Welcome
I am currently a postdoctoral researcher in the Prominence in Language project at the University of Cologne, Germany. I'm working with Prof. Klaus Von Heusinger. We are investigating referential and conceptual activation in the processing of referential expressions in discourse. This is a great experience for me because SFB, funding, will provide me an opportunity to collaborate with leading professors in the clinical research and EEG field. This project is a great opportunity to increase the diversity of my research experiences.
I have just completed a three-year position as a postdoctoral research associate with the DALI (Disagreements and Language Interpretation) project at Queen Mary University of London. Working with Prof. Massimo Poesio, I have been investigating disagreements on anaphoric expressions and whether anaphoric references are resolved in natural-language processing. I have benefited greatly from the opportunity to work with computational linguists, machine-learning experts and game designers in seeking to better understand whether natural language expressions are always unambiguous in context.
I have been working on language usage of people with schizophrenia, their relatives and healthy comparator subjects (See Psychosis and Language Study [PaLS] below). In a new project (Spring 2019), I’m collaborating with Prof. Wolfram Hinzen & Dr. Emre Bora to examine the language use of Turkish patients with schizophrenia, their relatives and healthy comparator subjects. In addition, with Dr. Stuart Watson & Dr. Sinead Mullally (Institute of Neuroscience at Newcastle University) I am investigating emotional neglect and its impact on language use and hippocampus function.
Before my DALI post, I was a post-doctoral researcher at Durham University and the Institute of Neuroscience at the University of Newcastle, UK, where I worked with Prof. Wolfram Hinzen on PaLS, which was funded by the Arts and Humanities Research Council. This project investigated language usage of people with schizophrenia, their relatives, and healthy comparator subjects. We sought to understand this disorder in order to allow the development of effective cognitive behaviour therapy for people with psychotic disorders. It was an exciting international collaboration of linguists, psycholinguists, philosophers, and psychiatrists.
In addition to the above-mentioned partnerships, I continue to collaborate with Prof. Fernanda Ferreira of the University of California, Davis on the processing of anaphora and sentence disfluencies, Dr. Patrick Sturt of Edinburgh University on anaphora processing in written discourse, and with Prof. Ted Sanders and Prof. Deniz Zeyrek on a Textlink project on that
explores subjectivity in Turkish causal connectives.
My PhD training – during which I investigated deixis and sentence processing – involved a dual-university collaboration between the Middle East Technical University (METU), Ankara, Turkey and Edinburgh University. After obtaining my PhD, I was a post-doctoral researcher at the Institute for Mind and Brain at the University of South Carolina (USC) and University of California, Davis (UCD), working with Prof. Fernanda Ferreira.

A New Look at Discourse Deixis: a contrastive analysis
My first book! This was published by VDM Verlag in 2010. You can see more details (or even buy it!) here. The following is from the jacket blurb:
To date, most studies on 'this' and 'that' have focused upon their place in spoken discourse, defining their functions on the basis of a handful of selected examples and largely neglecting their broader roles within discourse structures. Analysis of their roles in written discourse has remained limited and tentative. This book aims to address this by carrying out a contrastive analysis of the pronominal uses of 'this' and 'that' within the written academic corpus, investigating their discursive roles in the light of the tenets of Centering and Rhetorical Structure theories in order to further our understanding of their pragmatic functions. It examines occurrences of 'this' and 'that' in terms of syntax and pragmatics, and describes the circumstances under which'this' or 'that' is preferred. It sheds interesting new light on the written use of 'this' and 'that' and will be of especial interest to linguists and to instructors in written English as either a first or a second language.
