Rate My Professor Megan Rollo

Dr. Megan Rollo serves as Honorary Senior Lecturer in the School of Health Sciences (Nutrition and Dietetics) within the Faculty of Health and Medicine at the University of Newcastle, Australia. She earned her PhD in Nutrition and Dietetics from the Queensland University of Technology, along with a Bachelor of Health Science in Nutrition and Dietetics and a Bachelor of Applied Science from the same university. As an Accredited Practising Dietitian, Rollo has dedicated her career to advancing the field of nutritional science through innovative research on dietary assessment methodologies.

Her primary research specializations include the development and validation of technology-based tools for precise dietary intake evaluation, such as smartphone image-based assessments, voice-image-sensor technologies (VISIDA), and personalized nutrition interventions. Key projects under her leadership or significant contribution encompass the VISIDA initiative to enhance nutrition assessment accuracy, the Diet Bytes and Baby Bumps study on pregnancy dietary patterns in Newcastle women and Indigenous communities, Nutrition For You for young adults' healthy eating, investigations into food addiction mechanisms, dietary influences on migraines, and gender-tailored diabetes prevention programs. Rollo has collaborated extensively within the Priority Research Centre for Physical Activity and Nutrition, focusing on behavioral interventions to optimize dietary intakes during critical life stages like pregnancy and early childhood in Indigenous populations. Her scholarly contributions feature prominent publications including 'Accuracy of energy and nutrient intake estimation versus observed intake using an image-voice dietary assessment tool: a randomized controlled laboratory study' (2024, American Journal of Clinical Nutrition), 'A Systematic Review of Technology-Based Dietary Intake Assessment Tools for Adults: Current Status, Challenges, and Next Steps' (2017, Nutrients), 'Impact on dietary intake of a self-directed, gender-tailored diabetes prevention program: a secondary analysis of a randomized controlled trial' (2017, World Journal of Diabetes), and 'Effectiveness of interventions to optimise dietary intakes in the first 1000 days of life in Indigenous children: a systematic review' (2021, Public Health Nutrition). In recognition of her impactful work, she received the inaugural Chester Goodsell Memorial Award in 2022. Rollo's advancements have profoundly influenced nutritional epidemiology, clinical practice, and public health by enabling scalable, accurate dietary data collection.
