The Aston Institute for Forensic Linguistics is the leading hub for forensic linguistics worldwide. Set up as the Centre for Forensic Linguistics in 2008 by Malcolm Coulthard, it was expanded into a research institute with investment from Research England in 2019.

We are a thriving and lively community of over thirty members, from PhD students to professors, and our research is innovative, applied, interdisciplinary and impactful. In addition to conducting cutting-edge research, our members teach on the Aston MA in Forensic Linguistics, a programme that consistently enables graduates to secure careers in policing, intelligence analysis and related fields. We also run CPD courses and provide investigative assistance and expert evidence in criminal and civil cases.

Our diverse efforts are united by a common goal - improving the delivery of justice through the analysis of language.

We are organised into the following research clusters

LiDiLS

Title: Linguistic Disadvantage in Legal Settings (LiDiLS)
Coordinator: Dr Felicity Deamer

The central aim is to use linguistic methods to conduct analysis of the language used in a variety of legal settings to explore issues around vulnerability and disadvantage within the legal system. We aim to better understand how vulnerability and disadvantage can be caused, maintained, and shaped by the needs and procedures of the legal system. An enhanced understanding of these issues will facilitate better provision for vulnerable and disadvantaged individuals in myriad legal settings.


Projects

Ethical uncertainties and inconsistencies in diminished responsibility rulings

Examining ways in which uncertainties in the conceptual underpinnings of diminished responsibility are reflected in ethical uncertainties and inconsistencies in psychiatric evidence. Deamer and Wilkinson. (forthcoming). Ethical uncertainties and inconsistencies in diminished responsibility rulings: a case for psychiatric fictionalism.

SILC

Title: Spoken Interaction in Legal Contexts (SILC)
Coordinator: Dr Nicci MacLeod

The primary research focus is on investigative interviews in policing and other contexts (such as internal or civil investigations), but our remit encompasses other contexts where spoken interaction is central, such as courtroom interaction, emergency calls, and first response encounters. A key tenet of our approach is to work closely with practitioners and external organisations, in order to produce genuinely useful research informed by, and grounded in, professional practice.

Discursive Effects of a 'Pioneering Approach': Police interviews with rape victims in the context of Operation Bluestone Soteria - Dr Nicci MacLeod (BA/Leverhulme Small Grant 2023-2024)

This project scrutinised a set of investigative interviews carried out with victims of rape prior to the rolling out of changes enacted by the large-scale research programme Operation Soteria. It has identified a number of key areas of interviewing practice where recommendations from the programme might be put to use. This project served as a pilot for further research for which funding is currently being sought.

HALO

Title: Harmful and Abusive Language Online (HALO)
Coordinator: Dr Tahmineh Tayebi

Brings together work in the institute that focuses on the role of language in the composition and dissemination of hateful and dangerous ideologies in online spaces. From white supremacy to child sexual abuse, from transphobia to the so-called 'manosphere', and from misogyny to pro-suicide fora, discourse is at the heart of a range of dangerous online practices, and our work seeks to unpack these processes to shed light on how we might improve the safety of marginalised and/or vulnerable groups in the online sphere.


Projects

Online Offensive Language - Dr Tahmineh Tayebi (monograph in press)

In this project, we conduct a multi-layered, corpus-assisted analysis of offensive language across various social media platforms, focusing on the lexical, discursive, and pragmatic features.


Appraisal for Intelligence Analysis (AIA) - Dr Nicci MacLeod and Dr Madison Hunter (and formerly Professor Tim Grant (Externally Funded)

Testing the utility of Appraisal Theory for investigating and categorising harmful online discourse, with a view to semi-automating the process to assist with intelligence gathering.


Linguistically Enabled Analytic Dark Search-Engine (LEADS-Engine) - Dr Emily Chiang and Dr Krzystof Kredens (UKRI Innovate UK grant) 

A projects incorporating corpus linguistics tools into a search engine to assist commercial entities (e.g. Banks) in monitoring fraudulent activity on the dark web.


Hierarchies of Power - Dr Felicity Deamer (and formerly Professor Tim Grant) (Externally funded) 

To provide understanding and tools for the analysis of hierarchies of power across large datasets of anonymous online criminal interactions. Newsome-Chandler, H. & Grant, T. (2023) Language and Law / Linguagem e Direito, Vol. 10 (1)

FTA

Title: Forensic Text Analysis (FTA)
Coordinator: Dr Krzysztof Kredens

Researches individual variation in language use to inform the theory and practice of forensic authorship analysis. We are interested in linguistically-enabled offender identification, the identification of the native dialect or language of non-native speakers of English producing texts in English online, and the correlations between language use and age, and language use and personality.


Projects

100 Idiolects - Dr Krzysztof Kredens

A resource used to facilitate research on individual variation across discourse types.


Idiolectal stability in Spanish - Dr Krzysztof Kredens and Dr Andrea Celeste Mojedano Batel

A project investigating patterns of individual linguistic stability across discourse types using Spanish-language data

Forensic Linguistics International Summer School

2025 sees the nineteenth edition, once again held at Aston University.

The city campus is located in the heart of Birmingham, with easy access via rail, road, and air, and has plenty of attractions to discover during the evenings.

The Summer School addresses subjects within the broadly defined discipline of forensic linguistics, including the nature of legal language, forensic authorship analysis, linguistic copyright issues, plagiarism and its detection, and legal translation and interpreting.

We work with authentic language data and use real cases to illustrate theory.

We opt for maximum student involvement, and encourage critical inquiry and debate.

Each year, we invite leading scholars and practitioners in forensic linguistics to be our tutors.

This gives participants the unique opportunity to interact directly with those responsible for recent developments in the field of language and the law and forensic linguistics.

Our tutors have qualifications in linguistics and/or law and some have first-hand experience of providing expert evidence for courts of law.
