Job title:
Associate Professor

Responsibilities:

School Mentor for Early Career Researchers
Department Director of Academic Tutoring
Steering Committee and lead of Neuroscience Theme for Centre for Literacy and Multilingualism (CeLM).

Areas of interest

My research is on experience-based neuroplasticity, with a primary focus on the effects of bi-/multilingualism on brain structure and function, investigated with behavioural and MRI (functional and structural) methods.

My research interests include:

Are brain structure and function, and cognition, affected by learning additional languages?
How are these effects modulated by the individual experiences of the language learner?
How do these effects interact with typical brain development and ageing, and what are the implications for age- or disease- related neurodegeneration?
Are there particular effects on the brain and/or cognition caused by language situations like diglossia, digraphia and biliteracy?
