The IBTN Executive Committee currently serves at the helm of the IBTN. Its members are all experts in their own right in various subfields of behavioural science. They contribute actively to the IBTN’s current projects, including the organization of the annual conference and the new SPOR initiative through which the IBTN Summer School is offered.

The founding members of the IBTN were drawn from a variety of areas and countries. These international experts have many years of experience in developing and delivering behavioural trials and a number of them have been involved in some of the largest trials in our field. They have pulled together this expertise to create the IBTN and through this work hope to improve the quality and quantity of behavioural interventions and trials.

Susan Michie, PhD

Dr. Susan Michie is Professor of Health Psychology at University College London (UCL) and Director of its Centre for Behaviour Change and its Health Psychology Research Group. She is Principal Investigator of the Human Behaviour-Change Project. She is a chartered clinical and health psychologist, whose research focuses on behaviour change in relation to health: how to understand it theoretically and apply theory to intervention development and evaluation, and to evidence synthesis. This is conducted in the domains of risky and preventive behaviours amongst the general population (e.g. smoking, alcohol use, preparing for pandemic flu), managing illness (e.g. medication adherence), and professional practice and implementation (e.g. hand-hygiene amongst hospital staff). Her work includes developing and evaluating digital interventions and investigating the fidelity of delivery of interventions. Her research develops methods to advance the study of behaviour change, including frameworks such as the Behaviour Change Wheel and the Theoretical Domains Framework, and specifying intervention content using taxonomies of behaviour change techniques (BCT Taxonomy v1). Two relevant books she has authored are The Behaviour Change Wheel Guide to Designing Interventions and The ABC of Behaviour Change Theories.


Paul Montgomery, PhD

Dr. Paul Montgomery is Professor of Social Interventions at the University of Birmingham (UK) and leads on the development of the CONSORT-SPI, a reporting guideline for randomised trials of complex psychological and social interventions. His research focuses on improving our understanding of what interventions are effective in tackling complex psychological, social, and health problems and GRADE- CI a tool to assess a body of evidence for systematic reviews. His academic work spans a range of issues, from chronic sleep problems to HIV/AIDS, and integrates the use of several high-quality methodological approaches, many of which have not been traditionally applied in the social sciences. This work falls under three broad categories: (1) Methodology of Psycho-Social Intervention, (2) Nutrition, and (3) Behavioural Interventions. This work has been widely published and he has received funding from multiple sources. A social worker by training, Paul maintains a clinical practice on top of his academic work, where he specialises in Brief Intervention and Cognitive Behavioural techniques for depression, anxiety and insomnia, and treats both adults and adolescents.

Lynda Powell, PhD

Dr. Lynda Powell is the Charles J. and Margaret Roberts Professor of Preventive Medicine, Medicine (Cardiology), Behavioral Sciences, and Pharmacology and Chairman, Department of Preventive Medicine and Rush University Medical Center. Her research specializes in the behavioural treatment development and behavioural randomized clinical trials to promote cardiometabolic health. Dr. Powell has been the Principal Investigator of six major randomized behavioural clinical trials and a founding faculty member and former Co-Director of the NIH-OBSSR Summer Institute on Behavioral Clinical trials, now in its seventeenth year.  Dr. Powell was a Principal Investigator of the NIH-funded ORBIT network which included seven sites all of whom were in the process of developing behavioural interventions for obesity and created the ORBIT model for behavioural treatment development from the experiences of the ORBIT.

She has been PI of a number of clinical trials fostering smoking cessation and reduction of weight gain via pharmacological and behavioral treatments. A NIDA-funded effectiveness trial that delivers her intervention using the nationwide tobacco telephone quit lines is currently ongoing. She was also founding editor and editor-in-chief of Translational Behavioral Medicine: Practice, Policy, Research. She chairs the NIH PRDP standing study section, previously chaired the American Psychological Association’s Board of Scientific Affairs and the American Heart Association’s Health Behavior Change Committee. She is PI of several trials using technology-supported interventions to foster change in multiple diet and activity behaviors or weight loss. Her current trials implement novel research designs adapted from engineering science to optimize and increase the efficiency of behavioral intervention development.  Her NIH-funded on-line learning modules on evidence-based practice ( and on team science (  are freely accessible online.



Molly Byrne, PhD

Dr. Molly Byrne is a Professor of Health Psychology at the National University of Ireland, Galway. In 2014 she was awarded a Health Research Board (HRB, Ireland) Research Leadership Award (2014-2019) to establish and direct the Health Behaviour Change Research Group (HBCRG).
