Professor Tamar Keren-Portnoy

I'm a Professor at the Department of Language and Linguistic Science at the University of York. I got my PhD at the Hebrew University of Jerusalem. I am interested in the ways in which babies shape their own learning by building on what they've done before. I am also interested in the ways in which adults speak to children and what children learn from the speech they hear. I have recently started to work with clinicians and charities to test ways of improving language outcomes in baby populations who are at risk of language delay.

Dr Catherine Laing

I am a Senior Lecturer in Developmental Linguistics in the Department of Language and Linguistic Science at the University of York. I got my PhD from the University of York and have since worked in North Carolina and Cardiff. I am interested in how babies make the transition from babble to words, and I use methods such as eye-tracking and lingual (tongue) ultrasound to find this out! I also work with speech and language therapists and other practitioners to find ways to apply my work in real-world settings.

I’m a Postdoctoral Research Associate at the University of York. I’m interested in how the things that babies say and hear as they grow and change can shape their individual journeys from the first sounds to the first words. My PhD, which I also completed at York, explored the relationship between babble and how the brain becomes more specialised during the first year of life. I’m currently working on Catherine Laing’s project using ultrasound of the tongue to investigate how the sensory and motor information that babies get from producing early sounds might help prepare them for one day joining in the conversations they hear around them. Before this, I also worked at Leeds Beckett, Edinburgh, Huddersfield, and Leeds in linguistics, psychology, education, and speech and language therapy research.

I am the Lab Manager for SENFM in the Department of Language and Linguistic Science at the University of York. I am currently finishing my MSc in Developmental Psychology from the University of Kent, exploring young children’s thinking, and social and moral development. My are interests are in how everyday experiences and interpersonal relationships shape our development. I am particularly interested in the role of parents in contributing to children’s acquisition of language and socio-moral values.  Currently, I am working on Catherine Laing’s project using ultrasound of the tongue to explore how sensory and motor experiences contribute to language learning and development in early infancy.


Dr Laura Boundy

I am a Postdoctoral Research Associate at the University of York. I completed my PhD at the University of Manchester and have previously been involved in several projects at the University of Manchester exploring early language development and interventions to support this. I’m interested in how pre-verbal infants learn from their environment and from early interactions with their caregivers, to develop the necessary skills for later language development. I am also interested in how we can develop and evaluate interventions aimed at supporting language development in those at risk of language delay.

I am a Postdoctoral Research Associate in the Department of Language and Linguistic Science at the University of York. I recently completed my PhD at the University of Göttingen, Germany, where I investigated parent-child dynamics in social interactions. My research focus is on the development of young children's expressive language, exploring how their caregiver's input and caregiver-child interactions influence this process. Natural social interactions are a key part of children's daily life adventures, and examining their impact and influence would help us to better understand the underlying mechanisms of language learning.

Why do babies sleep so much? Would it surprise you that they actually learn while sleeping? My PhD project investigates whether night-time sleep and naps are linked to how babies learn new words. In my research, I also look at the associations between infant sleeping habits and the development of their vocabulary and motor skills. I also work on other projects exploring ways to use ultrasound to image infants' vocal tract, collaborating with speech and language therapists to measure babies' early communication skills, and investigating how parents speak to their children in different cultural contexts.

I’m a joint PhD student at the University of York and Aarhus University in Denmark. My PhD project investigates how children discover, explore and learn speech sounds as well as how their active participation in language development influences how caregivers speak to them. To gain deeper insights into the feedback loops between caregivers and children, I use different analytic methods, including acoustic analysis of sound data from human and non-human animals, meta-analyses, and computational modelling. By examining these dynamic social interactions, I hope to gain a better idea of how children actively learn to produce the speech sounds they need to communicate.

I am Associate Head of Languages and Linguistics at York St John University.  I did my PhD at the University of York.  My research looks at what happens when a child is exposed to multiple dialects while they are acquiring language.  How does a child resolve contradictory patterns in the accents around them in their own developing speech production?  Do they acquire the accent of the local community, their parents’ accent, or something in between?  I’m interested in learning about what looking at the language development of these children can tell us about the ways that most typical children also learn to pronounce their language.
