Anastasia S. Politou is a member of BRI-FORTH since 2007. She holds a B.Sc. in Chemistry from the University of Athens, Greece and M.Sc. and PhD degrees in Chemistry from New York University, USA. She worked as a post-doctoral fellow in the Structural Biology and Bio­computing Program of the European Molecular Biology Laboratory (EMBL), as a Visiting Associate Professor in the Chemistry Dept., Univer­sity of Crete and as  a Research Fellow in the National Institute for Medical Research, Medical Research Council, Mill Hill, London, UK. Since 2001 she has been working as an Assistant Professor at the Ioannina University, School of Medicine. A.S. Politou has published 35 research articles (over 1.080 citations). Her recent research interests include the study of the structure and dynamics of chromatin-related proteins and protein complexes. Her administrative work includes the establishment and management of the first High Resolution NMR facility in Greece (University of Crete, 1996-1999) and of the DNA Microarray facility at the University of Ioannina and the management of several research grants.
