EEG Source Imaging and Connectivity: Brain signal processing is quite challenging due to its poor signal quality, non-stationary, and high-dimensional nature. Currently, most of the researchers working on EEG-based Brain-Computer Interfaces (BCI) try to tackle these problems by developing algorithms based on optimization and regularization of spatial filters in the sensor space. My research focus is to develop such algorithms in the cortical source domain which could provide a better interpretation of the underlying neural activity and functional connectivity between different regions in the brain.

Multidirectional Arm Movement Decoding using EEG-based BCI: Conventional noninvasive BCIs have studied the sensor-space EEG features. My research focus is to improve the moment decoding performance using source-space EEG features.

Noninvasive Brain Stimulation for Upper Extremity Rehabilitation in Stroke: This line of my research is focused on targeted noninvasive brain stimulation for personalized neurorehabilitation to improve hand dexterity in stroke

Mobile Body/Brain Imaging of Postural Tasks in Traumatic Brain Injury: This research is focused on studying the underlying neural mechanisms of postural deficits after TBI using EEG source imaging and lower-limb surface EMG during the postural control task.
