Originally I was trained in plant biochemistry. My research focuses on links between food quality, health of humans and animals, agricultural methods and plant chemistry.
In particular I am interested in the multidisciplinary aspects, where information from one subject area can be used to improve the understanding of processes and mechanisms in another area.
Presently an important part of my work is to coordinate efforts to increase the impact and application of Food Science and Nutrition at Newcastle University, linking a range of research groups with specialised expertise in food related areas, such as human nutrition, consumer science, clinical research, agronomy and economics. This includes the establishment of the new NU Food facility (see the Research tab).
A particular priority area is human intervention trials to establish cause and effect information regarding the effec of foods and food supplements on human health.
The objectives are to enhance the impact and exploitation of the research and training activities in industry and society and to facilitate the creation and success of multidisciplinary research projects.
Until the end of 2003 I worked as senior scientist in the Danish Institute of Agricultural Sciences, where I initiated several multi-disciplinary research programmes in the areas mentioned above.
Links between food quality, health of humans and animals, agricultural methods and plant chemistry,, in particular:
Research methods to definitively establish cause and effect documentation for foods or food supplements in relation to human health.
Effects of plant secondary metabolites (natural pesticides) on humans, in order to improve the beneficial impact of vegetables and other herbs on human health.
Plant adaptation to low-input conditions regarding product quality and susceptibility to pests and diseases, in order to improve the balance of environmental and economic sustainability in agriculture and horticulture.
The feedback mechanisms (conditioned taste aversion, nutrient sensing) that ensure innate preference for nutritious, non-toxic food, dependent on the present needs, in humans and other animals.
I work in the Food Quality and Health Research Group and am a member of the Human Nutrition Research Centre (www.ncl.ac.uk/hnrc/about/) and the Medicinal Plant Research Group (research.ncl.ac.uk/medplant/).
I am involved in several publicly or commercially funded human intervention studies to investigate a wide range of different potential health outcomes caused by specific foods or diets.
The human trials are carried out using the University's state of the art facilities including the Clinical Research Facility (http://www.ncl.ac.uk/crp/facilities/ncrf/index.htm) and the Clinical Ageing Research Unit (http://www.ncl.ac.uk/caru/). Each intervention trial is done in collaboration with the most relevant and qualified clinical specialists and statisticians to ensure the stringent quality standards as well as efficient and cost-effective delivery.
New facilities specifically designed for food related trials with healthy volunteers are currently being established and expected to open in 2012. They will be part of NU Food, a new facility for food and consumer research, which also will comprise facilities for food production, sensory testing and food-related training activities.
