Dr. Nataliia Kulatska is a researcher at the Department of Aquatic Resources at the Swedish University of Agricultural Sciences, Sweden. She has developed a multispecies Gadget model of cod, herring and sprat in the Baltic Sea, to study the effects of both cod and fisheries on herring and sprat including size preferences. Her current projects concentrate on ecosystem analysis, stock assessment and spatial analysis.

Dr. Daniel Howell is a Research Professor at the Institute of Marine Research, Norway. His interests include stock assessment and Management Strategy Evaluations, as well as multispecies modelling and improving the ecological realism in practical management advice.

Dr. Peter J. Wright, MBE, advises on marine conservation and formerly was a principal scientist at the Scottish Government's Marine Laboratory in Aberdeen and UK representative on the ICES Science Committee. His research into fish reproductive biology, recruitment, population structuring and predator-prey interactions has led to 200 publications including many on Atlantic cod. His research informed changes to cod management, including the recent boundary revision of the North Sea and West of Scotland cod stocks.

Dr. Ingibjörg G. Jónsdóttir is a scientist at the Marine and Freshwater Research Institute in Hafnarfjörður, Iceland.
