Dr Luke Gemming is the Director of Teaching for the School of Health Sciences and a fellow of the Higher Education Academy. Luke is an accredited practising dietitian (Dietitians Australia). Luke completed his dietetic training at the University of Wollongong in 2009 before commencing his PhD at the National Institute for Health Innovation (NIHI), University of Auckland. Dr Luke Gemming's work focuses on improving the accuracy, reliability, and application of dietary assessment methods. His research is characterised by the integration of emerging technologies—particularly image-based and sensor-driven tools—to better capture real-world eating behaviours and address longstanding limitations in self-reported dietary data. 

A central theme of Gemming’s publications is dietary misreporting and measurement error. His earlier work demonstrated the prevalence of under-reporting in nutrition surveys and identified the specific foods and meals most commonly omitted, contributing to international understanding of bias in dietary epidemiology. Building on this, he has led and collaborated on studies using wearable cameras and mobile technologies to enhance dietary recall accuracy, including validation studies showing improved estimation of energy intake. 

More recent publications highlight his involvement in large-scale, technology-enabled nutrition studies. Notably, the studies examining how social context and food preparation location influence dietary quality among adults, demonstrating the potential of passive image capture to generate detailed behavioural insights. His work also extends to systematic reviews of dietary assessment methods in clinical settings, including hospital food intake monitoring and patient satisfaction with food services. 

Gemming’s research spans public health nutrition, clinical nutrition, and sports nutrition, including studies on energy balance, nutritional knowledge, and the application of digital tools in nutrition care. His publication record includes journal articles, conference papers, and book chapters, reflecting a sustained contribution to advancing methodological innovation in nutrition science. 

Luke’s teaching journey began in 2008 as a tutor and has been lecturing within various nutrition, sports nutrition, public health nutrition and food service courses since 2011. Luke was previously employed as a lecturer/senior lecturer within Nutrition and Dietetics programs at the University of Auckland and University of Sydney.
