Lazaros Gagaletsios has a first degree in Biochemistry and Biotechnology, University of Thessaly, Greece and now he is a graduate student in Clinical Applications of Molecular Medicine in the Faculty of Medicine, University of Thessaly, Greece. His main research interests are focused on prevalence and analysis of CRISPR/Cas systems in Gram-negative bacteria. His projects aim to understand the mechanism and function of CRISPR/Cas systems (especially in Pseudomonas aeruginosa and Escherichia coli, which were isolated in Greece) and to determine the origin of sequenced spacers. Additionally, he is interested in the evaluation of mechanisms involved in the virulence of pathogenic bacteria and the use of compounds to suppress the expression of those factors. Also, now he΄s working on Ration project as a biologist.
