Cassidy Johnson is a Senior Lecturer at the Bartlett Development Planning Unit, University College London. She has a background in urban studies and minimum cost housing, with a focus on low and middle-income countries. Her interests are concerned with how communities and governments can prepare urban areas to be resilient to and respond to disasters, and the implications of forced evictions in cities. She has done research on post-disaster temporary housing - particularly looking at disaster recovery in Turkey and on urban rehabilitation and Roman communities in Istanbul. She has also worked with Natural Resources Canada on the use of solar energy in cities. Cassidy is a founding member of Information and Research for Reconstruction Network (i-Rec) and coordinator of CIB Task Group 63, Disasters and the Built Environment.
