I am a cultural-digital geographer whose work examines digital technologies, negative affects, and the politics of refusal. More specifically, I examine how the politics of resistance shifts in relation to changing technological and urban conditions, and how, in turn, such negative politics push us to rethink geographical understandings of power, affect, and the human.

I am the author of the monograph 'Techno-Negative: A Long History of Refusing the Machine' (University of Minnesota Press, 2026). My research, while grounded in cultural and digital geography, is inspired by critical theory and pessimist philosophies. Methodologically, my work draws on qualitative, archival, and creative methods, with a focus on film. I have recently co-directed MACHINES IN FLAMES (2022; 49min), an experimental documentary about a group of French computer workers who bombed computer firms in the early 1980s, and BREACHED (2024; 15min), a chronicle of modern-day cargo looting.

I often make appearances in newspapers, magazines, and podcasts to discuss resistance to technology (past, present and future). Recently this has included features and interviews in the New York Times Magazine, New Yorker, Vox, New Zealand Post, Die Zeit and Computer Weekly, amongst others. 

My current research investigates the connections between AI and authoritarianism, and the various forms of refusal emergent in the face of the deepening saturation of Artificial Intelligences technologies into everyday life, what I refer to as 'AI-Pessimism'.
