Richard Teeuw is Principal Lecturer and Course Leader for the Crisis and Disaster Management master’s program in the School of Earth and Environmental Sciences at the University of Portsmouth. He has over 30 years’ experience in applied geomorphology and remote sensing, initially specializing in tropical alluvial gold and diamond deposits, following his PhD research in Sierra Leone. Dr. Teeuw’s current research focus is on data poverty and low-cost approaches to using satellite imagery for assessing hazards, vulnerability, and risk, as well as geoinformatic capacity building in low-income countries. His research includes industry-funded projects from neighborhood-scale mapping of flood risk in the UK to satellite remote sensing of artisanal oil refining and associated pollution in the Niger Delta as well as uses of free satellite remote sensing data for water resource management in Sierra Leone. Dr. Teeuw was awarded a Leverhulme Trust research grant to examine uses of low-cost remote sensing for disaster risk reduction in coastal districts and has been funded by the Royal Geographical Society to carry out surveys of coastal geohazards around Dominica. Since 2016, he been researching the uses of free satellite imagery to monitor the impacts of illegal gold mining on rainforest and rivers in Colombia. He can be reached at richard.teeuw@port.ac.uk.
