Stefan Tyski

Prof. Stefan Tyski graduated from the Faculty of Biology of the University of Warsaw, obtaining a M.Sc. degree in biology in the field of biochemistry in 1976. He started scientific work in 1977 at the Department of Bacteriology of the National Institute of Hygiene, dealing with research on staphylococci and the extracellular factors produced by them, as well as staphylococcal infections. In 1982 he obtained the PhD degree in natural sciences. In the years 1983-1985 he completed a post-doctoral  fellowship at the Department of Physiological Chemistry, Roche Institute of Molecular Biology in Nutley, New Jersey, United States. In 1987-1991 he cooperated with the Karolinska Institute and the National Bacteriological Laboratory, Stockholm, Sweden, completing series of several short visits and conducting serological tests.

He was awarded the degree of habilitated doctor of medical sciences in the field of medical biology - medical microbiology in 1992. He has been working in the National Medicines Institute since 1997. In the years 1998-2010 he was a member of the Standardization Committee No. 269 for disinfection and antisepsis of the Polish Committee for Standardization.  In 2001, started a cooperation, which is still ongoing, with the Polish Pharmacopoeia Commission, currently as vice-chairman.

In 2003, the President of the Republic of Poland awarded him with the academic title of Professor of Pharmaceutical Sciences. In the period 2006-2022 he worked at the Department of Pharmaceutical Microbiology of the Medical University of Warsaw.

He published over 250 scientific papers and led 8 national research projects. He promoted 8 PhD theses and organized 8 nationwide scientific and training conferences on pharmaceutical microbiology.

In 2016, he was elected the President of the Polish Society of Microbiologists and is currently serving his second term in the office.

His scientific interests focus mainly on: investigation of bacterial resistance mechanisms to antibiotics, chemotherapeutics, antiseptic, disinfecting and preservative agents: analysis by chemical and microbiological methods, the quality of medicinal products, medical devices, biocides, cosmetics, diet supplements (probiotics);  investigation of antimicrobial activity of non-antibiotics, synthesised compounds, natural material extracts; analysis of antibiotics interactions in complex drugs.
