Before joining the University of Hong Kong, he was Senior Lecturer in Urban Design at the Cardiff University’s School of Geography and Planning.

His research interests are in spatial and urban design in relation to economic, social and environmental impacts, using spatial network design analysis to understand design properties of activity location systems of large conurbations in the USA, UK, France and China. At Cardiff University, he led the conceptual development of spatial design network analysis software (sDNA,

Alain was previously Executive and Board Director at the global consultancy Space Syntax Ltd. where he directed large scale projects concerning spatial policy analysis, urban design policy formulation and evidence-based spatial design in major cities including Paris, London, Boston, Shanghai. Clients included Greater London Authority and the London Boroughs. He has advised leading international urban design practices such as ARUP Associates, Atelier Jean Nouvel, Farrell & Partners, Foster + Partners, Gehry Partners, Herzog and de Meuron, Hopkins, Martha Schwarz & Partners, and Make.
