About me

Achilleas Kostoulas
Hello, and welcome to my site!

I am an applied linguist, specialising in language education and (second language) teacher development. My research focuses on various aspects of language education, often seen through the lens of Complex Systems Theory. My recent book, A Language School as a Complex System (2018), provides an example of how this might be done. I also have a keen interest in the psychological processes associated with teaching and learning. This interest has led to the publication of Language Teacher Psychology (2018), a volume that I co-edited with Sarah Mercer. You can find a more comprehensive list of my published work here.

Academic appointments

I work at the Department of Primary Education, at the University of Thessaly in Greece. In this role, I am involved in the delivery of applied linguistics and language education courses. I also take an active role in the coordination of the teacher practicum. You can find out more about the courses I teach in this page. In addition, I am in charge of the teacher practicum at the Language Education for Refugees and Migrants postgraduate programme at the Hellenic Open University.

Before that, my most recent academic role was Visiting Research Fellow at The University of Manchester (UK) (up to February 2020). In this post, I worked on a project that led to the publication of a research monograph, entitled The Intentional Dynamics of TESOL (De Gruyter, with Juup Stelma).

Previously, I was employed as a post-doctoral research associate in the Department of English Studies at the University of Graz, in Austria. In addition to my research, this appointment involved the delivery of ELT and Applied Linguistics courses. I also taught ad hoc modules and workshops on research methods and academic writing.

Other past appointments have taken me to the University of Manchester, where I was entrusted with MA supervision; and the Epirus Institute of Technology (which has since been merged the University of Ioannina), where I was responsible for the delivery of English Language and Language Teacher Education courses.

In the past, I worked in various teaching and managerial capacities in primary and secondary schools in Greece. The most recent of these appointments was at the University of Ioannina 2nd Model/Experimental Primary School (Β’ Πρότυπο Πειραματικό Δημοτικό Σχολείο Ιωαννίνων).

Academic background

I completed my doctoral studies at The University of Manchester, from where I received a PhD in Education (TESOL) in 2015. I also hold an MA in Teaching English to Speakers of Other Languages from The University of Manchester, and a BA in English Studies from the University of Athens. You can find additional information about my academic background in this page.

In this site, I have put together some information about myself and my academic work, which I hope you find of interest. This site also hosts my (irregularly updated) blog, where I record information that I find interesting, as well as comments on English language education and research methods. You can also access my podcast [in Modern Greek], which explores introductory concepts about linguistics.

Do take a look around, and feel free to contact me for comments or questions.
