Roles on external bodies
My specialist teaching area is research, and I enjoy exploring and sharing the creative process of research with others. I am particularly interested in the development of teaching methods for supporting students with statistical analysis, and the use of Excel and SPSS software.
Teaching interests include quantitative research methods, and basic epidemiological statistics such as frequency measures, and the concepts of odds and risk. These are relevant to the understanding of the dietetics literature, and the reporting of key nutritional research such as the Mediterranean diet studies, and the long-running American National Health and Nutrition Examination Surveys. Understanding the statistics behind large, and small, scale studies informs the student's understanding of the evidence behind their practice, and thus is key to becoming and remaining evidence-based practitioners of their profession. I also teach Evidence Based Practice to Year 1 students, including critical analysis skills for reading published research.
Additional roles include the delivery of profession-specific "Dietetics in a Nutshell" lectures. These are one-off sessions aimed at Year 1 students of Health Professions such as Midwifery and Dentistry, which are designed to cover areas of dietetics key to their work, and equip them with the pathways needed to access up-to-date and accurate dietetic information throughout their careers.
PhD Health Studies, thesis title: Non-transferrin-bound iron and protein glycation in type 2 diabetes, explored the effects of high plasma glucose levels on the iron-binding protein transferrin in type 2 diabetes. Laboratory-based work identified fragmentation of transferrin resulting from oxidative damage when exposed to glucose incubation, but subsequent comparison with human samples suggested this effect may have little physiological impact. Further work with human samples found previously unreported links between non-transferrin-bound plasma iron, cholesterol, and haemoglobin, suggesting the increasing fragility of red blood cells in type 2 diabetes.
Other research activity has included working as a Research Dietitian, advising participants on a dietary sodium restriction study investigating blood pressure in overweight, marginally hypertensive adults.
