Christos Palaiokostas


My research is focused on aquaculture breeding programs. Particular emphasis on application of high-throughput sequencing technologies for studying complex traits in aquaculture species.


My current research involves the incorporation of high-throughput sequencing technologies in the ongoing national Swedish breeding programs of Arctic charr and rainbow trout (, aiming at increasing selection accuracies of complex traits.

My prior post in Roslin Institute was under the FISHBOOST project (, aiming at improving genetic resistance of farmed fish against commonly encountered diseases.


I have an MSc in Aquaculture (Stirling University) and an MSc in Sustainable Management of Aquatic Environment. Completed my PhD (2013) in the Institute of Aquaculture (Stirling University, UK) on Analysing sex determination in farmed fish using Next Generation DNA. Additionally, i have worked in as a postdoctoral research fellow in Stirling University and in Roslin Insitute (University of Edinburgh.
