Çağrı Çöltekin
I work in department of Information Science (Informatiekunde) at the University of Groningen (RUG). I recently finished my PhD on simulation of language acquisition in RUG, under the supervision of John Nerbonne. During my PhD work, I have been affiliated with Center for Language and Cognition Groningen (CLCG) and school of Behavioral and Cognitive Neurosciences (BCN).
Previously, I studied Cognitive Science (MS) and Computer Engineering (BS) in Middle East Technical University, Ankara, Turkey. In another life (that run in parallel at times), I worked as System/Network Administrator at RIPE NCC, METU Computer Center and TÜBİTAK.
