Korff, M.


Dr. Mandy Korff is part-time Associate Professor in Geotechnical Practice (since 2016), and a Senior Advisor and Innovations Manager at Deltares. She works in the fields of underground construction, behaviour of piles, risk management and monitoring, observational method, forensic geo-engineering, soil-structure interaction, liquefaction, and impact of construction activities and earthquakes on structures. Her research is directly related to projects such as the Groningen earthquake studies, Amsterdam subway (North South line), Delft railway tunnel and projects in Singapore. Dr. Korff was chair of the Geotechnical Department of the Royal Institute of Engineers (KIVI) and the national representative for the ISSMGE during 2008-2017. She is currently a member of ISSMGE’s TC204 and TC207 on Underground Construction and Soil-Structure Interaction, and serves on the Corporate Associates Presidential Group.

Dr. Korff received her PhD from University of Cambridge in 2013, where she worked with professor Robert Mair on the Response of Piled Buildings to the Construction of Deep Excavations. Mandy Korff graduated from Delft University of Technology as MSc. in 1999 in Civil Engineering. In 2000 she joined GeoDelft as a consultant and researcher in the field of foundations and underground construction. She gained experience in geotechnical risk management. Many of her projects included some sort of forensic engineering and impact assessment related to underground construction works.
