This research team focuses on the development of exosome biomarkers for autism spectrum disorder (ASD), Alzheimer's disease, and Parkinson’s disease. Exosome biomarkers could facilitate the development of clinical targets for early intervention to prevent, delay, or reduce the severity of these diseases.

The team are also working on the functional assay to validate patient-specific hiPSC-derived neurons using calcium imaging, whole-cell patch clamping technique, and micro-electrode array (MEA), in order to model neurodevelopmental and neurodegenerative diseases.
