Profile

My research interests include auditory perception in different domains (e.g., language and music), language acquisition in both L1 and L2, and atypical development in childhood.

In my PhD, I studied how different popluations perceive pitch in language and music, and how native tone lanugage listeners build up phonological knowledge of the lexical tones. Since my PhD, I've worked extensively with infants. My expertise includes various infant research methods, from behavioral measurements to EEG, and parental surveys. 

I work in Utrecht University Dynamics of Youth project Early Prediction of Dyslexia: Machine Learing in Infant Data. Together with Dr. Hugo Schnack in Utrecht Medical Center (UMC) and Prof. Dr. Frank Wijnen, we try to develop early diagnosis tools for dyslexia. 

Skills:

Adult and infant behavioral experiments (from design to analysis)

Adult and infant EEG measurement and analysis

Large-scale parental survey design, storage, digitalization and analysis

Machine learning

Matlab programming.

Completed projects

Project:
Prediction of Dyslexia in Infants Using Machine-learning (PODIUM) 01.03.2014 to 30.04.2016
General project description

The current project will use machine learning techniques to explore if data on speech processing in infancy can predict the occurrence of later literacy difficulties in individual children. We perform a proof of principle study on existing vocabulary and speech discrimination data from infants at risk of DD and low-risk controls.

Project:
Cross-domain perception of pitch in infancy, an EEG study 20.10.2014 to 20.04.2015
General project description

This project examines how infants perceive pitch in speech and music using EEG method. 4-, 8-, and 12-month-old infants' brain response to music and speech stimuli are analyzed and compared to adults' response.

Project:
China Exchange Program: The Early Acquisition of Speech Prosody: A comparative study of Dutch and Chinese. 01.01.2011 to 31.12.2014
General project description

The project aims to faciliate collaboration between Chinese Academy of Social Science (CASS) and Utrecht Institute of Linguistics (Uil OTS). CASS and Uil OTS have worked and are still working together on topics such as lexical tone perception by native versus non-native infants/adults, acquisition of lexical tones, cross-linguistic perception and acquisition of stress, etc. The main focus is how prosody perception develops in infancy.
