Andreas obtained a M.Sc. in biology at the University of Windsor, Ontario, and worked for several years as an observer in the Alaska commercial fisheries. He then completed a Ph.D. in fishery science at the University of Washington in Seattle. His research there focused on the inter-annual variations of juvenile pollock in the eastern Bering Sea. Andreas returned to Alaska to work at the Fishery Industrial Technology Center in Kodiak, on projects that included evaluating experimental nets for live-capture of fish, and studying the relationships between Steller sea lions and their prey distributions. More recently he was employed at Virginia Tech University to investigate abundance estimates of Lake Erie walleye, Atlantic coast weakfish, and seabird mortalities in longline fisheries. Since joining the Falkland Islands Fisheries Department he has been involved in the stock assessment of Loligo squid and the analyses of survey data.
