Viktor Roezer

Research Officer

Viktor joined the Grantham Research Institute on Climate Change and the Environment in December 2018. He works as a research officer on the Zurich Flood Resilience Alliance (ZFRA) project. His work will focus on flood resilience in urban areas in an OECD context. He is interested in the quantification of flood impacts and incentives for increasing pre-event flood resilience.


Viktor completed his PhD at the Institute of Earth and Environmental Science, University of Potsdam, Germany. He worked as a research assistant at the Hydrology group at the German Research Centre for Geosciences. His thesis focuses on the impacts of urban flooding with a focus on the coping capacity of private households. He completed his undergraduate degree in Geography at Ludwig-Maximilians-University Munich and holds a master’s degree in Environmental Hydrology from the Free University of Berlin. He has previously taught courses in Statistics at the Geography Department at Humboldt University in Berlin. Viktor also worked as a data scientist for an e-commerce start-up, developing predictive models.
