Dr. Ir. Haïtham SGHAIER (TUNAC ISO 9001/17025/15189 Lead/Technical Assessor), is an Engineer in Biotechnology and Professor (Associate) of Radiation and Computational Microbiology at the National Center for Nuclear Sciences 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 (JAEA, Japan). Being a glossophile, he won the 2002 best prize of Gunma University of the Third Speech Contest, in Japanese about peace, for foreign students. In 2007, he joined the CNSTN. He won the 2016 TWAS Young Arab Scientist (YAS) Prize. Basic research of Dr. Ir. Haïtham SGHAIER is related to the study of microbial resistomes, (oxidative) stress tolerance and interactions among prokaryotes/eukaryotes through computational biology and omics tools (http://orcid.org/0000-0002-8210-5345). He has published on the evolution of ionizing-radiation-resistant prokaryotes (IRRP). In 2007, he 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). Also, he has published on bioremediation issues, particularly on bioremediation of radioactive waste using IRRP. Currently, he is implicated in various ongoing projects: multi-omics analyses (https://www.nature.com/articles/s41598-017-18839-0; https://www.nature.com/articles/ismej2015108), databases (http://home.isima.fr/irrb/; http://www.radiop.org.tn/; etc.) about IRRP, extremophiles, biotechnologically-relevant or disease-associated microbes, certification and accreditation of laboratories (ISO 11137, etc.).

Latest work with IntechOpen by Haitham Sghaier

Besides the Introductory Chapter that gives a brief overview of archaeal applications, the present book contains four chapters. The first chapter, by Castro-Fernandez et al., provides an interesting depiction of the phylum Euryarchaeota and its biotechnological applications. The second chapter, by Ben Hania and coauthors, focuses on the promotion of the idea that some specific Archaea are potential next-generation probiotics. The third chapter, by Torregrosa-Crespo et al., emphasizes the main characteristics of biocompounds from haloarchaea and their potential uses in biomedicine, pharmacy, and industry. The concluding chapter, by Mizuno et al., proposes a plasmid curing approach for improving the potential of thermophiles in various biotechnological applications and opens new perspectives on industrial valorization.
