Joshua Dimasaka is an applied AI (doctoral) researcher at the UKRI EPSRC Centre for Doctoral Training in the Application of Artificial Intelligence to the study of Environmental Risks (AI4ER) of the University of Cambridge. He both develops benchmark datasets and investigates artificial intelligence methods to quantify exposure and risk of the built environment at large scales, enabling the beginnings of a global risk audit. His work measures the changes in disaster risk profiles over time to assess whether countries are making progress in reducing disaster risk, ultimately to inform our collective efforts on the Sendai Framework for Disaster Risk Reduction 2015-2030.
