Faculty and Staff
Dr. Gülin Öz is an associate professor in the Department of Radiology who specializes in magnetic resonance spectroscopy (MRS). Dr. Oz graduated from Bosphorus University in Istanbul, Turkey with BS degrees in Physics and Chemistry and obtained her PhD in Biochemistry at the University of Minnesota. She continued with postdoctoral training at the Center for Magnetic Resonance Research (CMRR) where she joined the faculty as assistant professor in 2006. Here she also served as the MR Core Director of the General Clinical Research Center (GCRC) from 2005-2009.
- To develop high and ultrahigh field MRS methodology for human and rodent applications.
- To establish in vivo 1H MRS biomarkers of neurodegeneration, in parallel studies with patients and transgenic mouse models, with particular emphasis on movement disorders such as spinocerebellar ataxias and Parkinson’s disease. Such biomarkers are expected to facilitate early disease detection and treatment monitoring in pre-clinical and clinical trials.
- To determine the effects of diabetes and the hypoglycemic consequences of intensive insulin therapy on brain glucose and glycogen metabolism in humans and to elucidate pathogenic mechanisms of hypoglycemia unawareness syndrome using 1H and 13C MRS.
