Professor Linda Morgan

Biography

After graduating in Biochemistry from Bristol University, I gained an MSc in Clinical Biochemistry at Surrey University in 1972, as part of a National Health Service training scheme for Laboratory Scientists. I continued within the NHS as a Clinical Biochemist, gaining a PhD in Chemical Pathology in 1977 from London University for my work on the role of the hormone prolactin in the development and management of breast cancer. I joined the staff in the then Department of Biochemistry at Surrey in the late 70’s, as an Experimental Officer, researching on the newly-discovered gastrointestinal hormone, GIP. This work gained national recognition a year later winning the Association of Clinical Biochemists Ames medal for Clinical Research. I remained at Surrey University and in the 1990’s identified Nutrition as a major focus of my work, enabling me to occupy a unique niche in the area of Nutritional Endocrinology, in the UK. I was elected to the Royal College of Pathologists in 1995 on the basis of substantial and sustained research work.
I became Professor of Nutritional Endocrinology in 2004 and I am now a Professor Emeritus.

Research Interests

• The metabolic effects of obesity in relation to CVD and diabetes
• The physiological regulation of appetite, specifically the role of gastrointestinal hormones and exercise in influencing satiety and energy balance.
• Meal timing and postprandial metabolism. The impact of the circadian clock on insulin action, metabolic responses to meals and markers for CVD and diabetes risk.
