2006-2010 Postdoctoral researcher at University College Cork.

Late 2006 I started as a postdoc in the group of Prof. van Sinderen at University College Cork in Ireland where I worked on gut health and Bifidobacterium genomics. My work was funded by an IRCSET Embark postdoctoral grant which I received in 2007.

My research included transcriptome analysis of B. breve , Lactococcus and lactobacillus grown both in vitro and in vivo under various relevant conditions, host transcriptomics, genome sequencing and analysis of novel probiotic strains. Furthermore I supervised students performing microbiology, genetics or bioinformatics projects. In addition I was responsible for running the BioIT and gene array platform of the Alimentary Pharmabiotics Centre. My work resulted in several publications listed below.
