Roshanka Ranasinghe (Kandy, Sri Lanka, 1967) is a Coastal Engineering Professor in the Netherlands. He holds the AXA Chair in Climate Change Impacts and Coastal Risk at the Department of Coastal and Urban Risk and Resilience, IHE Delft Institute for Water Education.[1] He is also a Professor  at the Department of Water Engineering and Management, University of Twente, and a Senior Specialist at the Department of Resilient Ports and Coasts (Hydraulic Engineering Unit) at Deltares.[2]

Biography

[edit]

Education and Career

[edit]

Roshanka Ranasinghe obtained his entire school education at Trinity College, Kandy in Sri Lanka. He completed his undergraduate studies in Civil Engineering in 1993 at the University of Peradeniya, Sri Lanka, where he graduated with First Class Honours. In 1998, Ranasinghe received his doctorate in Coastal Engineering and Oceanography at the Centre for Water Research (CWR), University of Western Australia (Perth, Australia). His doctoral thesis was titled "Dynamics of Seasonally Open Tidal Inlets[3]."

Since then, he has authored over 200 peer-reviewed articles and delivered numerous presentations worldwide.[1] He has worked in both the academic and government sectors in Australia and the Netherlands.[1]

Academic positions

[edit]

From 2008 to 2014, Ranasinghe was Associate Professor in Coastal Engineering at the Department of Water Engineering at UNESCO-IHE and the Faculty of Civil Engineering at the Delft University of Technology, and since 2014, he is the Professor of Climate Change Impacts and Coastal Risk at IHE Delft.[1] In 2015, he also joined the University of Twente as a Professor in the Department of Water Engineering and Management, a position he still holds.[1] From 2018 to 2020 Ranasinghe was the Head of the Department of Water Science and Engineering at IHE Delft, and from 2020 to 2022 he was the Head of the Department of Coastal and Urban Risk and Resilience at IHE Delft. Currently he is the Head of the Research group on Climate resilience Coasts and Cities at IHE Delft.

Advisory and professional activities

[edit]

Ranasinghe has supervised/co-supervised 25+ PhD candidates and numerous MSc students. He also has led a number of advisory and capacity development projects in several countries, including Sri Lanka, India, Vietnam, Thailand, Sao Tome and Principe, and Australia.[1]

Ranasinghe led the development of Coastal Futures,[4] an online tool launched in 2021 by IHE Delft that offers a comprehensive overview of state-of-the-art, global scale[5] projections for sea level rise, coastal flooding, shoreline retreat, and extreme waves.[6] This tool integrates multiple global data sets on coastal climate impact-drivers, providing users with a clear, up-to-date picture of potential future coastal hazards.[6]

Ranasinghe has also been actively involved in the Intergovernmental Panel on Climate Change (IPCC) process and is currently a member of the IPCC Seventh Assessment Report (AR7) Scoping Team (Working Group I). In the IPCC AR6[7] cycle, he was Coordinating Lead Author in Chapter 12,[8] a Lead Author of the Summary for Policy Makers,[9] and a Contributing Author in Chapters 9, 11 and Atlas of the Working Group I contribution to the IPCC Sixth Assessment Report (AR6).[10] Ranasinghe was also a Contributing Author in the IPCC Special Report on Oceans and Cryosphere in a Changing Climate (SROCC).[10]

Ranasinghe has been instrumental in the development of novel probabilistic, reduced complexity models, such as PCR,[11] SMIC,[12] and G-SMIC[13] for assessing climate change induced coastal risks. He has also been a key contributor to the development of several widely used global scale projections of climate change driven coastal hazards, such as extreme sea levels, coastal flooding and shoreline retreat.[14]
