Dr Silvia Gratz

I am a human nutritionist and food toxicologist and my research interests focus on diet, intestinal toxicity and the role of gut microbiota. My research looks at important food contaminants and I aim to assess human exposure and identify potential risks to human health. As these food contaminants derive from primary agricultural production I also work closely with producers as well as Food Standards Scotland to understand routes of contamination and identify strategies to minimize risk and produce safe and healthy food.

Professor Alexandra Johnstone

I am a nutrition scientist at The Rowett Institute with an interest in mechanisms of human appetite control and energy balance. The UK is in the midst of an obesity epidemic, arising from low activity and easy availability of energy-rich foods. My research strategy has been to investigate the effect of diet on appetite control and energy balance. This has been driven by developing a strategy to systematically examine the effect of amount, type and timing of nutrient intake on energy balance. My research funded by EU and UKRI grant awards, have explored the role of diet on health.
