Research Interests: 

My research specialties are Turkish discourse, pragmatics, linguistic annotation (recording linguistic data in corpora), and (second) language acquisition. In the area of discourse, I am particularly interested in discourse relations and discourse relational devices, such as connectives. I analyze (written) Turkish texts and investigate explicit and implicit ways of signalling discourse relations, and I try to specify the features that could be important for discourse relations. I have been the pricipal developer of Turkish Discourse Bank (a resource of Turkish annotated for discourse connectives in the PDTB style) and devote a lot my time to improving it by leading research projects where we annotate the corpus for more discourse relations and more features. My corpus development efforts go hand in hand with my research on discourse mechanisms.

I am also interested in initiating new research proposals and projects involving the development of corpora targeting various aspects of Turkish. I was recenlty involved in the development of a corpus of children's literature (with my thesis advisee Elif Ahsen Tolgay).  

I have also done research on lexical semantics, mainly the unaccusative-unergative distinction in Turkish (in collaboration with Cengiz Acartürk), language acquisition of relative clauses by Turkish children (with Duygu Özge), the acquisiton of requests by second language learners (together with G. Bahar Otcu-Grillman and Elif Yumun), and analysed the Turkish /r/ (with Çiler Hatipoğlu and Nart B. Atalay). 

I was involved in the program committee or scientific committe of various conferences and workshops, for example, ISBCS 2015 (2nd International Symposium on Brain and Cognitive Science), 17th International Conference of Turkish Linguistics (ICTL 2014), ISBCS 2014 (1st International Symposium on Brain and Cognitive Science)LREC 2014, ACL 2014Ulusal Türk Dilbilimi Kurultayı 2014/National Turkish Linguistics Conference 2014, Language and Resources area for ACL 2013.

I was one of the organizers of 16th International Conference of Turkish Linguistics (ICTL), and LAEL (Linguistic Approaches to Endangered Languages: Theory and Description). 


I am the Editor in Chief of Dilbilim Araştırmaları Dergisi/Journal of Linguistic Research, one of the oldest peer-reviewed journals of linguistics in Turkey publishing research articles (primarily) on Turkish.  


Funded projects: 


I am the primary investigator of Annotating Implicit Discourse Relations, a Scientific Research Project (BAP) funded by Middle East Technical University. The project aims to annotate a small portion of Turkish Discourse Bank (TDB) for implicit discourse relations. TDB itself was built with a grant from TÜBİTAK, The Scientific and Technological Research Council of Turkey (2008-2011), where I was the primary investigator: Turkish Discourse Bank Project.


I am part of Textlink: Structuring Discourse in Multilingual Europe (ISCH COST Action IS1312), where I act as the Communication Manager and as a member of the Steering Committee. 


Between 2008-2010, I was part of the project Electronic In-Service Training for Novice English Teachers (e-INSET-NET), funded by Leonardo, Transfer of Innovation Projects (Principal Investigator: Fidel Çakmak, Mersin University). 

Courses / Laboratories: 

I teach Cogs 541 Language Acquisition, Cogs 528 Discourse Mechanisms, and Cogs 503 Introduction to Cognitive Science.

You can access my research group Turkish Discourse Bank from here as well.

Thesis / Research Information: 

I supervise master's and PhD research projects mainly on discourse, pragmatics, second language acquisition and lexical semantics. I welcome thesis proposals from graduate students on any of these topics as well as proposals regarding the development of corpora targeting these issues.  

In 2014, I supervised one PhD thesis: 

Assessment of the Turkish Discourse Bank and a Cascaded Model to Automatically Identify Discursive Phrasal Expressions in Turkish by Ayışığı B. Sevdik-Çallı 

and the following Master's theses:

A Turkish Database for Psycholinguistic Studies: A Corpus Based Study on Frequency, Age of Acquisition and Imageability by Elif Ahsen Tolgay,  
Discovering the Discourse Role Of Converbs in Turkish, by Ahmet Faruk Acar,
An investigation Of Directive Speech Acts in L2 Learners E-Mails, by Mediha Toraman,
