As an academic Dr. Fleming has published over 40 articles and books, including Cycle Space, Architecture and Urban Design in the Age of the Bicycle, (NAi010, 2012) a book that promotes the bicycle as the chief paragon and protagonist of environmental design. With NAi010 he will publish his follow up book, Velotopia: A New Model for Urban Growth in 2017. Exhibitors of his design work include the National Museum of Australia with press coverage from CityLab, FastCompany, ArchDaily, etc.. He is a draw-card speaker to institutes of Architecture (New York, Rotterdam, Vancouver, Singapore, Sydney etc.) and major events (the launch of Europe by People, VeloCity, etc.) and is a brand ambassador for Shimano. He has held academic positions at the Universities of Canberra, Tasmania and Newcastle in Australia and Harvard and Columbia universities in the US and is a regular guest lecturer at the Harvard School of Public Health. As a government architect in Singapore he designed and project managed 4 major developments including a total of 1810 dwelling units and designed a 2.4 hectare park, an early example of his life mission to design active environments.
His design work is aimed at maximising the mode of maximum benefit to our health, wealth and planet, while at the same time dismantling the hegemony of car-centric planning that does more to hurt walking and public transport. He left a tenured academic position in 2015 to pursue this mission through practice.
