Research
Research in our lab combines non-invasive brain imaging methods such as electroencephalography (EEG), magnetoencephalography (MEG), and transcranial magnetic stimulation (TMS) with advanced analytics to study brain function, with the goal of creating novel technologies and digital biomarkers to improve brain function assessment in health and disease. Sample projects include examining the neural correlates of information processing following spontaneous blinking (blink-related oscillations), developing imaging-based techniques and analytic algorithms to advance brain function assessment in a variety of situations (e.g. clinical disorders, everyday scenarios like driving, and specialized environments like aircraft cockpits), as well as developing portable, user-friendly devices for objective brain function monitoring in real life.
