    Dr. Vilja Siitonen graduated as PhD in 2016 from the Department of Biochemistry at the University of Turku in the “Antibiotic Biosynthetic Engineering”, ABE. During her PhD Vilja studied biosynthesis of the anthracycline antibiotic nogalamycin produced by Streptomyces nogalater. She found genes responsible for the late stage of the nogalamycin biosynthesis and characterized enzymes and low molecular weight intermediates from the nogalamycin biosynthesis pathway. After her PhD Vilja has been studying bioactive compounds from several Streptomyces strains employing a wide repertoire of methods including high resolution mass, high-performance liquid chromatography and nuclear magnetic resonance. Her main interest is to understand how antibiotics are built and to find novel bioactive compounds.
