Biography
Professor Umpleby obtained her first degree in Biochemistry from the University of Cambridge and her PhD from the University of London. She held various academic appointments between 1982 and 2005 at UMDS subsequently Kings College London. She was appointed Professor of Human Metabolism at Surrey University in 2005. She is a member of the Medical Research Council College of Experts and is Associate Editor of the journal Growth hormone and IGF Research. In 2005 her research group was awarded the International Award for Excellence in Published Clinical Research in the Journal of Clinical Endocrinology & Metabolism for their paper describing the role of IGF-I in the control of metabolism in type 1 diabetes.
She is an international expert on the use of stable isotopes for the study of human metabolism. Her research aims to understand the mechanisms that lead to insulin resistance and abnormalities in fatty acid and lipoprotein metabolism in diabetes, obesity, metabolic syndrome and non alcoholic fatty liver disease. She works in partnership with researchers in the division of Nutrition and with clinicians at the Royal Surrey County Hospital. Her research group also works closely with the Pharmaceutical Industry in the investigation of new treatments.
Her expertise has led to collaborations worldwide and over 90 peer reviewed publications. She has received over £3.5m in research funding in the last 10 years from the BBSRC, Wellcome Trust, BHF, Heart Research UK, Diabetes UK, European Foundation for the Study of Diabetes and the Pharmaceutical industry.
Research Interests
The research strategy of the department focuses on:
• understanding the underlying mechanisms that lead to metabolic abnormalities in diabetes, obesity, metabolic syndrome and non alcoholic fatty liver disease.
• the translation of this understanding into effective treatment.
We are uniquely able to conduct this research strategy due to our expertise in the use of stable isotope techniques, and their measurement by mass spectrometry which can determine in vivo the rates of synthesis, disposal and conversion of metabolites in the body.
• We offer research training leading to the postgraduate degrees of MPhil, PhD or MD.

Abstract
Context:High plasma triglycerides (TG) have been shown to be independent and better predictors of cardiovascular disease than low-density lipoprotein (LDL) cholesterol in women. This may be due to gender differences in very-low-density lipoprotein 1 (VLDL(1))- and VLDL(2)-TG and fatty acid kinetics.Objective:Our objective was to investigate whether there are differences in VLDL(1)- and VLDL(2)-TG and fatty acid kinetics in obese men and postmenopausal women, a high risk group for cardiovascular disease.Research Design and Methods:Stable isotopes techniques were used to measure fasting palmitate rate of appearance, metabolic clearance rate, oxidation rate, and nonoxidative disposal rate, VLDL(1)-TG and VLDL(2)-TG fractional catabolic rate (FCR) and production rate (PR). Whole-body fat distribution was measured by magnetic resonance imaging.Participants:Participants included 10 postmenopausal obese women and eight obese men matched for age, body mass index, and fasting plasma TG.Results:The women had lower visceral fat and higher sc fat than the men (P < 0.001 and P < 0.002). Palmitate rate of appearance, metabolic clearance rate, nonoxidative disposal rate, and oxidation rate corrected for resting energy expenditure were greater in the women than the men (all P < 0.03). VLDL(2)-TG PR corrected for fat-free mass was higher in the women (P < 0.001). VLDL(2)-TG and VLDL(2)-cholesterol pools were higher in the women (P < 0.001 and P < 0.008). VLDL(1)-TG FCR and PR and VLDL(2)-TG FCR were not different between genders.Conclusion:Fatty acid and VLDL(2)-TG flux is higher in postmenopausal obese women than in obese men matched for fasting plasma TG levels.

Abstract
Insulin detemir lacks the usual propensity for insulin to cause weight gain. We investigated whether this effect was a result of reduced energy intake and/or increased energy expenditure.
