Professional Interests

Transcranial electrical stimulation (tES) is a promising non-invasive neuromodulation technique to improve brain functions.  While useful, observed tES outcomes have largely varied across individuals, and thus poses a concern in reliability and reproducibility of tES application. Using multimodal neuroimaging and computational models, my research goals are to improve tES reliability/reproducibility by: predicting tES current dose in stimulated brain regions, identifying/reducing possible sources of individual variability in tES outcomes, and investigating possible mechanisms of action that contribute to physiological changes caused by tES. In this lab, my current role involves data analysis in tES participants collected from our clinical trials. Specific projects include building a workflow that integrates all tES data analysis (behavior, neuroimaging and computational models) and developing new tools for quality control in tES to ensure reliable tES application across studies.
