Having always had an interest in the bioactive compounds found in plants (phytochemicals), I studied chemistry at the University of Bristol (1992-1994), followed by a PhD in natural product chemistry (1994-1997). This led to research on how phytochemicals impact on disease and I now investigate the complex relationship between diet and human health. My current research aims to establish the metabolic phenotypes defining population groups and with a strong focus on the functional role of the gut microbiota, the effect of dietary change on disorders such as cardiovascular disease, type 2 diabetes and cancer. However, as several challenges impact of our food supply system, my research contributes towards ensuring that our food system is resilient. This includes topics such as maintaining biodiversity, protein provision for the future, revalorisation of food waste and emerging technologies in crop breeding and food formulation. This involves working across a wide range of stakeholders, leadership of food groups in the learned societies and collaboration with industry by chairing International Life Science Institute expert groups, as well as working directly with individual and local companies to help with product development. This requires a truly transdisciplinary approach and with initiatives such as the Leverhulme artists-in-residence scheme, I have explored new ways of working to bring food science to the general public. Through Scottish Government-funded research within SEFARI, we are addressing some of the challenges faced by the Scottish Food and Drink Industry to be able to provide affordable, acceptable and nutritious food by sustainable practices. This collaborative and joined up approach is essential as we move forward to tackle global issues and I also have active research funding to contribute to global food security, exploring high value crops that can be grown in countries such as Malawi and Zimbabwe (see 'Research' tab for further details).
Chair of the ILSI Expert Group ‘Efficacy of intervention in metabolic syndrome’
Objectives of this project are to better understand the role of diet on the defining criteria of metabolic syndrome (i.e. low HDL-cholesterol, high blood pressure, hyperglycemia/insulin resistance, hypertriglyceridaemia and adiposity) and their impact on the risk of cardio-metabolic diseases. This expert group aims to establish an efficacy model for food interventions so that the overall benefits of dietary change can be assessed.
Convener and Trustee of the Board 'AAB Food Systems Group'
Application of biology is integral to the processes and infrastructure involved in feeding our population. As several challenges impact of our food supply system, we have to ensure that it is secure and resilient. This requires a truly transdisciplinary approach across the sciences both on a national and global level. The biological sciences will play a major role, but this will require a strategic and collaborative approach and possibly new and as yet undiscovered ways of working. Within the Food Systems Group, we hope to identify the role in which applied biology underpins our food system and also what can be contributed at an international level. We aim to work with stakeholders across the food supply chain involved in all aspects of food production and to provide a forum for debate and advancement of knowledge of this important scientific topic.
Committee Member 'RSC Food Group'
The aims of the group are to promote the role of chemistry in food and enable transfer and sharing of information and networking between academia and the food industry. This includes analytical, biochemical, chemical, physical, nutritional and toxicological aspects of food and food ingredients and the composition and relationships between structure and functionality throughout the entire food chain in a way to enhance sustainability and food and nutrition security.
Chair of the ILSI Expert Group ‘Nutritional Management of Postprandial Glycaemia’
This project has reviewed the state-of-the-art regarding dietary components and blood glucose.
Associate Editor 'Microbiome'
ILSI Committe 'Low Grade Inflammation - A High Grade Challenge'
This project provided a platform to discuss with key stakeholders the challenges of low-grade inflammation and its importance as a pathological feature of numerous common chronic diseases.
Nutritional-related disorders such as obesity, type 2 diabetes, cardiovascular disease and certain cancers are emerging as a public health crisis. Understanding the balance between diet and human health is vital, if we are to establish evidence for the provision of healthy and sustainable food for all. It is essential that we optimise the nutritional and disease preventative properties of the food we eat, but also that this is achieved by a method that is agriculturally, economically and environmentally viable. Our research is focused on understanding the complexity of the human diet. This includes understanding the availability of compounds from the food matrix, how these are absorbed and transformed in the body and the overall impact on human health. To implement these strategies, we have to work across the food supply chain with food growers and producers, agriculture and environmental scientists, the food industry, health professionals and policy makers.
Harvesting for Health – from the fields
The Food and Drink industry faces many challenges, but one of the main concerns relates to food security. Climate change, increased fuel costs, and changing demographics all add to this uncertainty. However, the industry still needs to be able to provide affordable, acceptable and nutritious food. We are researching the impact of plant breeding on the nutritional content of the crops we eat and exploring the potential of wild and underutilised species as healthy foods.

