Duygu Tosun-Turgut, PhD
Professor
Radiology
School of Medicine

Dr. Tosun-Turgut obtained her BSc in Electrical and Electronic Engineering from Bilkent University, Turkey in 1999, and she received her MSE in Electrical and Computer Engineering from The Johns Hopkins University, Maryland in 2001. In 2003, she completed her MA in Mathematics from The Johns Hopkins University, and she earned her PhD in Electrical and Computer Engineering from The Johns Hopkins University in 2005, followed by a postdoctoral fellowship in Neurology from the University of California, Los Angeles in 2008. Her independent research career began as a Research Scientist at the Center for Imaging Neurodegenerative Diseases (CIND) at UCSF, followed by a faculty appointment at the Department of Radiology and Biomedical Imaging at UCSF in 2011. Since her initial faculty appointment at UCSF, she first appointed as Co-Director of CIND and then transitioned to the Founding Director of the Medical Imaging Informatics and Artificial Intelligence.

Dr. Tosun-Turgut’s research focuses on neuroimaging of neurodegenerative diseases and psychiatric disorders and aims to apply advanced imaging technology for discovery of multi-modal biomarkers to detect the progression of neurodegenerative pathologies before they cause irreversible damage to the brain. She aims to develop validated biomarkers of neurodegeneration that may be used for early diagnosis, initiation of prevention strategies in those at risk, monitoring of efficacy and regional specificity of therapies, and clinical trial enrichment. Her research has been funded by NIH, the California Department of Public Health, Department of Defense, Alzheimer’s Association, Michael J Fox Foundation, and industry partners.
