Meredith Peddie has a BPhEd (Hons) in Sports Science, a BSc and MSc in Nutrition, and graduated with her PhD from the University of Otago in 2012. Between 2012 and 2020 Meredith worked in the Department in research positions funded by the National Heart Foundation of New Zealand. She joined the Department permanently as a Senior Lecture in February 2020. Meredith's main area of research focuses on the postprandial metabolic effects of interrupting sitting time with short bouts of physical activity, but she is also interested in how moving more and sitting less impacts health in a broader sense. Meredith's other research interests include the impact of nutrition, sedentary behaviour and physical activity on cardiometabolic risk.

Meredith welcomes post-graduate students with an interested in sedentary behaviour, physical activity and nutrition.
