Doctoral Research

My PhD research, completed at The Bartlett School of Architecture in 2024, focused on techniques for measuring and mapping rooftop housing. I provided a spatial analysis of airspace development in London between 2008/09 and 2018/19. I also developed several techniques as part of my doctoral research such as the Fresnel Map and Space Ratio. Here are a selection of maps and charts from my thesis.
