About this project

Join an innovative research project at the forefront of digital health! We are seeking a motivated PhD student to develop and evaluate a cutting-edge AI-powered lifestyle intervention aimed at promoting physical activity and healthy eating. This project offers a unique opportunity to work with leading experts in public health, nutrition, and digital health technology at the University of South Australia’s Alliance for Research in Exercise, Nutrition and Activity (ARENA) Research Centre.


As a PhD candidate, you will benefit from:

  • Hands-on experience in developing and evaluating a state-of-the-art AI health coach.
  • Interdisciplinary collaboration with health professionals, government agencies, and community groups.
  • Opportunities to publish your work in high-impact journals and present at international conferences.
  • A supportive research environment with comprehensive mentorship and professional development.


If you are passionate about digital health and eager to make a real-world impact, apply now to join our team and contribute to pioneering research that aims to improve public health outcomes.


What you’ll do


The primary objective of this project is to develop and evaluate a cost-effective, scalable lifestyle intervention that leverages artificial intelligence (AI) to promote physical activity and dietary changes. The key question this project seeks to answer is whether an AI-powered lifestyle intervention, delivered as a hybrid of human and AI health coaches, can achieve similar health outcomes to traditional one-on-one telephone health coaching but in a more cost-efficient manner. The challenge lies in maintaining the effectiveness of personalized support while reducing costs and expanding accessibility. The project will employ a Type 2 hybrid implementation-effectiveness randomized controlled trial (RCT) to rigorously evaluate the AI-powered intervention. This methodology will assess both the effectiveness and scalability of the intervention, with a focus on high-risk and underserved populations. If successful, the intervention model can be adopted by health services across Australia, demonstrating the potential of digital technology to complement human support and enhance public health efforts.


The successful applicant will undertake a variety of activities throughout their PhD project. They will have a leading role in running co-design activities with end-users, which will be essential in informing the development of the AI-powered lifestyle intervention software. Additionally, the applicant will gain comprehensive experience in all aspects of conducting the randomised controlled trial (RCT), including participant recruitment, data collection, and analysis.


There is the possibility of travel to regional South Australia locations to engage with participants and stakeholders, although this is not a requirement. Travel costs will be covered by the supervisors. This role offers a unique opportunity to develop expertise in digital health intervention design, implementation, and evaluation, while working closely with a diverse and multidisciplinary team.
 

Where you’ll be based
 

The project is conducted within the research environment of the Alliance for Research in Exercise, Nutrition and Activity (ARENA). ARENA focuses on multidisciplinary approaches to improving health through physical activity, nutrition, and innovative interventions, making it an ideal setting for this project. This project complements existing research themes at ARENA by leveraging digital health technologies to promote lifestyle changes and improve public health outcomes.


ARENA's areas of research strength, particularly in physical activity promotion, health behaviour change, and digital health interventions, provide a strong foundation for this project. The project is being conducted in close collaboration with Preventive Health SA, and will be guided by a steering group with representatives from government agencies, non-government organizations, and community groups, underscores the project's commitment to end-user engagement and its potential for significant impact. By integrating advanced AI technology with existing health services, the project aims to deliver scalable and effective lifestyle interventions, contributing to the broader goal of improving public health and reducing healthcare costs.


You will be part of a collaborative research team, supervised by Professor Carol Maher, Associate Professor Karen Murphy, and Dr. Ben Singh, each bringing extensive expertise and a strong track record in their respective fields of digital health, dietetics and exercise physiology. This PhD is offered as part of a nationally funded project, ensuring it is very well resourced in terms of developing cutting-edge software and conducting a large, high-quality randomised controlled trial.
