UA is one of the leading universities in Belgium with modern and up-to-date educational and research facilities. UA is ranked 13th in top young universities in the QS world university. Zebrafishlab was founded in 2010 as a joint academic laboratory of UA with members from the Veterinary Sciences and Biology departments. The research of Zebrafishlab focuses on the use of zebrafish (embryos) in ecotoxicology and food safety. Zebrafishlab uses an AOP-based strategy to develop alternative testing approaches using zebrafish embryos and in vitro/in chemico methods. Endocrine disruption has always been one of the main research lines and during recent years thyroid disruption has become a particular focus area. Together with collaborators from the US Environmental Protection Agency (EPA), Zebrafishlab recently built an AOP network for thyroid disruption in fish (OECD AOP project 1.35) and integrated this network with existing information in mammals and amphibians resulting in a cross-class AOP network which will provide the starting point for the ERGO project.
