Research

Research Summary/Interests

I am primarily interested in developing and advancing transcranial focused ultrasound for non-surgical neuromodulation in humans. My current research investigates combining tFUS with MRI as well as developing tFUS for stimulation of sub-cortical structures. The ultimate goal of this research is to translate these findings to clinical populations for therapeutic use. In addition, I also conduct research using conventional non-invasive neuromodulatory technologies like TMS and tD/ACS. This research looks at the effect of individual gyral anatomy on electric fields to advance subject-specific neuromodulation. Finally, I have a particular interest in the frontal cortex and how modulation of frontal areas through either disease, age or neuromodulation affect both local and downstream neuronal circuits and ultimately behavior. This research uses a multidisciplinary approach including neuromodulatory techniques TMS, tDCS and tFUS in combination with EEG, evoked potential, fMRI as well as computational methods including finite element modelling (FEM) and dynamic causal modelling (DCM).
