Broadly, Doğuş is interested in the relationship between language and cognition, in particular in first and second language acquisition and processing. His work draws on corpus analysis and psycholinguistic experimentation to address research questions such as the following: What role do multiword expressions (e.g. collocations, idioms) play in language processing? What is the role of frequency in language processing? What role do individual differences play in language acquisition/processing? What is the nature of implicit learning mechanisms? How do typological characteristics of languages affect processing? What is the impact of typological distance between first and second language on learning?

He is currently a research associate at DTAL, working for the Leverhulme Trust funded research project Linguistic Typology and Learnability in Second Language with Dora Alexopoulou and Ianthi Tsimpli. Prior to joining Cambridge, he received his PhD from Lancaster University and worked as a research associate at the University of Leeds.
