I am a lecturer at the Manchester School of Architecture and a member of the Urban Infrastructure Transition Lab. I have been in research for nearly a decade and have previously worked in the tech and design industries.
I aspire to build more livable cities through research and public service. Using a mixed-method research design, I study how pandemic-induced street experiments impact public space use. I have researched topics including walkability, bikeability, network connectivity, and TOD travel behaviour.
