George taught computer science and engineering at UW SET. He retired from teaching but continues active research and writing in the field of systems science and engineering. His major research interest is in developing a general systems analysis approach, particularly for the human social system as a subsystem of the whole Earth system with the objective of deciphering what a more viable social system would look like.
Delia MacNamara Past-President
Delia Pembrey MacNamara lives in Canberra, Australia, and is the current President of the International Society for the Systems Sciences (ISSS).
Delia works for the Australian Federal Government in the artificial intelligence, automation and digital transformation applying cybernetics and systems sciences to enterprise and whole-of-government ethics, governance and strategy.  
Delia’s core research area is the ontology of boundary from an embodied cognition perspective with a passion for applying her research to care, compassion, aged care reform and reaching for the impossible (which is always possible with others).
Delia is undertaking a PhD researching A Critical Analysis of the development of the Boundary Triage and its Objects as a Critical Systemic Leadership Development tool for the Networked World. 
Roelien Goede President-elect Working as programmer, I soon realized that people do not know what they want, or that is how I perceived it from my functionalist training. Later I learned that multiple perspectives enriches one's understanding and that a model is only one version of  the proposed system. I was introduced to systems thinking by the book: "Computers in Context" By Dahlbom and Mathiassen and immediately understood how my thinking was post-functionalistic.   I worked for 10 years in a group of systems thinkers in the Netherlands and then I was granted the opportunity to attend the very last edition of the Lugano Summer school presented by Peter Checkland and Werner Ulrich in 2012. Ulrich's message of "Giving a voice to the affected" was something I could relate to being from South Africa - a country known for "not listening to the affected".  I also learned that in the corporate world there are involved and affected parties and I'm striving to find technical computer science solutions to design problems that are inherently flexible enough to support different perspectives. I met Gerald Midgley in the group of systems thinkers in the Netherlands and he invited me to ISSS in 2014 in Washington when he was President of the ISSS. 2021-2023

Gary Smith VP Systems Practice
Based in the UK. Is a senior expert systems engineer at Airbus, an systems of systems architect/technical manager and is engaged on enterprise transformational programmes.
He is an INCOSE ESEP and helped to establish their PM-SE Integration Working Group. He is also the senior editor for the SEBOK - section 2: System Foundations. He is our INCOSE liason.
Has also studied and published a series of papers attempting to understand biosystem complexity and the underlying patterns in disease conditions. "Cancer, Inflammation and the AT1 and AT2 receptors", "Angiotensin and Systems Thinking - Wrapping your mind around the big picture", Architectural Parallels between engineered and biological defence and Security". Most recently he was a coauthor of a paper in frontiers of medicine - "The Lung, the Heart, the Novel Coronavirus, and the Renin-Angiotensin System; The Need for Clinical Trials"
With Brigitte Daniel Allegro they published "Exploring the branches of the system landscape" - the branches being the attitudes of the systems thinker, and the roots being the system concepts that they think about.
Has co-lead two IFSR conversations "Unity in diversity" and "What is system science?". Is currently helping to establish an architecture for system science, to facilitate a shared orientation to establish a learning system for our knowledge about systems and knowledge about how we engage with systems.

Howard Silverman VP Conferences
Howard Silverman teaches applied systems thinking and strategy+foresight in the Collaborative Design MFA / Design Systems MA programs, Pacific Northwest College of Art at Willamette University. Formerly, he was senior writer and analyst with the nonprofit Ecotrust, working at the intersection of social-ecological relationships in food, fisheries, forestry, green building, and so on. 
Javier Calvo-Amodia VP Research and Publications
Javier Calvo-Amodio, Ph.D. is an associate professor of Industrial and Manufacturing Engineering at Oregon State University, where he directs the Change and Reliable Systems Engineering and Management Research Group (CaRSEM). He received his Ph.D. in Systems and Engineering Management from Texas Tech University, his MS in Business Management from the University of Hull in the United Kingdom, and his B.S. in Industrial and Systems Engineering from Tecnológico de Monterrey in Mexico.
Dr. Javier Calvo-Amodio's research focus is on developing fundamental understanding of how to integrate systems science into industrial and systems engineering research and practice to enable better engineering of continuous process improvement organizational cultures. His research group, Change and Reliable Systems Engineering and Management (CaRSEM), works with Oregon’s industry, state agencies, the National Science Foundation, and other professional societies to determine systemic principles that guide the design, assimilation, and management of the systems engineering process, as well as continuous process improvement approaches such as Lean and Six Sigma.
