Dr. ir. Haitham SGHAIER (born April 2, 1977), is an Assistant Professor of Radiation Biology at the National Centre for Nuclear Science and Technology (CNSTN) in Tunisia. He was educated at Technical School (Kebili, Tunisia), INAT (Tunis, Tunisia) and ENIS (Sfax, Tunisia). He obtained a Master Degree from Kiryu Faculty of Engineering (Japan) and a Ph.D. following his research done at the Japan Atomic Energy Agency (Japan). In 2007, he joined the CNSTN. Haitham SGHAIER has published extensively on the evolution of ionizing-radiation-resistant prokaryotes. In 2007, Haitham SGHAIER draw attention to major discrepancy that has emerged between the ‘‘desiccation adaptation hypothesis’’ and recent findings in computational biology, experimental research, and terrestrial subsurface surveys. He proposed an alternative hypothesis, suggesting that desiccation tolerance could be a consequence of bacterial adaptation to ionizing radiation (radiation adaptation hypothesis). He won the 2002 best prize of Gunma University of the Third Speech Contest, in Japanese about peace, for foreign students.
