David has worked in clinical research for over 35 years; his work primarily relates to stroke and other chronically disabling neurological disorders, as well as clinical and public policy analysis. More recently, he has applied simulation modeling to clarify the challenges of a rapidly aging population, including future prevalence of disability and the impact of education the trajectory of prevalence, understanding the role of different forms of long-term care services in alleviating caregiver burden, and estimating health care manpower requirements under alternative models of care.

David N. Ford
Virginia Tech
David N. Ford, Ph.D., P.E. is the Vecellio Professor of Construction Engineering and Management at Virginia Tech. His current research focuses on planning for and managing natural disasters. Prior to joining Virginia Tech, David was Professor at the Texas A&M University. He was a Research Associate Professor of Acquisition in the Graduate School of Business and Public Policy at the US Naval Postgraduate School for a dozen years, where he researched military acquisition using system dynamics and knowledge value added analysis. His background includes a faculty position at the University of Bergen, Norway. For over fourteen years he designed and managed the development of constructed facilities in industry and government. He received his Ph.D. from MIT and his Masters and Bachelors degrees from Tulane University. He has served as the President of the System Dynamic Society.

Douglas McKelvie and Eric Wolstenholme
Symmetric Scenarios
Douglas uses simulation to support strategic planning in health and social services. He has built models for a range of organisations across the UK, including government departments, National Health Service bodies, and local authorities. Where possible, he uses group model building, taking a ‘whole system’ view of the complex issues found in health and social care integration, where services span agency and functional boundaries, and also in children’s services. Douglas is a past President of both the UK Chapter and the Health Policy SIG of the SDS and has written about the use of simulation in health, social care, and related human services. He lives in Edinburgh and works across the UK (sometimes beyond).
Eric worked in Operational Research for British Coal and was Head of the first System Dynamics Research Group in the UK at Bradford University Business School. He subsequently held full Professorial posts at Stirling, Leeds Beckett and London South Bank Universities and helped establish two management consultancies in System Dynamics – Cognitus and Symmetric. He was a founding member of the System Dynamics Society, its fourth President and the Founding Editor of the System Dynamics Review. He has also been President of the UK Chapter of the SDS from which he received an Outstanding Contribution award and ISDC 1994 Program Chair. In 2004 received the Jay Wright Forrester Award for his work on generic systems archetypes. Eric holds a Bachelor of Science degree and Doctorate in Engineering from Nottingham University UK and a Master’s degree in Operational Research from Brunel University UK.

Enzo Bivona
University of Palermo
Enzo is Associate Professor in Business Management at the University of Palermo. He has a PhD in Business Administration and a Master Phil. in System Dynamics from Bergen University in Norway. His work focuses on performance management and policy design primarily in Small and Medium Enterprises (SMEs). He uses the System Dynamics methodology to build simulation models to support decision makers to test and implement sustainable long-term strategies. He is author of two books on how to design and introduce management control systems in organizations to influence the management and governance of such firms as well as, ultimately, their performance.

Hazhir Rahmandad
Massachusetts Institute of Technology
Hazhir Rahmandad is the Schussel Family Professor of Management and Associate Professor of System Dynamics at the MIT Sloan School of Management. Hazhir’s research applies dynamic modeling to problems spanning strategy and healthcare. His organizational work focuses on understanding challenges to learning in dynamic tasks and their implications for strategies adopted by firms. His health research uses modeling to understand various systemic problems from obesity to depression and COVID-19 pandemic. His methodological work contributes to parameter estimation methods for dynamic models and aggregation of prior statistical findings.

Ihi Heke, Paora Te Hurihanganui, and Hemi Taitin
Dr Ihi Heke is the lead author of Systems Science and Indigenous Systems: Native Contributions to Global Obesity Prevention (funded by Johns Hopkins), an honorary research fellow in epidemiology and biostatistics to the University of Auckland and contracted consultant to Google X on unconscious bias.
Paora Te Hurihanganui is an indigenous health promoter leading a staff of 50 as their current chief executive officer.
Hemi Taitin is senior leadership in an indigenous school aimed at using systems science (also known as whakapapa) to redress a colonised curriculum. In addition, Hemi is the current national lead for the Māori Weaponry school known as Tū Tau.

John Hayward
University of South Wales
John Hayward is a visiting fellow in mathematics based at the University of South Wales. Before retirement, he was a lecturer at the university, teaching specialist courses in system dynamics, mathematical modelling and agent-based methods. He was awarded his BSc in astrophysics and PhD in applied mathematics from the University of London. John’s research is in the growth of religious and political movements, historical modelling and integrating mathematical approaches into system dynamics practice.

Juliette N. Rooney-Varga
University of Massachusetts Lowell, Climate Change Initiative
Juliette is a Professor in Environmental Sciences, director of the Climate Change Initiative, and co-director of the Rist Institute for Sustainability and Energy at the University of Massachusetts Lowell. Her research focuses on the nexus of climate change and sustainability science and decision support. She develops and analyzes the impact of dynamic modeling and interactive simulations that enable people to learn for themselves about the climate and energy systems. These simulations bring current climate change and energy science to students, citizens, and policymakers at all levels and have been shown to motivate science-informed action.

Mike Severson
Idaho National Laboratory
Mike is a systems researcher at the Idaho National Laboratory with experience in system dynamics modeling, supply chain assessments, and techno-economic analyses. During his tenure at the Idaho National Laboratory, Mike has authored and co-authored numerous academic publications and United States government reports. Prior to his time in research, Mike worked in the aerospace industry gaining experience in a multitude of areas such as materials science, stress analysis, and mechanical design.

Mohammad Jalali and Erin Stringfellow
