Hasan Dikyuva

Hasan Dikyuva is a Deaf PhD researcher in the Multimodal Language Department at the Max Planck Institute for Psycholinguistics and the University of Amsterdam, where he is part of the International Max Planck Research School. He is co-supervised by Prof. Dr. Aslı Özyürek, Assoc. Prof. Dr. Beyza Sümer, and Assoc. Prof. Dr. Roland Pfau.

His doctoral research focuses on the expression of negation in Turkish Sign Language (TİD). Using large-scale corpus data, he investigates how manual and non-manual markers interact in the grammatical and discourse-level realization of negation. His work contributes to sign language linguistics, multimodal grammar, and cross-linguistic typology.

Hasan has over twenty years of experience in sign language research and documentation. He is a co-author of the Turkish Sign Language Grammar and was one of the main researchers involved in the development of the first comprehensive Turkish Sign Language dictionary (tidsozluk.net). He has also worked on endangered village sign languages, including Mardin Sign Language, in international research projects.

In addition to his academic work, Hasan has been actively involved in Deaf organizations at national and international levels, contributing to research-informed advocacy and community-based initiatives.
