Ailbhe Macken is a researcher at NIVA in the section for Marine Pollution. She has over 16 years of experience working and researching in the area of ecotoxicology and environmental science. Her areas of expertise and experience include marine biological effects monitoring and the application of effects directed analysis and toxicity identification evaluation in marine waters and sediment, development and the use of in vivo and in vitro bioassays, nano and regulatory ecotoxicology (GLP) and risk assessment. She has experience in all aspects of invertebrate and aquatic regulatory ecotoxicity testing including hazard assessment of environmental mixtures and single substances for product registration. She has experience in the ecotoxicological testing of “difficult” substances (e.g. sparingly soluble, volatile, and unstable) and has a sound working knowledge of the regulatory legislation (e.g. REACH, GHS and EMEA) and in marine and environmental directives and legislation (e.g. WFD, EU Marine Strategy Directive). Since 2015 Ailbhe has been the GLP Deputy Manager in addition to her role as Study Director and test personnel. She is the lead for the Working Group on Ecotoxicology in the Norman Network group on the Fate and Impact of ENMs in the aquatic environment (sludge, soil, sediment, leachates), and has participated as a member of the EC expert advisory group on endocrine disruptors. In addition she is a Norwegian Representative on the OECD Validation Management Group for Ecotoxicology. Dr Macken is actively involved in several EU and national funded projects, (e.g. NFR Nano2021: Nanowaste - NIVA project lead), and is involved in the supervision of Masters, PhD students and PostDocs. Ailbhe is widely published in the field of marine science and ecotoxicology and has been an invited speaker at many In
