Robert Nicholls has a long experience of analysing long-term coastal problems and solutions. Much of his work has focused on sea-level rise and climate change, necessitating an interdisciplinary approach. A distinctive dimension has been consideration of the coastal zone as a series of interacting systems which facilitates policy analysis. He contributed to the RegIS and CLIMSAVE integrated assessment efforts in UK and Europe, led the Tyndall Coastal Simulator, and is currently PI of a NERC UK-based project entitled "Coastal resilience in the face of sea-level rise". He also has extensive international and global experience, especially in coastal cities, deltas and small islands. He has advised national governments (e.g., UK, Netherlands, Bangladesh, Singapore, the Maldives) and intergovernmental organisations (e.g., OECD) on climate change and coastal issues He was a lead author to five reports of the Intergovernmental Panel for Climate Change (IPCC) assessment process, a review editor to the fifth IPCC assessment and a contributing author to recent the IPCC Special Report on the Oceans and Cryosphere (2019). His H Index is 91 (Google Scholar) and he is a Web of Science Highly Cited Researcher (2019 and 2020).He currently co-leads the World Climate Research Programme Sea-Level Rise Grand Challenge to deliver sea-level science to support better coastal impact and adaptation assessment and is a member of the ASCE/COPRI Coastal Engineering Research Council. On 1 October 2019, he became the Director of the Tyndall Centre for Climate Change Research based at the University of East Anglia.
