My research addresses a central question in the contemporary study of political violence: under what conditions do online communities produce offline political action?
Conventional accounts of social movements and terrorism treat organizational unity, cohesion, and resource mobilization as necessary conditions for a movement to act. The online extreme right satisfies almost none of them. It is geographically dispersed, organizationally fragmented, demographically broad, and largely leaderless — and it has nonetheless produced a sustained wave of mass-casualty violence in which perpetrators reproduce the tactics, texts, and symbols of prior attackers. That mismatch between theory and observation is the puzzle my work is built around.
My answer is that digital platforms are not merely channels through which movements communicate, but constitutive environments in which political identities are formed, grievances are framed, and collective action is coordinated. The agenda that follows from this claim has theoretical, methodological, and substantive components.
Theoretical contribution
I develop a framework treating platforms as three things at once: identity laboratories, where members work out who counts as one of them; coordination infrastructure, which substitutes for formal organization; and meaning-making spaces, where a shared interpretation of political conditions is produced and maintained. Each carries distinct implications for mobilization potential, and each is observable in the traces communities leave behind.
Building on this framework, my dissertation argues that extreme-right collectivities generate violence when they establish durable social processes: the widespread adoption of apocalypticism, the crystallization of mobilizing artifacts such as canonical texts, and the establishment of a “canon” of attackers who are commemorated and imitated. These are informal processes, but they do the work that hierarchy and formal membership do in conventional movements.
Methodological contribution
Studying these processes requires measuring concepts that surveys and interviews cannot reach at scale, in communities that are hostile to observation. I build transformer-based classifiers to measure latent rhetorical constructs — apocalypticism, canonization — in very large corpora of forum text, and I pair those measures with designs that support causal claims. In my job market paper, a fine-tuned classifier applied to eleven years of 4chan /pol/ posts yields a time series of apocalyptic rhetoric, and intervention analysis shows that this rhetoric rises sharply in the immediate aftermath of mass-casualty attacks. In other chapters I use interrupted time-series and network contagion analysis to trace how mobilizing artifacts diffuse.
I take validation seriously as a substantive, not merely technical, matter: a classifier for a contested political concept is a measurement instrument, and I treat annotation design, inter-coder reliability, and error analysis as part of the argument rather than an appendix to it.
Substantive contribution
My empirical work shows how network structure, ideological coherence, and platform affordances shape when online extremism produces real-world violence. Published work traces the multi-node structure of neo-fascist accelerationism, the formation of extremist identity through performative infighting in gaming communities, and the radicalization risks posed by generative language models. Collectively, this research argues that counter-mobilization efforts aimed at individual groups will underperform, because the relevant unit is the background community from which attackers emerge.
Forward agenda
The next phase of this agenda extends the framework in two directions. First, to generative AI: I am currently studying polarization and political behavior in large language models under a Humane Studies Fellowship, building on my earlier work on language-model misuse. Second, comparatively: the measurement strategies I have developed for English-language communities are portable, and cross-national comparison of digital radicalization is the natural test of whether platform affordances or national political contexts do more of the explanatory work.
