Research

My research examines armed conflict, terrorism, and political violence as it unfolds both online and offline. With a background in peace and conflict studies conducting on-the-ground fieldwork in the Middle East, my research is driven by the recognition that what occurs online can have significant impact on offline outcomes, and vice versa. Only examining the online or offline dimensions of political violence and contentious politics can leave significant gaps in our understanding of how conflict onset, processes, and outcomes. The existing divisions between online and offline investigations of terrorism and violent and extremism is striking, but it limits the explanatory power we can bring to bear on this complex phenomenon. Monitoring jihadist groups or far-right extremists online may be a first step for many researchers, but collecting fine-grained data in the real world is essential to understand the fuller picture and validate hypotheses. While online research is more accessible for new researchers to get started with, we often need to understand on-the-ground conflict dynamics to develop comprehensive explanations of how terrorist groups and violent extremists organize, recruit, and fight. 

 

My work seeks to bridge this gap by collecting fine-grained data both from detailed fieldwork (including subnational surveys, psychosocial measures, and elite/non-elite interviews with combatants, officials, and civilians) alongside primary source documents including online extremist propaganda, government records, and local media reporting to reconstruct complex conflict processes from multiple sources. Using process tracing and leveraging theoretical models from political science, sociology, and development studies to validate these theories we can gain new insights into the micro-dynamics of conflict and extremism.

Conflict, Extremism, and Political Violence

Inter-Rebel Competition & Consolidation

Syria, Civil War, Jihadist Groups, Extremism

What makes one jihadist group or armed actor emerge as the largest rebel group in a conflict? Utilising a mixed-methods approach, my research examines how Jihadist-Salafist rebel groups compete and consolidate their control over rival insurgent groups and civil society actors during multi-party civil wars. The majority of research on conflict and extremism considers how rebel groups fight against governments, but little analysis has considered how rebel groups fight and compete with each other. This is form of intra-rebel conflict often accounts for more than half of the conflict events within civil wars and is essential to understanding conflict dynamics. Where the academic literature has considered inter-rebel conflict, it is often too narrowly focussed on fighting, ignoring a much broader typology of inter-rebel interactions which includes alliance-formation, poaching, bargaining, cooperating, and economic coordination. While nationalist rebels have received some attention within peace and conflict studies, the consolidation practices of Jihadist-Salafist groups remain almost entirely unstudied, despite the presense of such groups in more than 50% of active

conflicts around the world. My research fills some of these gaps in our understanding of inter-rebel conflict by examining the sources of inter-rebel competition and consolidation within the Syrian Civil War. The Syrian Conflict, which began with hundreds of rival rebel groups have gradually narrowed to include only a few major factions, with the role of the largest cohesive groups being occupied by Hay'at Tahrir al-Sham (HTS). This research seeks to examine groups such as Hayat Tahrir al-Sham (Al-Nusra / HTS), Islamic State of Iraq and al-Sham (ISIL / ISIS), Jamaat Nusrat al-Islam wal Muslimeen (JNIM), and the Afghan Taliban (AT). As part of this project, multiple factors and mechanisms, including outbidding, rebel governance, media, and foreign fighters are examined in relation to rebel consolidation.

Countering Terrorist and Violent Extremist Content (TVEC)

My research with the Global Network on Extremism & Technology (GNET) and my practitioner work with the Global Internet Forum to Counter Terrorism (GIFCT) seeks to explain how extremist actors (including Jihadist-Salafist and Far-Right extremist groups) exploit new online platforms and AI systems to recruit, organise, and spread propaganda which results in offline harms. My current research examines how these extremist groups increasingly use encrypted social media platforms (Rocket.Chat, Telegram, TamTam Messenger Signal) to communicate privately, and seeks to measure the response and regulatory policies of these technology firms. While the online eco-system has become a lot more challenging for extremist actors over the past 10 years, there remain significant gaps in online security which allow these actors to keep leveraging major platforms as well as alternative sites. This research with the Oxford Disinformation & Extremism Lab (OxDEL) takes advantage of the large data sets publicly available to generate insights into the views of individual extremists and broader extremists groups surrounding major debates playing out in the public discourse (stretching from pandemics to elections to military interventions). Lastly, my research addresses the constantly evolving methods and loopholes employed by extremists to use evade detection and community standards on major social media platforms. The methods evading automated moderation include leetspeak, broken text posting, image obscuration, fuzzy matching, and secondary indicators to reduce false positives and identify extremist content more accurately at scale.

AI Security & Emerging Online Harms

My research on AI security with The Alan Turing Institute's Centre for Emerging Technology & Security (CETaS) explores the potential of commercially-available targeted advertising technologies to address online extremism and disinformation. In particular it is focussed on how to best identify individual users who are interested in extremist content or disinformation and offer a different and more reliable source of information. While much of the existing research understandingly focusses on explaining how and why extremist groups exploit online harms, much less has considered the positive interventions that online tools can offer in countering extremism. The technology itself remains neutral whiles its applications determine the net impact. Redirect methods offer compelling and targeted approaches to tailor our message to reach users who are vulnerable to extremism, but there is still limited data and analysis on the best practices and long-term impact of this methodology.  The primary research focus of this project centres on users who are only beginning to explore extremist content as opposed to long-term consumers of this content and therefore less likely to be responsive to online treatments. While click-through rates remain relatively low when compared with commercial advertising, even low engagement can lead to lower risks of violent extremism. Future research in this field will centre on the role of empathy, humour, and psychology in developing redirect tools that meet users where they are and engage them with social support networks beyond simply counter-messaging.
