John Stratakis was born in Heraklion, Crete, Hellas in 1974. He received his BSc In Physics from the University of Crete in 1997, his MSc in Medical Physics from the University of Surrey, UK, in 1998 and his PhD in Medical Physics from the Medical School of the University of Crete in Heraklion. He has served as a scientific associate of the Laboratory of Medical Physics at the same institution, and as a Laboratory Associate in the Technical Education Institution of Iraklion, Applied Informatics and Multimedia Division.

He is author or co-author in 17 scientific papers published in peer-review journals and his work has more than 170 citations. As a private medical physicist he served as a radiation protection officer of the County Hospital of Agios Nikolaos, Crete. He is a member of European Congress of Radiology and Hellenic Society of Medical Physics.

Currently he is a research fellow of the Department of Medical Physics of the University of Crete and a medical physicist of the University Hospital of Heraklion Crete.

He is married and father of two children.

Research interests

Monte Carlo dosimetry applied to radiographic and interventional procedures in order to :

  1. Quantify the radiogenic risks from medical procedures involving ionizing radiation.
  2. Optimize absorbed patient doses in radiological procedures.
