Costas Papagiannitsis is an Assistant Professor in Microbiology in the Faculty of Medicine, University of Thessaly, Greece, since May 2018. His main research interests are focused on epidemiological surveillance of antimicrobial resistance (especially of resistance to carbapenems) in Gram-negative bacteria. His projects aim to execute molecular epidemiology of factors (like plasmids, transposons, insertion sequences and integrons) affecting dissemination of multi-drug resistance among nosocomial pathogens, and to characterize novel mechanisms conferring resistance to antibiotics. 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, he is a Specialty Chief Editor in Antibiotic Resistance and New Antimicrobial drugs of Frontiers in Cellular and Infection Microbiology. Asist. Professor Papagiannitsis has 87 publications in leading journals in the field of microbiology sciences, a Scopus H-index of 25 and 2092 citations (Google Scholar statistics: H-index of 29 and 2978 citations) and holds a Czech national patent (Czech Republic - PV 2013-473).
