Dr. Gülin Öz is a professor in the Department of Radiology who specializes in magnetic resonance spectroscopy (MRS). She 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.

Dr. Öz uses high field, multi-nuclear MRS to delineate neurochemical and metabolic alterations in neurodegenerative diseases and diabetes. She leads a program in spinocerebellar ataxias and has studied neurochemistry in Parkinson’s, Huntington’s, Alzheimer’s diseases and ALS. She co-led an effort by the MRS Consensus Group to provide guidelines for MRS data acquisition and analysis, quality assessment, and interpretation. She leads a multi-site Bioengineering Research Partnership (BRP) for across-platform harmonization of advanced MRS methods. Finally, she serves as MPI in the READISCA study, an international clinical trial readiness initiative in spinocerebellar ataxias. The goal of the imaging effort in READISCA is to validate MRI and MRS biomarkers in the earliest stages of neurodegeneration.

Research Interests:

  • 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.
