Tiny errors in electrode placement can determine success or failure of Parkinson’s surgery. This research develops high-resolution Polarization Sensitive Optical Tomography to map brain anatomy at micrometer scale—over 100 times finer than MRI. Automated scanning and 3D reconstruction create detailed connectivity maps, improving surgical precision and neuroscience understanding.

This research explores motor imagery as a rehabilitation tool after stroke. Brain imaging revealed sex-based differences in neural activation, with females showing greater efficiency. Practice improves patterns in both sexes. Understanding these differences enables personalized, home-based rehabilitation that may enhance recovery of arm and hand function.

My research explores whether people with semantic dementia can relearn everyday words through simple, repeated online training. Patients practiced picture–word pairs daily for two months and showed strong, lasting improvements that transferred to real-life use. The findings offer hope for patients and reveal how targeted practice can reshape the brain despite disease.
