Dr Hollington has worked in Bangor University's School of Natural Sciences and its predecessors for almost 30 years. After a degree in Agriculture, and a PhD in Grassland Agronomy, both in Aberystwyth, he worked at the old Welsh Plant Breeding Station, where his focus was on grassland and sustainable production.
After moving North in 1989, Dr Hollington was heavily involved inconsultancy, research and teaching on more global aspects of agriculture, environment and food production. Since 2012, he has developed and led the MSc in Food Security in the Changing Environment at Bangor University, largely focused on the challenges facing sustainable food production in the light of global change and rapid advances in science and technology, and on what drives consumer and government responses and attitudes to these changes. It also looks at the conflicts between different sectors and stakeholders, and how they might be resolved.
Dr Hollington lives in Beaumaris on Anglesey, which has fostered other interests in coastal and marine ecosystems, and he also sits on the Welsh Marine Advisory and Action Group.
