David is working on understanding large-scale systemic risk and supporting policy and sociatial responses. Up until the beginning of 2020, he was director of Risk and Response at the Geneva Global Initiative. Here his work was aimed at encouraging and supporting large-scale preparedness and contingency planning for intensifying large-scale systemic risks. This included engagement with governments, contingency agencies, militaries, intergovernmental and civil society organisations. He is a fellow of The Institute for Integrated Economic Research-Australia.

He is a systems thinker, physicist and human systems ecologist, interested in the challenges to our societies arising from the transformation of risk. This fits into his broader interests into the evolution, stability, and collapse of complex socio-economic systems. He is an advocate for a re-appraisal of risk and the need for societal resilience, instability preparedness, and catastrophic shock planning.

David draws upon ideas from fields such as ecology, complexity and systems science to shed light on emergent risks, vulnerabilities and uncertainties. He has written influential studies on the financial and socio-economic implications of a peak in global oil production; the propagation of catastrophic financial and monetary shocks through trade networks and critical infrastructures. He has also worked on pandemic shocks and integrated approaches to systemic risk.

He has given briefings, lectures and delivered workshops world-wide to governmental and non-governmental organisations, critical institutions, critical infrastructure companies and the general public. He taught a masters course Human Systems Ecology & Systemic Risk at Masaryk University in the Czech Republic. David was a ministerial appointment to the council of Comhar, Ireland’s sustainable development commission. He spent a number of years on the executive committee of Feasta, The Foundation for the Economics of Sustainability – a think-tank. David also made a significant contribution to the Foresight Analysis Nexus.

David studied physics at Trinity College Dublin, the University of London and the Tyndall National Institute.
