the CoastalME modelling environment for simulating decadal to centennial morphological changes. He led the Committee on Climate Change's 2018 report Managing the coast in a changing climate. Climate Change: Hall's research on adaptation to climate change has focused on climate change risk assessment and decision-making under uncertainty. He was a contributing author to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change which won a Nobel Peace Prize. He was an advisor to the Stern Review on the Economics of Climate Change and led the infrastructure background paper for the Global Commission on Adaptation. Between 2009 and 2019, Hall was a member of the UK Adaptation Committee which is part of the Independent Climate Change Committee established by the 2008 UK Climate Change Act. He is chair of the Steering Group of the £18.7m UKRI Climate Resilience Programme and served on the Governance Board and the Peer Review Panel for he UK's national climate projections, UKCP 18. Infrastructure Systems: Jim Hall founded the UK Infrastructure Transitions Research Consortium which received two research Programme Grants from the Engineering and Physical Science Research Council. Hall led the development of the National Infrastructure Systems Model (NISMOD) which simulates the behaviour and interactions between energy, transport, digital, water and waste systems. NISMOD was used for the National Needs Assessment led by Sir John Armitt and for the UK's first National Infrastructure Assessment. Hall now chairs the £8 million Data and Analytics Facility for National Infrastructure (DAFNI) at the Rutherford Appleton Laboratory. His book The Future of National Infrastructure sets out the challenges of sustainable infrastructure in the 21st Century and provides a template for assessing long-term policy, planning and investments. NISMOD has been taken up by the UN Office for Project Services (UNOPS) in pursuit of the Sustainable Development Goals and has been used to inform infrastructure planning in Curaçao, St Lucia and Ghana. Hall developed several methods for analysing risks to infrastructure networks and prioritising actions to enhance network resilience. The work was used as part of the National Infrastructure Commission's 2020 study of infrastructure resilience. The work has twice been recognised with the award of the Lloyd's Science Prize and it has been applied to the analysis of infrastructure network resilience in Tanzania, Vietnam, Argentina and China and at global scale. Uncertainty and decision analysis: Hall applied generalised theories of probability to civil engineering and environmental systems, including random set
