I study people, code, and inequality.
Assistant Professor at the University of Amsterdam's Informatics Institute and Coordinator of the User Interaction Lab. I study how gender and social dynamics shape the way we build technology, combining data science with critical, participatory methods. Previously at Oxford and the LSE.
Gender, Coherence & the Ontological Politics of Generative AI
With Delfina Martinez Pandiani (they/them; humandigitalist.com), in Oxford Intersections: Gender Justice. Published 14 August 2026.
Generative AI systems do not merely hallucinate facts. They increasingly hallucinate subjects. This article develops a queer and technofeminist account of generative AI hallucination as ontological subject production, a political infrastructure of subjectivity disguised as mere technical error. While hallucination is conventionally described as “plausible yet non-factual content,” a deeper function is the fabrication of subjects along normative regimes: intelligible only insofar as they conform to norms of gendered coherence, and materially produced through extractivist data and labor regimes. This article introduces two interlocking concepts through which this operates: (a) the hallucinated human subject, the statistically assembled figure of personhood that generative systems construct as a “you” from users’ digital traces; and (b) the hallucinated machinic subject, the synthetic speaking position through which AI presents itself as a coherent “I.” Drawing on Preciado’s pharmacopornographic regime, Butler’s performativity, and Althusser’s interpellation, this article argues that these two figures recursively stabilize one another, producing closed circuits of gendered intelligibility in which contradiction is compressed, queerness is corrected, and normative coherence is enforced at scale. This dynamic is traced across three sites: the algorithmic construction of the datafied human double, the constitutional training of the machinic persona, and the recursive feedback loop through which each figure stabilizes the other. Hallucinated subjects are experienced as real, and the gendered categories they reinforce are already being written into the next generation of governance and surveillance systems. Because hallucination is not a technical flaw to be corrected, but a political infrastructure of subjectivation that enforces (gendered) coherence, queer refusals and glitches that trouble prediction become a crucial site of resistance.

My group is recruiting developers to evaluate an IDE task-management extension co-designed with and for neurodivergent women developers. Online sessions, around an hour.
Co-founded a new network at the University of Amsterdam for queer and feminist work in computing, launched at Lab42 with talks, workshops and a community poster session.
Led a speculative design workshop on how algorithmic systems construct and infer our identities, working with feminist strategies of Opacity, Excess and Punto de Fuga.
A 3-year project with the Digital Interactions Lab: “Human-Centered Code: Building Accessible IDEs for Neurodiverse Women in Computing Education.”
Spanning human–computer interaction, data science, philosophy and the critical, intersectional study of technology, asking who gets to participate, and how we build more equitable systems.
I study how gender and intersecting inequalities shape who is seen as a “real” programmer, and what that recognition does to participation in computing. Combining large-scale computational methods with ethnography, I trace coding style and reputation on GitHub and Stack Overflow, the meme cultures of hackathons (the Programmed Differently strand), and field experiments on hiring in online labour markets.
Questions I ask
I work on the philosophy and politics of AI: what generative systems assume about us, and what they make of us. I treat coherence, inference and “hallucination” as ontological and political acts, and ask about the epistemic injustice built into how data and models decide whose knowledge counts.
Questions I ask
I design and study technologies for bodies and conditions that mainstream tech overlooks, focusing on endometriosis, menstrual and cycle health. Using feminist HCI and participatory methods, I examine how people turn to AI for self-diagnosis, and how we might build privacy-first tools that take embodied, intersecting experience seriously.
Questions I ask
Through my NWO Veni project Human-Centered Code, I build accessible, AI-powered programming environments designed around neurodivergent cognition, co-designed with and for neurodivergent women in computing education.
Questions I ask
I coordinate the User Interaction Lab (UIL), a hands-on facility in LAB42 for project-based research and teaching in human-centred computing. It opened in December 2025.
Eye trackers, health and wearable sensors, and professional audio and video kit for project-based experimentation, reflection and user research.
Central to the Institute's shift toward Human-Centred Computing, including the new MSc HCI track and courses such as the Data Systems Project.

Brooke, S. (2025). Masculinity, femininity, and queering inclusion at hackathons. Proceedings of CHI 2025, Yokohama. · ★ Best Paper (top 5%)
An ethnographic study of how masculinity and femininity are performed at hackathons, and how inclusion can be queered rather than assumed. Recognised with a CHI 2025 Best Paper Award (top 5% of submissions).
Brooke, S., & Rao, A. H. (2024). Testing platform interventions to minimise discrimination in online labour markets. Big Data & Society, 11(1). · DOI
Online labour markets are a vital source of income for globally dispersed freelancers, yet they perpetuate hiring discrimination through their design. Using a design-justice methodology, a survey, interviews and a discrete-choice experiment on a purpose-built mock platform, we identify design interventions, including community composition and identity-signalling flairs, that reduce discrimination against women and non-White freelancers, and show that anonymity universally disadvantages freelancers.
Brooke, S. (2024). Testing for gender differences in Python programming style and quality on GitHub. Journal of Computer-Mediated Communication, 29(1). · DOI
Treating code as communication, this study examines 1,728 open-source projects for gender differences in Python style and quality (adherence to PEP-8). It finds significant differences in structure and organisation but no difference in code quality, and shows a programmer's gender can be predicted from coding style, concluding that gender differences in code are a matter of style, not quality.
Brooke, S. (2022). Gender in remixing and sharing memes at hackathons. Proceedings of CHI '22, Article 395, 1–14. · DOI
Drawing on a multi-sited ethnography of seven hackathons, this paper shows how memes and informal technology culture shape socialising, and how even mundane memes can reveal the toxic masculinity and ideology of incels. It ends with recommendations for increasing inclusivity at hackathons.
Brooke, S. (2021). Gender biases in sharing and recognising technical knowledge on Stack Overflow. Information, Communication & Society, 24(14), 2081–2112. · DOI
Using a non-binary gender identification across 11 years of Stack Overflow activity, this study finds that recognition of technical knowledge is shaped by gender, feminine users receive lower scores despite higher effort, and that interaction is organised by gender, with recommendations for more inclusive online forums.

I designed and coordinate every course below at the UvA Informatics Institute, pairing critical theory with hands-on practice.
An innovative course I designed to teach theory through programming: students pair critical frameworks (panopticism, biopolitics, feminist epistemology, design justice) with hands-on Python/R analysis. The aim is to use empirical methods critically, building one cumulative notebook across the term and embracing exploratory “vibe coding” over optimisation, so theory becomes a practical analytical tool.
A hands-on capstone in which students build a working data system end to end. I run the technical prototyping workshops and the methodology lectures on critical approaches to data, pairing engineering practice with reflection on power and accountability.
A master's course on speculative design and research methods. Students examine how digital technologies shape everyday life across social, playful, inclusive and sustainable “lenses”, then develop a research proposal and speculative design project, aligning theory, methodology and ethics.
