Direction: Medical Radiology
Position:Full Professor
Okujava MikheiliMikheil Okujava graduated with honors from Tbilisi State Medical University (TSMU) Faculty of Medicine in 1994. In 1994-1996 he trained Neurology as resident in Department of neurology of TSMU. At the same time he got interested in imaging diagnostic methods and comlpeted the course of Roentgenoradiology in Tbilisi Medical Academy. In 1995-1996 he did internship in neuroradiology in different international centers (Moscow Institute of Neurology, Burdenko Institute of Neurosurgery (Moscow), Radiology Institute of Ruhr University (Bochum, Germany). Since 1995 he worked in the MRI department of Institute of Radiology and Interventional Diagnostics. In 1999 he obtained his PhD degree and in 2006 degree of DSc. In 2000-2001 as DAAD-stipend fellow was engaged in research work in Bethel Epilepsy Center (Bielefeld, Germany). Since 2007 he is invited lecturer in TSSU for Residents in Radiology. In 2017 he earned the TSSU Clinical Professor title. 2012-2017 Mikheil Okujava was Head of the Radiology Department of S. Khechinashvili University Hospital. Since 2010 he is active as Head of Neuroradiology and Neuroscience in Acad. F. Todua Medical Center. Since 2012 M. Okujava is elected Full Professor of Radiology in Iliauni School of Natural Sciences and Medicine. M. Okujava is Vice-president of Georgian Association of Radiology and expert of Ministry of Health of Georgia in this field. He is author of more than 30 scientific publications and one textbook.
