Apostolos K. Rizos
Professor of Physical Chemistry 

Apostolos Rizos was born in Vasilika, Larissa, Greece, finished his high school in Nea Ionia, Volos,  and received his B.S. in Chemistry in 1979 from the Aristotelian University of Thessaloniki in Greece. He went to the US in 1980 to pursue graduate studies and received his M.A. Degree in 1983 (Chemical Physics) and Ph.D. degree in 1985 (Physical Chemistry) both from the State University of New York at Binghamton under the supervision of Prof. David C. Doetschman. The title of his Ph.D. Thesis was "Chemical Kinetics of Nitrosylhemoglobin Ligand Exchange and Photochemistry". His post-doctoral research position was on resonance Raman studies of biological systems at Northeastern University (1985-1986). After spending 12 months in the Greek Army (obligatory military service) he then moved to the University of Crete. In January 1990 he was elected as a lecturer in Physical Chemistry at the Department of Chemistry. In 2000 he was promoted to Associate Professor and from June 2007 to Professor in Physical Chemistry.

RESEARCH TOPICS

  • Chemistry in Health and Disease - Connection between diet and our physiology in different diseases

    •      During the last few years there has been an increased interest regarding the relation between diet and health.

    •      This is due to the important role nutrition plays throughout our lifetime, since this role affects the growth of our body during childhood, the risk for acute and chronic diseases as well as the maintenance of physiological biological processes.

    •       An important goal of our research is to clarify the knowledge about the relationship between our diet and the molecular processes that involve the food we eat.

  • Structure and Dynamics of Biopolymers and Biological Macromolecules

LAB FACILITIES

Static and Dynamic Light Scattering in FORTH- IESL.