Harvesting for Health – for the future
As protein supply for the future becomes a critical concern, our research is examining how sustainable plant proteins can contribute to the human diet in terms of nutritional value. We have shown that high protein - low carbohydrate diets are likely to be detrimental to gut health in the longer term and that plant protein has potential ameliorate this risk. The focus of our current work is on identifying sustainable and healthy sources of plant protein to replace or augment traditional sources in the diet. We are also applying novel technologies to reformulate and develop innovative food formulations. This will provide new opportunities for our growers and producers, as well as strategies to enhance nutritional resilience.
Harvesting for Health – from the gut
Emerging evidence suggests that the gut microbiota plays an important role in the development of many diseases including diabetes, cardiovascular disease and cancer. It is becoming widely accepted that the metabolic products formed by gut bacteria directly impact on human health and disease, particularly regarding immune response and inflammation. Through identifying these microbial metabolites, our research hopes to establish the link between microbial diversity and metabolic functionality. This will help elucidate the complex interplay between diet, the gut microbiota and human health.
Gut Health Research Team
As several challenges impact on our food system, it is more important than ever that we understand the complex interplay between diet and health. The human gut and the microbial species that reside within it play a vital role in maintaining our nutritional status and preventing a wide spectrum of lifestyle associated disorders. Our research is defining the role of the gut in delivering food components with a view to improving health through dietary strategies. This will also inform the development of healthy and sustainable foods that will contribute towards nutritional resilience in the food supply chain.

High protein plants play a key role in the development of sustainable agriculture and food production systems. This stakeholder-driven research is allowing us to optimise their agronomy, improve product quality and establish their cultural and economic viability, including the identification of the most promising routes to markets. Human studies will establish the nutritional quality and potential health benefits to allow delivery of sustainable and healthy products with a strong economic advantage for the agri-tech and food industries. We are also exploring additional value from the revalorisation of underutilised agricultural products.

‘Improving Primary Produce’
Domestication may have changed the nutritional composition of the foods we eat and perhaps there are lessons to be learned from wild and underexploited plants. We know that some of these are rich sources of phytochemicals; bioactive molecules beneficial to health. This research is comparing underutilised plant species with more intensively grown contemporary varieties. Human intervention studies will establish the benefits in terms of bioavailability of important nutrients and bioactives. Alongside these studies, the role of growing conditions (location/soil quality) on selected crops will be assessed. This information has potential to inform crop breeding, agricultural practice, food production, as well as consumer choice.

‘Moringa; delivering nutrition and economic value to the people of Malawi’
Without intervention, the provision of adequate food and nutrition in Malawi is an unachievable outcome. Malawi also faces significant logistical challenges of establishing and operating a food and nutrition security programme. To be successful, agriculture will have to change to a more dynamic model that will open up new opportunities for commercialisation. We have partnered with Africa Growing to establish production of a high-protein, micronutrient rich crop (Moringa oleifera), which will be locally grown by smallholder farmers, and processed on-site to supply Malawi's proposed scaled-up nutrition programmes. Contract growing by smallholder farmers ensures the benefits cascade down to the rural population, providing a product ‘grown in Malawi, processed in Malawi for the people of Malawi’. This project will not only contribute towards nutritional security for the poorest and most vulnerable in Malawi, but will deliver recognised additional economic benefits through two commercialisation opportunities: provision of functional plant-based products as increasingly desirable food ingredient for both local and export markets and scientifically-evaluated fair-trade products to enter the growing international market for nutraceuticals.

‘Role of microbial metabolites in cancer prevention and aetiology’
Emerging evidence suggests that the gut microbiota plays an important role in the development of many diseases including diabetes, cardiovascular disease and cancer. Despite tremendous advances in characterizing microbial diversity within the gastrointestinal tract, very little is known about their function and role of even the most dominant bacterial species within the human host. It is becoming widely accepted that the metabolic products formed by gut bacteria directly impact on human health and disease, particularly regarding immune response and inflammation. In most cases, the products of metabolism are uncharacterised and their mechanism of action unknown. Through human interventions with well characterised substrates this project is establishing the link between microbial diversity and metabolic functionality.
