About Me
Hi there! I’m Onur Keleş, a PhD student in the Department of Linguistics at Boğaziçi University, Istanbul, and an IMPRS affiliate at the Max Planck Institute for Psycholinguistics, Nijmegen. I hold an M.A. (GPA: 4.0) and B.A. Summa Cum Laude (GPA: 4.0) from Boğaziçi University.
My research sits at the intersection of cognitive science and NLP, investigating how visual-spatial modality shapes language in deaf signers, hearing gesture users, and vision–language models. I work with Dr. Kadir Gökgöz and Dr. Nazik Dinçtopal Deniz at Boğaziçi, and collaborate with Dr. Aslı Özyürek and Dr. Esam Ghaleb at MPI.
