    <p>I am currently a Research Professor at
    <a href="https://www.chosunbabylab.com/">Chosun Babylab</a>
    and the
    <a href="https://cds.chosun.ac.kr/">Center for Data Science in the Humanities</a>
    at Chosun University in Gwangju, South Korea.</p>

    <p>My research focuses on early language development,
    particularly how young children learn from everyday
    linguistic input and social interactions. Using
    eye-tracking, naturalistic recordings, corpus analysis,
    and computational methods, I investigate language
    acquisition across both experimental and real-world
    settings. I am especially interested in how different
    approaches can complement one another in understanding
    early language learning.</p>

    <p>My recent work examines Korean child-directed speech,
    caregiver–child conversational dynamics, statistical
    word segmentation, and automated analysis of daylong
    recordings. I also study early vocabulary development,
    including how children's word knowledge can be
    assessed through parental reports and behavioural
    measures.</p>

    <p>During my PhD, I developed
    <a href="https://github.com/junhochai/BabyLex2.0">
    Bayesian IRT-based adaptive assessments</a>
    for tracking early vocabulary development in multilingual
    children. These brief, browser-based tools were designed
    to support efficient assessment and targeted intervention,
    and have been integrated into
    <a href="https://github.com/lochhh/e-Babylab">
    e-Babylab</a>.</p>

    <p>Before joining Chosun University, I was a Lecturer
    at Sunway University, where I taught Biological Psychology
    and Research Methods. I enjoy teaching and working with
    students, particularly when it comes to developing
    research questions, exploring data, and learning how
    to make sense of findings.</p>

    <p>You can find more about my work through my

    Google Scholar profile</a>.
    Some of my research tools and projects are also available
    on <a href="https://github.com/junhochai">GitHub</a>.</p>

    <p>I am also experimenting with a tool for
    <a href="{{ '/emotionapp' | relative_url }}">
    testing emotion perception</a>.</p>

    <p>Outside of research, I enjoy spending time with my
    wife and our two daughters, reading, and making things
    out of wire. I am also learning Korean and exploring
    life in South Korea, with my family</p>
