About Me

Welcome to my blog post. I am Refat Aljumily, a junior quantitative criminologist, forensic linguist, and computational stylometrist, and, from a professional point of view, freelance researcher and lecturer. I have finally decided that I need a personal blog, so I have contacted Dr Liam Leonard to join ICA and he kindly accepted me as a member to start with something new, bold, and practically-made to increase my engagement with the academic community and get closer to my valued colleagues and readers to learn and share ideas with them.

I obtained my BA degree in English Language and Education at the university of Baghdad-college of Education (Iraq) in 1999 and my MA degree in English Linguistics at the university of Baghdad-college of Languages (Iraq) in 2006 under the supervision of Prof. Abedulwhid M. Muslit. During the bachelor and master university studies from 1999 to 2006, I was also working for the Iraqi Ministry of Interior (IMO) 1994-2007. I held policing posts, where I had responsibility for a number of different policing operations in the areas of tactical crime analysis, administrative crime analysis, and police personnel training and development.

Following 13 years in policing, I returned to academia. In September 2009, I joined the PhD program (PT) at the university of Newcastle (Newcastle upon Tyne, UK) under the supervisor of Dr. Hermann Moisl and Prof. Mike Rossington. My Ph.D. study was Computational Stylometry. I used this approach to examine the question of the authorship of the anonymous 1821 translation of Goethe’s Faustus with reference to nine candidate authors using a very large corpus of their respective writings based on the usage of function words applying five cluster analytical methods: Four hierarchical linear methods (Single, Average, Complete, Ward), two linear non-hierarchical methods (PCA and MDS), and two non-linear methods (SOM and Isomap).

In the course of my PhD study, I first fell in love with the techniques of Stylometry when I started to read “Faustus from the German of Goethetranslated by Samuel Taylor Coleridge edited by Frederick Burwick and James McKusick, 2007 (Oxford University Press), and when I started to read a great deal about the evolution of Stylometryin humanities scholarship and digital humanities. In particular, I was inspired by theideas of Dr. David Holmes, a modern day Sherlock, (College of New Jersey-School of Science). Throughout my reading, I found thatStylometry has legal as well as academic and literary applications ranging from the questions of the authorship of disputed works to forensic linguistics.

When completing my PhD in (September 2015), for which my thesis addressed certain aspects of forensic linguistics and authorship attribution, I have continued the same line of study and research by putting my knowledge of (e.g. corpus linguistics, forensic linguistics, quantitative criminology, and multivariate analytical methods)into practiceto create a strong research profile and to see the results of my hard work going to print and being read by academic scholars and students.In these works I conducted different research projects, applied different research methodologies, used different analytical methods, the aim of which, for example, was to generate a hypothesis about an author, text, genre, or to evaluate different sources of crime data. My publications includes:

My Response to Anna Sergi’s post “Italian judges remove children from Mafia families to stop criminal traditions passing to next generation” in National Post. This post is available from:

Refat Aljumily. (2016). To Mr Jeffrey Beall: Bring forth your evidence, if you're telling the truth! https:///

My recent completed work is:

Bayesian Statistics for Measuring the “Dark Figure of Crime”. In this work, I proposed a methodology to measure the "dark figure" of crime and estimate the rate of unrecorded crimes or reported crimes but unrecorded occur in society. This work has not been published yet, but the abstract is available  at

I currently act as a reviewer for the journal of Studies in Media and Communications in my areas of interest (quantitative criminology, forensic linguistics, and stylometry) and in March 2016 joined the Editorial board.
