Paulina Deptula, PhD

University of Copenhagen

I received my PhD in biotechnology at the Department of Food and Nutrition, University of Helsinki in 2017. During my PhD, I focused on biosynthesis of vitamin B12 by Propionibacterium freudenreichii and studied different aspects of the bacterium itself. It is then that we realised P. freudenreichii has a strikingly diverse array of restriction-modification systems, which gradually led to my interest in Propionibacterium phages. I am currently a postdoctoral researcher at the Department of Food Science, University of Copenhagen. My current project is focusing on analysis of defence systems in P. freudenreichii.
