Xuran Han

Dr Xuran Han BA, MA, PhD

Lecturer in Psychology

Xuran Han joined the School of Human Sciences as a lecturer in April 2023. She received her PhD in Bilingualism and Cognition from the Department of Psychology and Human Development at the Institute of Education, University College London, in November 2022. Xuran completed her MA in Applied Linguistics at the Institute of Education, University College London in 2018.

She has a background in both cognitive psychology and psycholinguistics. Her research interests mainly focus on the interconnections between individuals’ bilingual language experience development and their dynamic neurocognitive adaptions across the life span. Before joining the University of Greenwich, Xuran worked as a senior postgraduate teaching assistant at University College London, supporting psychological research module teaching at both undergraduate and postgraduate levels.

Her current teaching includes cognitive mechanisms in bilingual language processing, quantitative research methods in psychological research, and the psychology of language and communication. She also involves in supervising undergraduate and postgraduate quantitative research projects.

Research / Scholarly interests

Xuran’s research interests mainly focus on the interconnections between individuals’ life-long experiences, including language use and social activities, and their neurocognitive development across the life span. Specifically, her research aims to understand the cognitive mechanisms underlying bilingual language processing and the impacts of bilingual experience on domain-general cognitive control. Focusing on bilinguals from diverse cultural communities and age groups, she has explored the roles of habitual bilingual language use experience and interactional contexts in cognitive control modulation.

By using the convergence of computational modelling and behavioural experiment approach, her research intends to explore some of the essential questions in the bilingualism research area, including 1) how lifelong bilingual language experience modulates bilingual individuals’ domain-general cognitive control development, and 2) how cognitive control adapts to dynamically-changing cognitive demands in language processing (i.e., real-time bilingual language comprehension and spontaneous language production).
