Grzegorz Wegrzyn has graduated from University of Gdansk, Poland. In 1987 he obtained MSc degree in biology, and in 1991 PhD degree in molecular genetics. His PhD thesis was focused on the regulation of DNA replication in starved cells. Then (in 1991), he was a research fellow at the Department of Biochemistry, University of Nottingham Medical School (UK), where he worked on the mechanisms of gene expression regulation in bacteria. In 1992 he was a post-doctoral researcher at Center for Molecular Genetics, University of California at San Diego (USA), where he investigated regulation of viral DNA replication. Since 1996 he is a Professor and Head of Department of Molecular Biology at the University of Gdansk (Poland). In his laboratory, several projects are conducted, which are focused mainly on regulation of gene expression and DNA replication, control of development of bacteriophages, the use of bacteriophages in biotechnological applications, and mechanisms and new treatment methods of human genetic and neurodegenerative diseases. Grzegorz Wegrzyn is a co-author of over 500 scientific articles in peer-reviewed journals and over 600 communications on scientific conferences. He supervised 57 PhD theses, and led over 30 research projects within both national and international grants. He is a member of American Society for Biochemistry and Molecular Biology, American Society for Microbiology, Society for Experimental Biology and Medicine, and International Society for Plasmid Biology. He is an editor of several scientific journals, including FEMS Microbiology Reviews, Microbial Cell Factories (Editor-in-Chief), Metabolic Brain Disease (Deputy-Chief-Editor), Plasmid, Scientific Reports (Senior Editor), and Acta Biochimica Polonica (Editor-in-Chief).
