My current research seeks to investigate the effects of electrical brain stimulation on the function of the limbic system, a network of brain regions exerting broad control over emotion. I use a convergence of neuroscientific techniques to study this system, including neuroimaging and neurophysiology, as well as targeted measures of behavior and autonomic activity. My work at Emory has centered around patients receiving deep brain stimulation for treatment-refractory major depressive disorder and patients with refractory epilepsy undergoing invasive intracranial monitoring for seizure focus localization (CV).

My special expertise resides in the functional neuroimaging and neuromodulation technologies. My research seeks to characterize the structural and functional organization of depression circuits using diffusion tensor imaging and functional MRI for applications in the imaging biomarker of depression and optimizing surgical targeting for deep brain stimulation in treatment-resistant depressed patients. Currently, I am developing the prospective target selection algorithm and toolbox using connectivity analysis for successful SCC DBS treatment. (CV)

The aim of my research is to understand how brain network pathology contributes to maladaptive thinking, feeling and behavior – and how these may be corrected with targeted intervention. My research reflects early efforts to identify electrophysiological targets for the treatment of depression with cognitive therapy and brain stimulation. I am excited by the growing prospect of psychotherapeutic services that integrate treatment for the mind with treatment for the brain, and maximize lasting benefit from both. (CV)

Graduate Students:

Vineet Tiruvadi
Email: vtiruva@emory.edu

I am an MD/PhD student at Emory+GeorgiaTech and pursuing a PhD in Biomedical Engineering. My interests revolve around understanding brain signaling changes following deep brain stimulation for depression in the context of network modeling and control. I aim to work at the intersection of neurosurgery, psychiatry, electrical engineering, and computational neuroscience as an academic physician-scientist.

I am a 2015 HHMI Medical Fellow at the Depression Biometrics lab.  I arrived as a Medical Student at the University Of Maryland School Of Medicine with an interest in pursuing a career in academic psychiatry.  My primary research interests concerns the ability of DBS to entrain natural operating frequencies of the waking, behaving brain, and the effect of stimulus frequency on producing optimal clinical outcomes in the SCC-DBS population.
