Head of the Centre for Disaster Resilience and Associate Professor in Geotechnical Engineering for natural hazard risk management

About Me

My personal drive in my work is rooted in a deep and enduring concern with how geo-environmental science and engineering can tackle pressing issues of sustainable development and societal well-being and I defined myself as a broad-based, multi-disciplinary researcher. I have a background in environmental/geotechnical engineering with several years of experience working in geoscience and engineering geology. My approach in both teaching and research integrates experimental and numerical modelling with field studies, remote sensing, and, more recently, Internet of Things, sensor networks and interdisciplinary collaborations to address complex and cascading geo-hazards with creativity and innovation.

I am Head of the Centre for Disaster Resilience (itc.nl/cdr) where I am working with my colleagues at ITC and with our partners, focusing our fundamental, interdisciplinary and applied research, dissemination, education and training, (international) cooperation, and advisory services on a synergetic and common effort to increase the well-being and the global sustainable growth by significantly decreasing disaster risk

Engineering & Materials Science


Study of geophysical fluid and granular flow dynamics processes with a multi-disciplinary approach, through experimental and numerical modelling. Hazard and risk assessment of multiple and complex volcanic and landslide phenomena, e.g. debris flows and rock avalanches, lahars and tephra fallout, mass flow induced tsunamis. More recently I am developing and becoming more and more interested in the use of data mining, crowd sourcing, smart sensors and machine learning applied to geo-environmental risks and citizen science.
