Research Interests: 

I carry out interdisciplinary research by compliling (electronic) language resources and particularly by recording linguistic data in corpora (linguistic annotation). My other research specialties are Turkish discourse, pragmatics and language acquisition. In the area of discourse, I am interested in discourse relations and discourse relational devices. I analyze (written) Turkish texts, investigate explicit and implicit ways of signalling discourse relations and try to specify the features that could be important for discourse relations. I have been the pricipal developer of Turkish Discourse Bank or TDB (an electronic resource of Turkish annotated for discourse relations in the Penn Discourse TreeBank style). Linguistically annotated corpora are ultimately inputs to language technologies and TDB is the platform where the results of our theoretical investigations are recorded. My corpus development efforts go hand in hand with my research on discourse mechanisms.

I am 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 was involved in the program committee or scientific committe of various interdisciplinary conferences and workshops, for example, Textlink - Structuring Discourse in Multilingual Europe: Second Action Conference, 2016; ISBCS 2014, 2015 (1st/2nd International Symposium on Brain and Cognitive Science); Language Resources and Evaluation Conference (LREC)  2012, 2014, 2015, 2016; Language and Resources area of Association of Computational Linguistics Conference (ACL) 2013, 2014, 2015, 2016. I also serve in the program committees of International Conference of Turkish Linguistics (ICTL) and National Turkish Linguistics Conferences (Ulusal Türk Dilbilim Kurultayı).

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 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: 


TDB 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 usually teach Cogs 541 Language Acquisition and Cogs 528 Discourse Mechanisms. You can access my research group Turkish Discourse Bank from here as well.

Thesis / Research Information: 

I supervise master's and PhD research projects on the topics described under Research Interests above; I welcome thesis propososals on those or on related areas. 

Here are the most recent master's and doctoral theses I supervised:
