I work at the interface of neuroscience and engineering to study the dynamic behavior of brain circuits. Relying on advanced medical imaging techniques, my work seeks to address how specific neuronal populations in the brain influence the larger networks in which they are embedded. Research in this area will help elucidate the mechanisms of current "black box" therapies, such as deep brain stimulation, as well as drive the development of novel, more targeted and effective treatments.
