Personal profile


ASSOCIATE PROFESSOR | Diagnostic, Molecular and Interventional Radiology, ASSOCIATE PROFESSOR | Neurosurgery


Ki Sueng Choi, Ph.D., is an Assistant Professor of Radiology and Neurosurgery. His special expertise resides in the functional neuroimaging, integration of multimodal neuroimaging strategies (sMRI, DTI, fMRI), and neuromodulation technologies. His research is focused on the characterizing the structural and functional organization of brain circuits using diffusion tensor imaging and functional MRI for applications in the imaging biomarkers to understand brain mechanism (disease subtypes and treatment effects) and optimizing surgical targeting for deep brain stimulation (DBS) in various psychiatric and neurological disorders including major depressive disorder, obsessive-compulsive disorder, Parkinson’s disease, and Tremor. 

Dr. Choi characterized the critical brain network that mediating subcallosal cingulate (SCC) deep brain stimulation antidepressant response with computational subject-specific DBS modeling and developed the prospective target selection algorithm/pipeline/toolbox for SCC DBS using diffusion tractography such as “Connectomic Targeting Approach” that provides a guidance for precise surgical implantation of leads and optimization algorithms for the selection of contacts in long-term stimulation.
