Dr Hartl is an Associate Professor of Marine Biology, specializing in Marine Ecotoxicology in the Centre for Marine Biodiversity & Biotechnology (CMBB), Institute of Life and Earth Sciences, at Heriot-Watt University. He is also Director of the CMBB and Director of Studies for the MSc cluster in Marine, Environment and Climate Change (s Dr Hartl represents the Marine Alliance for Science & technology, Scotland (MASTS) on the Scottish Government’s Marine Litter Advisory Group Steering Committee and leads the MASTS Stressors Forum ( He received an MSc from the University of Vienna (1996) in Biology (Zoology/Marine Ecology) and a PhD from the University of Southampton (2000). Following a Postdoctoral Fellowship at University College Cork (2001-2006), he took up a position as Lecturer in the School of Life Sciences at Heriot-Watt University, Edinburgh. He was president of the Physiology Section of the American Fisheries Society (2010-2012) and served on the Environmental Pollution Review Panel for FORMAS (2011-2014).
