    Duygu Tosun-Turgut, PhD, is an Associate Professor and Co-Director of the Center for Imaging of Neurodegenerative Diseases (CIND) at the San Francisco Veterans Affairs Medical Center. Dr. Tosun 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.

    Dr. Tosun’s long-term research goal is to develop new algorithmic approaches for processing and analysis of multi-disciplinary/modality data including neuroimages, genetics, proteomics, as well as cognitive functioning measures in a unified framework by using recent advances in image processing, medical physics, and computation medicine. The primary aim is to identify multi-disciplinary/modality biomarkers for detecting the changes associated with disease specific neuropathology, improving understanding of pathophysiological progression and potentially providing a means of monitoring the efficacy and regional specificity of drug therapy for neurodegenerative diseases. This will have a broad use in early diagnosis, facilitating initiation of prevention strategies in those at risk, and boost the power of drug therapy trials by selecting those at greatest risk of neurodegenerative diseases.

    Dr. Tosun is a reviewer for 17 scientific journals. She has 29 published articles and she has written 30 peer-reviewed articles, 50 abstracts, and 5 significant publications.
