Personal profile


I work as a senior scientist at the Centre for Environment, Fisheries & Aquaculture Science (Cefas), Lowestoft, and am linked with ENV as Honorary Lecturer with roles as PhD and MSc supervisor. At Cefas I lead a portfolio of research in marine science, with special focus on the long-term changes in fish populations and fish distributions, as well as the drivers behind these, such as climate change, fishing pressure, habitat modification, and changing predator-prey interactions. My work also encompasses the dynamics of the fishing fleets exploiting these, as well as the top predators (such as marine mammals) that are often dependent on the same, shared, marine living resources. 

One of my core areas lies in the emerging field of marine historical ecology, which aims at understanding the past of the marine environment over time-spans stretching many decades to even centuries – and placing insights from historical data in a current policy context. I am a member of the Oceans Past Initiative (OPI) and Co-Chair of the Working Group on the History of Fish and Fisheries of the International Council for Exploration of the Sea (ICES, housed in Copenhagen). 

Almost any aspect of the marine environment interests me (and I also follow developments in the terrestrial realm), and my study species have, over the years, come from diverse branches of the animal kingdom (with MSc studies on a new subspecies of snail and tropical butterflies, and a PhD on sub-Antarctic elephant seals). 

I have a twitter account @EngelhardGeorg – all views are my own and not those of Cefas or the university.
