Laboratory of Structural & Supramolecular Chemistry

Dr. Emmanuel Saridakis


Emmanuel Saridakis obtained a BSc degree in Physics in 1991 and a PhD in Biophysics in 1995 at the Physics Department of Imperial College London. His research topic, under the supervision of Professor David Blow, was the study of nucleation and growth of protein crystals. He also holds a University of London postgraduate degree in the History and Philosophy of Science. He has worked as a research associate at the Physics Department and the Faculty of Medicine of Imperial College London, at the University of Athens and at the Institute of Molecular Biology and Biotechnology/ FORTH in Heraklion, Crete.  He joined the Laboratory of Structural and Supramolecular Chemistry at the Institute of Physical Chemistry of NCSR “Demokritos” in 2006 and became a Researcher D in 2008 and Researcher C in 2012. He is also an Honorary Research Fellow at the Imperial College, Faculty of Medicine. His research interests are in the theory and methodology of macromolecular crystallization and in macromolecular crystallography.
