environmental Toxicology in the UPV/EHU, he has been involved in the research effort to understand the biological effects of the Prestige oil spill on the whole coast line of the North Iberian Peninsula. His current research includes the study of the molecular adaptive/maladaptive pathways and of the gene expression patterns diagnostic of specific toxic exposures; applying next generation sequencing and gene expression profiling techniques. His involvement in the POLARISATION project will be mainly concerning the study of peroxisome proliferation and PPAR mediated mechanisms of action of PAHs in the arctic cod.
Dr Perrine Geraudie is a researcher consultant at Akvaplan-niva AS with expertise on fish reproductive physiology and ecotoxicology. Her PhD was focused on endocrine disruptions in roach (Rutilus rutilus) living in polluted areas in Haute-Normandy river (France). She also studied during her post-doctoral position the effects of contaminants on the endocrine system of two crustacean species, the estuarine copepods (Eurytemora affinis), and the shrimp (Machrobrachium faustinum). She has worked in the field to investigate environmental pollution and environmental stressors (parasitism) but she has also conducted in vivo and in vitro studies in roach to study the mechanism of action of xenoestrogens. Her tools and expertise include biochemical analyses (VTG, steroid and ecdysteroid measurements), histology, chemical analysis (HPLC, GC/MS), otolithe reading, and in vitro screening (YES, YAS).
