Summary Research assistant working on infant social cognition and early risk screening, modeling parent–infant synchrony across behavior (video/annotations), brain (EEG), and physiology (ECG). Builds play-based, naturalistic tasks; develops end-to-end pipelines that derive novel social interaction metrics; and constructs large multimodal datasets for predictive modeling and clinical translation. Experience spans optogenetic rodent models, dynamical systems approaches, and cross-disciplinary collaboration.

Work

  • 2024.01 - Present
    Research Assistant
    Nanyang Technological University, Singapore
    Developing an end-to-end pipeline integrating multimodal parent–infant play data (EEG, ECG, video, behavioral annotations) to derive novel social interaction metrics and train predictive models for early neurodevelopmental risk.
    • Curate one of the largest datasets of its kind to train predictive models of infant neurodevelopmental profiles from as early as 12 months.
    • Advance clinical translation by designing novel social interaction metrics with applications in both diagnostic and commercial settings.

    AGEWELL project on cognitive aging in a socioeconomically diverse Malaysian cohort.
    • Recruited and assessed older adults (60+) with neuropsychological testing and EEG.
    • Derived event-related potentials as neural markers of executive function and aging-related decline.

    Sociometric AI Screening Tool to Risk-Stratify Infant Neurodevelopmental Trajectories
    Developing an early-screening framework from naturalistic parent–child interactions with children aged 6–36 months to identify neurodevelopmental risk.
    • Developed play-based tasks indexing working memory, inhibition, and cognitive flexibility in naturalistic parent–child contexts.
    • Linked social contingency and EEG/ECG synchrony to emerging executive functions.
    • Validated social interaction metrics against clinician ratings and standardized developmental screens for clinical translation.

    Integrated behavioral assays with optogenetics to test the causal role of prefrontal neural synchrony in naturalistic parent–offspring social learning
    • Applied recurrence quantification analysis to dam–pup interactions and foraging behavior.
    • In vivo optogenetic manipulation; immunohistochemical verification of medial prefrontal targeting.
    • Maintained and validated transgenic lines (e.g., PV-Cre/ChR2).
