Departing from a broader demographic change perspective Gustavo is most probably the only living economist who does not see ageing as a problem. He has a Ph.D. from the Oslo Metropolitan University and a Master's degree in Economy and Public Policy from the University Institute of Lisbon, Portugal. My research focuses on population ageing under a broader demographic change perspective. When introducing myself I like to challenge my interlocutor by stating that I am the only living economist who does not see ageing as a problem. Despite the undeniable fact that increasing frailty is an important aspect of the ageing process, my research highlights the diversity of experiences people face under different contexts. I have paid special attention to the ageing process in an urban context. This approach is important as a bridge between disciplines. Population ageing is an unprecedented phenomenon with a global impact. At the same time, the magnitude and speed of that change is not homogeneous. By acknowledging the importance of the contextual and relational aspects, and combining those ideas with concrete analytical tools, I have opened the possibility to new approaches both for researchers and policy makers, in particular for economists and city planners. I have dedicated most of my career to investigating the ageing process in an urban context. Together with ageing, urbanization is the other major demographic trend shaping the organization of societies. I am particularly interested in the spatial relations within and surrounding cities. I am a lecturer at Oslo Metropolitan University and an associate researcher at DINÂMIA’CET – IUL, Centre for Socioeconomic and Territorial Studies in Portugal, an affiliate of the P2P Lab research collective (Greece/Estonia), and Associate Member at IESE, in Mozambique. I am also a member of the African Research on Ageing Network (AFRAN), lead by the Oxford Institute of Population Ageing.
