Reflections on five years of the Summer Institute in Urban Studies

This critical commentary introduces the Summer Institute in Urban Studies (SIUS) in the context of the wider inter-disciplinary discussions over the future of urban studies. It outlines the context out of which the institute first took place in Manchester in 2014 and how it has evolved across four subsequent iterations, the most recent of which was held in Singapore in July 2018. We document and discuss the profile of those who have participated in the four institutes and reflect upon some of the challenges that have emerged through discussions on the current state of the field of urban studies and its various possible futures. In conclusion, this critical commentary reflects on what we have learnt from the four institutes to date as we plan for #SIUS2020
