Ph.D. Candidate in Intelligent Science and Technology

Building AI that learns across brains, species, and modalities.

I develop data-efficient, robust, and generalizable learning methods for neural signals under limited labels, strong heterogeneity, and distribution shifts. My research spans cross-species and cross-modality transfer, interpretable EEG decoding, multimodal learning, and physiologically grounded data generation.

From neural signal decoding to foundation models for brain disorder diagnosis

My long-term goal is to build trustworthy cross-species, multimodal, and multitask foundation models for brain-disorder screening, prognosis, treatment-response monitoring, and rehabilitation.

I am particularly interested in shared neural representations across epilepsy, Alzheimer’s disease, hypoxic–ischemic encephalopathy (HIE), amyotrophic lateral sclerosis (ALS), and related neurological disorders.
