Research Interests

My research is centered on two main areas: 1. Optimizing the clinical application of non-invasive brain imaging and stimulation methods in diagnostic and therapeutic domains, and 2. Characterizing functional characterization of the speech and limb motor networks and disease, injury, and treatment induced plasticity in these systems. These research objectives are focused around human speech and motor systems and use multimodal neurophysiological imaging methods. The neuroimaging methods used include magnetoencephalography (MEG), Transcranial magnetic stimulation (TMS), and functional magnetic resonance imaging (fMRI).

Ongoing research projects include examining the therapeutic effects of TMS in speech and voice disorders in Parkinson's disease, and epilepsy. Other studies include developing population normative data of TMS derived neurophysiological parameters and optimizing non-invasive brain stimulation and functional imaging in the context of presurgical mapping.

The lab is also investigating functional connectivity of speech and limb motor systems. Studies are also characterizing changes in the speech motor system resulting from Parkinson's disease and the compensatory adaptations in the network following voice treatment as well as identifying neurophysiological correlates of performance enhancement resulting from motor training and adjuvant TMS.
