Professor Chris Elliott

Professor Chris Elliott

Chris is currently Professor of Food Safety and founder of the Institute for Global Food Security at Queen’s University Belfast. He serves as Pro-Vice-Chancellor for the university and is responsible for the Faculty of Medicine, Health and Life Sciences. He has published more 300 peer review articles, many of them relating to the detection and control of agriculture, food and environmental related contaminants. His main research interests are in the development of innovative techniques to provide early warning of toxin threats across complex food supply systems. MORE >

Protecting the integrity of the food supply chain from fraud is also a key research topic and Chris led the independent review of Britain’s food system following the 2013 horsemeat scandal. Over the years Chris has developed a high level network of collaborators across Europe, the United States and Asia. He co-ordinates and participates in multiple European framework research projects.

Professor Johann Six

Professor Johan Six

Professor Six received his PhD in Soil Science in 1998 from Colorado State University. His PhD research was conducted at the Natural Resource Ecology Laboratory (NREL). His research focused on the mechanisms underlying greenhouse gas mitigation by no-tillage practices. Professor Six remained as a Research Scientist at NREL from 1998 until 2002. MORE >

He led and was involved in many projects investigating the effect of land use change and management on greenhouse gas fluxes in agricultural, grassland and forest ecosystems. At UCDavis, Professor Six has further developed this line of research with a focus on the feedbacks between ecosystem management options, global change, and biogeochemical cycling.

More specifically, he studies the complex interactions between soil, plants, soil biota, and the carbon and nitrogen cycles in terrestrial ecosystems, especially agroecosystems. His general approach is to conduct experimental work from the micro- to landscape scale and subsequently integrate it with modeling to interpolate and extrapolate it to the regional and global scale.

His project sites span from small growers’ fields to intensively-farmed production systems to agricultural research stations. We are involved in a suite of international research projects in Africa, Europe, the US, and Central and South America.
