Isabel Nadine Jensen

Isabel Nadine Jensen is a Postdoctoral Fellow in Scandinavian linguistics at the Institute of Linguistics and Scandinavian Studies, Faculty of Humanities, University of Oslo. Her research centers on second and third language acquisition, with a focus on Norwegian as a second language and the Bottleneck Hypothesis in multilingual learning contexts.

Her academic background includes a PhD in Linguistics from UiT The Arctic University of Norway (2022), an MPhil in English Linguistics (2016), a Practical-Pedagogical Education degree (2017), and bachelor’s degrees in Language and Literature (2014) and Journalism (2013).

• PhD in Linguistics, UiT The Arctic University of Norway (2022)
• Practical-Pedagogical Education, University of Southeast Norway (2017)
• MPhil in English Linguistics, UiT The Arctic University of Norway (2016)
• BA in Language and Literature, UiT The Arctic University of Norway (2014)
• BA in Journalism, Nord University (2013)

Her research interests span second and third language acquisition, crosslinguistic influence, morphosyntactic development, dialect acquisition, and the cognitive and neural underpinnings of multilingualism. She investigates how linguistic similarity, bilectal exposure, and prior language knowledge shape L2 and L3 learning trajectories, particularly among Norwegian and migrant populations.

The analysis of her recent publications reveals a consistent focus on the interplay between syntax, morphology, and crosslinguistic transfer in multilingual acquisition. Her work employs experimental, corpus-based, and neurocognitive methods across diverse populations, including Polish migrants in Norway and L1 Norwegian learners of English. A recurring theme is the testing and refinement of the Bottleneck Hypothesis, particularly in how morphosyntax presents a critical challenge in language learning.

Isabel Jensen is affiliated with the research group Second and third languages: Acquisition and use at the University of Oslo. She has not been mentioned as advising students or receiving specific scientific awards in the provided texts.

She has authored or co-authored numerous peer-reviewed articles in leading journals such as Language Learning, Second Language Research, International Journal of Bilingualism, and Frontiers in Psychology. Her collaborative work reflects strong international and interdisciplinary engagement in the field of multilingualism and language acquisition.
